形成RGB之著色層亦易於實現彩色顯示。特別是在每畫 .素內建開關元件之所謂主動型液晶面板上,保證可獲得串 訊(crosstalk )較少且具有反應速度較快且對比高之畫 像。 此等之液晶顯不裝置(液晶面板),雖係以掃瞄線 2 00〜1 2 0 0條來做爲掃描線,以信號線3 00〜1 600條程度之 矩陣編組爲最常見之構成,但是最近,同步進行著對應於 顯示容量之增大之大畫面化及高精緻化。 圖1 7表示液晶面板之安裝狀態,構成液晶面板1之 一方之透明性絕緣基板,譬如,藉由使用導電性黏著劑來 連接對被形成在玻璃基板2上之掃描線之電極端子群5供 給驅動信號之半導體積體電路晶片3之COG ( Chip On Glass )方式’或譬如以聚醯亞胺樹脂薄膜作爲基層,把 具有鍍金或電鍍焊錫之銅箔端子(未圖示)之TCP薄膜 (2) 1300868 4 ’以包含導電性媒體之適當黏著劑壓接固定於信號線之 電極端子群6之TCP ( Tape Carrier Package)方式等之安 裝手段,使得電氣信號供給於畫像顯示部。於此雖然同時 圖示2種安裝方式,但是實際上可適當選擇任一方式。 7,8爲連接位於液晶面板1約中央部之畫像顯示部 內之畫素,和掃描線及信號線之電極端子5,6之間之配 線路,電極端子群5,6未必以相同導電材來構成。9爲 在對向面上具有共通於所有液晶單元之透明導電性之對向 電極之另一片透明性絕緣基板之對向玻璃基板或彩色濾光 片。 圖1 8係表示以在每畫素配置絕緣閘極型電晶體1 〇之 主動型液晶顯示裝置來作爲開關元件之等效電路圖,1 1 (於圖1 7上爲7 )爲掃描線,12 (於圖1 7上爲8 )爲信 號線’ 1 3爲液晶單兀’液晶單兀1 3在電路上是被當作係 做爲電容元件來看待。實線所描繪之元件類,係被形成於 構成液晶面板之一方玻璃基板2上,以虛線所描繪之所有 液晶單元1 3所共通之對向電極1 4係被形成於另一方玻璃 基板9之對向的主面上。 絕緣閘極型電晶體1〇之OFF電阻或液晶單元13之 電阻較低的場合或重視顯示畫像之灰階性的場合,把爲了 增大。。作爲負載之液晶單元1 3之時間常數之補助電容 1 5並聯於液晶單位1 3等電路上的改善。 圖1 9爲表示液晶顯示裝置之畫像顯示部之重點剖面 圖,構成液晶面板1之2片玻璃基板2,9,係藉由樹脂 -5- 1300868 (3) 性之纖維’珠子或形成於彩色濾光片9上之柱狀間隔物等 之間隔物材(未圖示),間隔數# m程度之特定距離而被 形成’其間隙(間隔),係於玻璃基板9之周緣部,藉由 有機性樹脂所構成之密封材及封口材料(皆未圖示)形成 密封之閉合空間,於此閉合空間塡充液晶1 7。 實現彩色顯示時,於玻璃基板9之閉合空間覆蓋稱爲 著色層1 8之染料或顏料之任一或雙方之厚度1〜2 " m程 度之有機薄膜,而提供顏色顯示功能,在此場合 玻璃基板9又被稱爲彩色濾光片(簡稱C F )。且, 隨著液晶材料1 7之性質不同,於玻璃基板9之上面或是 玻璃基板2之下面之任一者,或是於兩面上都貼附偏光 板’液晶面板1係作爲光電元件而發揮功能。現在,於市 面上所販賣之大部分液晶面板,乃使用 TN (扭轉向列 性)系液晶,偏光板1 9通常須2片。雖然未圖示,但是 透過型液晶面板,係配置背面光源來作爲光源,從下方照 射白色光。 接於液晶1 7而形成於2片玻璃基板2,9上之譬如厚 度〇. 1 // m程度之聚醯亞胺薄膜2 0,係使液晶分子配向於 決定方向之配向膜。2 1爲連接絕緣閘極型電晶體1 0之汲 極和透明導電性之畫素電極22之汲極電極(配線),多 與信號線(源極線)1 2同時形成。位於信號線1 2與汲極 電極2 1之間者爲半導體層23,將於後面詳述。在形成於 彩色濾光片9上被形成於相鄰接之著色層1 8邊界的厚度 0.1 V m程度之C r薄膜層2 4係爲了防止外部光射入於半 -6 - (4) 1300868 導體層2 3和掃描線1 1及信號線1 2之光遮蔽構件 所謂的黑矩陣(簡稱爲Β Μ )係屬習知習用技術。 於此’作爲開關元件說明有關絕緣閘極型電晶體 造與製造方法。於絕緣閘極型電晶體目前常用的有2 以其中一個作爲爲傳統例(稱之爲蝕刻截止型)而力口 紹。圖2 0表示構成傳統液晶面板之主動基板(顯示 用半導體裝置)之單位畫素之平面圖,圖21爲表示 (e ) A — A,,Β - Β ’及C — C,線上剖面圖,於以下簡 明其製造工程。 首先,如圖2 0 ( a )及圖2 1 ( a )所示作爲耐熱 耐藥品性及透明性高的絕緣性基板而選用的厚度〇 . μ m程度之玻璃基板2,譬如(康寧CORNING )公 製造之品名1 7 3 7之一主面上,使用SPT (濺鍍)等 製膜裝置選擇性地形成譬如Cr,Ta,Mo等或是覆蓋 合金或金屬矽化合物之膜厚〇·1〜〇.3#m程度之第1 層,而藉由微細加工技術,選擇性形成亦兼作閘極 1 1 A之掃描線1 1和積蓄電容線1 6。掃描線之材質係 性考量耐熱性和耐藥品性和耐氟酸性及導電性而加以 較佳。 爲了對應於液晶面板之大畫面化或高細緻化而P泽 描線之電阻値,雖以使用鋁來做爲掃描線之材料較 理,但是鋁於單體狀態,由於耐熱性較爲低,故層積 耐熱金屬如Cl.,Ta,Mo或是此等之金屬矽化合物, 於表面上以陽極氧化附加氧化層(A】2〇3 )等作法皆 亦即 之構 種, 以介 裝置 圖20 單說 性與 5〜1 . 1 司所 真空 此等 金屬 電極 :綜合 選擇 低掃 爲合 上述 或是 屬於 (5) 1300868 現今之-般技術。亦既,掃描線n㈣工層以上之金 層所構成之。 其次,於玻璃基板2之整面,使用PC VD裝置分別 0.3-0.5 // mi m程度的膜厚依序覆蓋作爲閘極絕緣層之 1 S ιΝχ (矽氮化)層3 0,和不含雜質之作爲絕緣閘極型 晶體之通道之第1非晶矽(a 一 Si )層3 1,及作爲保護 道之絕緣層之第2 S i N X層3 2等3種薄膜層,如圖 (b )與圖2 1 ( b )所示,藉由微細加工技術使得閘極 極1 1 A之第2 S 1N X層3 2選擇性地殘留比閘極電極j 寬幅更細作爲3 2 A,而露出第1非晶矽層3 1。 其次,使用相同之PCVD裝置於全面覆以〇.〇5 μ m 度之膜後之包含雜質例如燐之第2非晶矽層3 3之後, 圖20(c)與圖21(c)所示,使用SPT等之真空製膜 置依序覆蓋〇.1 # ni程度之Ti,Cr,Mo等耐金屬薄膜 3 4來作爲耐金屬層,膜厚〇 · 3 // m程度之鋁薄膜層3 5 爲低電阻配線層,膜厚〇 . 1 # m程度之鈦薄膜層3 6作爲 間導電層,藉由微細加工技術,選擇性形成由源極·汲 配線材之此3種薄膜層積3 4 A ’ 3 5 A ’ 3 6所構成之絕緣 極型電晶體之汲極電極2 1,和亦兼作源極電極之信號 1 2。此選擇性圖案之形成,係將用於形成源極·汲極配 之形成之感光性樹脂圖案作爲遮罩,依序蝕刻Ti薄膜 3 6,銘薄膜層3 5,及T i薄膜層3 4之後,去除源極· 極電極]2,21間之第2非晶矽層33,而露出第2 SiNx 同時,在其他領域上亦去除第1非晶矽層3 1, 屬 以 第 電 通 20 電 1 A 程 如 裝 層 作 中 極 閘 線 線 層 汲 層 露 (6) 1300868 出閘極絕緣層3 0而形成的。如此,存在通道之保護層之 第層2 S iNX層3 2 A而自動結束第2非晶矽層3 3之蝕刻, 此種製法稱之爲蝕刻截止製法。 爲使絕緣閘極型電晶體不成爲偏壓(offset )構造, 源極·汲極電極1 2,2 1,係與閘極電極1 1 A —部份(數 μ m )平面性重疊地形成。此重疊具有寄生電容的電性作 用’故越小越好,其通常係以曝光機之對位精密度和光罩 之精密度和玻璃基板之膨脹係數及曝光時之玻璃基板溫度 等所決定,實用之數値最大爲2 // m。 接著,於玻璃基板2之整面,與以閘極絕緣層同樣使 用PCVD裝置,覆蓋作爲透明性絕緣層之膜厚0.3 # m程 度之SiNx層而作爲鈍化(passivation)絕緣層37,如圖 2 0 ( d )與圖2 1 ( d )所示,藉由微細加工技術選擇性去 除鈍化絕緣層3 7,而於汲極電極2 1,形成開口部6 2,和 在畫像顯示部外之領域被形成掃描線1 1之電極端子5之 位置上形成開口部63,和在被形成掃描線1 2之電極端子 6之位置上形成開口部6 4,而露出汲極電極2 1,和掃描 線〗1與信號線1 2之一部份。於積蓄電容線1 6 (將平行 聚集之電極圖案)上,形成開口部6 5而露出積蓄電容線 ]6之一部分。 最後,使用SPT等真空製膜裝置而覆蓋膜厚〇.;[〜〇.2 # m程度之譬如IT 0 (銦錫氧化物)或是1Z 0 (銦鋅氧化 物)來作爲透明導電層,如圖20 ( e )與圖2 ] ( e )所 示,藉由微細加工技術包含開口部6 2而於鈍化絕緣層3 7 -9- 1300868 (7) 上,選擇性形成畫素電極2 2,完成主動基板2。以開口部 63內之露出的掃描線丨〗之一部份作爲電極端子5,以開 口部64內露出之信號線1 2之一部份做爲電極端子6亦 可’如圖所示,包含開口部 63,64而於鈍化絕緣層37 上,選擇性形成由IT 0所形成之電極端子5 A,6 A亦可, 但是通常亦同時形成連接於電極端子5A,6A4間之透明 導電性之短路線4 0。其理由係雖未圖示但藉由使電極端 子5 A,6A與短路線40之間形成爲細長之條紋狀而高電 阻化,可作爲靜電對策用之高電阻。同樣地,包含開口部 6 5而形成往積蓄電容線1 6之電極端子。 當信號線1 2之配線電阻不成問題時,則未必需要由 鋁形成之低電阻配線層3 5,此種情況,若選擇Ci·,Ta , Μ 〇等之耐熱金屬材料時,可單層化源極·汲極配線1 2, 2 1而簡單化。另外,有關絕緣閘極型電晶體之耐熱性, 已詳細記載於先行例之特開平7-74 3 68號公報。同時,於 圖20 ( c )之中,積蓄電容線1 6與汲極電極2 ]中介著閘 極絕緣層3 0而重疊之領域5 0 (左上往右下之斜線),雖 然形成積蓄電容]5,但是於此省略其詳細說明。 以上所敘述之5道光罩製程,雖然省略詳細之描述, 但係屬半導體層之島化工程與接觸形成工程被削減1道χ 程之結果,故當初需要7〜8道程度之工程,亦藉由乾蝕刻 技術之導入,於現今時減少至5道而大幅有助於製程成本 之削減。爲了降低液晶顯示裝置之生產成本,在主動基板 之製作工程降低製程成本,而在面板組裝工程與模組安裝 -10- 1300868 (8) 工程降低構件成本係屬於有效作法一事爲眾所周知之開發 目標。爲了降低製程成本,,亦有採用縮短製程之工程削 減日寸’與廉ί貝的製程開發或替換製程,但在此舉出以4道 光罩製得主動基板之4道光罩製程做爲工程削減之例而加 以說明。4道光罩製程係導入半色調(h a丨f t 〇 η ^ )曝光技術, 而削減照相触刻工程’故圖22乃爲對應於4道光罩製程 之主動基板之單位畫素平面圖,圖23爲表示圖22(e) 之A - A ’,B — B ’及C 一 C ’線之剖面圖。如先前所敘述, 絕緣閘極型晶體現在常使用的有2種,於此採用通道蝕刻 型之絕緣閘極型電晶體。 首先,與5道光罩製程相同,於玻璃基板2之主面上 使用SPT等真空製膜裝置覆蓋膜厚度之第 1金屬層’如圖2 2 ( a )與圖2 3 ( a )所示,藉由細微加 工技術選擇性形成兼作閘極電極1 1 A之掃描線1 1與積蓄 電容線1 6。 其次,於玻璃基板2之全面使用p C v 〇裝置分別依序 覆蓋膜厚之成爲而將成爲閘極絕 緣層之S iN X層3 0,幾乎不含雜質之成爲絕緣閘極型電晶 體之通道之第1非晶矽層3 1,及包雜質之成爲絕緣閘極 型電晶體之源極.汲極之第2非晶矽層3 3等3種薄膜 層。接者,使用S P T等之真空製膜裝置依序覆蓋譬如膜 厚〇 · 1 " m程度之Ti薄膜層3 4作爲〇耐熱金屬層3 5,膜 厚〇 · 3 /i m程度之例如之例如鋁薄膜層3 5作爲低電阻配線 層,膜厚0 . 1 # m程度之例如膜厚0. ] μ m程度之例如Ti -11 - 1300868 (9) 薄膜層3 6作爲中間導電,亦即依序覆蓋源極·汲極配線 材,藉由細微加工技術選擇性形成兼作絕緣閘極型電晶體 之汲極電極2 1和源極電極之信號線1 2,其最大特點係當 形成此選擇圖案時,藉由半色調(halftone)曝光技術,如 圖22 ( b )和圖23 ( b )所示,源極·汲極配線間之通道 形成領域8 0 C (左下往上之斜線部)之膜厚,譬如爲1.5 m,形成比源極·汲極配線形成領域80A,80B之膜厚 3 m更薄之感光性樹脂圖案80A〜80C。 如此之感光性樹脂圖案80 A〜8 0C,於液晶顯示裝置用 基板之製作通常使用正型感光性樹脂,故源極·汲極配線 形成領域80 A,80B爲黑色,亦即,形成Cr薄膜,通道 領域80C爲灰色,譬如形成寬度0.5〜1 μ m程度之線條空 行間隔(Line And Space)之Cr圖案,其他領域爲白色,亦 即,使用去除Cr薄膜之光罩即可。灰色領域因爲曝光機 之解析度不足,故不會成像出線條及空行(Line And S p a c e),且來自光源之對光罩的照射光可透過約一半左 右,故因應於正型感光性樹脂之殘膜特性而可獲得具有如 圖23 ( b )所示之剖面形狀之感光性樹脂圖案80 A〜8 0C。 以上述感光性樹脂圖案80A〜80C作爲遮罩,如圖22 (b)和圖23 ( b)所示,依序蝕刻Ti薄膜層36,A1薄 膜層3 5,Ti薄膜層3 4,第2非晶矽層3 3及第1非晶矽 層3 1,而露出閘極絕緣層3 0之後,如圖2 2 ( c )和圖2 3 (c )所示,藉由氧氣電漿等之灰化手段使得感光性樹脂 圖案80A〜80C之膜厚,譬如從3 v m減少].5 " m以上 1300868 (10) 8 1 A,8 1 B,8 0 C消失而露出通道領域。於此,將削減薄 膜之感光性樹脂圖案80 A〜8 0C作爲遮罩,再次依序蝕刻 源極·汲極配線間(通道形成領域)之T丨薄膜層3 6 A, A】薄膜層3 5 A,T i薄膜層3 4 A,第2非晶矽層3 3 A及第 1非晶矽層3 1 A,第1非晶矽層3 ] A係被蝕刻至殘留 0.0 5〜0 „ 1 // m程度。被稱爲通道蝕刻的理由係如此蝕刻成 爲通道之半導體所形成的。又,於上述氧氣電漿處理上爲 抑制圖案尺寸之向異性最好是增強向異性。其理由將於後 述敘述之。 再者,去除上述感光性樹脂圖案8 1 A,8 1 B之後,5 道光罩製程同樣如圖22 ( d )和圖23 ( d )所示,於玻璃 基板2之全面覆蓋膜厚〇·3 # m程度之SiNx層作爲透明性 之絕緣層,於形成汲極電極2 1和掃描線1 1和信號線1 2 之電極端子5,6被形成之領域分別形成開口部62,63, 6 4 ’而去除開口部內之鈍化絕緣層3 7與閘極絕緣層3 0。 最後,使用SPT等之真空製膜裝置覆蓋膜厚0.1〜0.2 μ ηι程度之譬如I τ 0或IZ 0來作爲透明導電層,如2 2 (e )和圖2 3(e)所示,藉由微細加工技術使得在鈍化 絕緣層3 7上,包含開口部6 2選擇性形成透明導電性之畫 素電極22而完成主動基板2關於電極端子,在此包含開 口部63,64而於鈍化絕緣層37上選擇性形成由ITO所形 成之電極端子5 A,6 A。 如此,於5道光罩製程與4道光罩製程中,由於通往 汲極電極2 1與掃描線1 1之接觸孔形成工程同時進行,故 -13- 1300868 (11) 對應於此等之開口部62,63內之絕緣層厚度與種類相 異。鈍化絕緣層3 7比閘極絕緣層3 0之製膜溫度較低且膜 質惡劣,於藉由氟酸係氧之蝕刻液蝕刻時,蝕刻速度分別 爲數千埃(A )/分與數百埃(A )/分,相差一個數量級, 汲極電極2 1上之開口部6 2之剖面形狀,由於上部產生過 度蝕刻而無法控制孔徑,故採行利用氟系氣體之乾式蝕刻 (乾蝕刻)。 即使採用乾蝕刻,汲極電極2 1上之開口部62,由於 僅爲鈍化絕緣層3 7,故相較於掃描線之開口部6 3,無法 避免過度蝕刻,隨著材質不同,中間導電層3 6 A有時會 因蝕刻氣體而削薄。此外,當蝕刻結束後之去除感光性樹 脂圖案時,首先爲了去除被氟化的表面之聚合物,以氧氣 電漿灰化將感光性樹脂圖案之表面削減 〇 . 1〜〇 . 3 // m程 度,其後,一般使用有機剝離液,譬如東京應化公司製造 之剝離液106等之藥液處理,但是當中間導電層36A被 削薄而露出基底鋁層3 5 A之狀態時,以氧氣電漿灰化處 理而在鋁層35A之表面形成絕緣體之Al2〇3,在與畫素電 極2 2之間將無法獲得歐姆接觸。於是,爲了使中間導電 層36A即使膜厚削減亦無礙,其膜厚譬如設定成0.2 A m 之較厚的膜厚以避免此問題。或者,形成開口部62〜6 5 時,去除鋁層35A而從露出基底耐熱金屬層之薄膜層34A 之後再形成畫素電極2 2之迴避問題對策亦可,於此情況 中,有一開始就不需要中間導電層3 6 A之益處。 但是,於前者之對策上,當此等薄膜之膜厚之面內均 -14- 1300868 (12) 勻性不好時,此配合未必會有效作用,此外蝕刻速度之 內均勻性不好時,亦完全相同。於後者之對策上,雖然 須中間導電層3 6 A,但是卻增加去除鋁層3 5 A之工程, 當開口部62之剖面控制不充分時,可能引起畫素電極 之斷線。 另外,於通道蝕刻型之絕緣閘極型電晶體上,通道 域之不含雜質之第1非晶矽層3 1,若不事先覆蓋成較 (於通道蝕刻型通常爲〇. 2 // m以上)時,對玻璃基板 面內均勻性將有很大影響而使得電晶體之特性,特別是 止電流會出現參差不齊的傾向。此事對P C V D之工作率 灰塵產生狀況將予頗大影響,從生產成本之觀點視之亦 非常重要事項。 另用,於4道光罩製程之中所適用之通道形成工程 由於選擇性去除源極·汲極配線1 2,2 1間之源極.汲 配線材和半導體層,故爲決定大幅影響絕緣閘極型電晶 之導通(ON)特性之通道長度(於現今之量產品爲4〜6 m )之工程。此通道長度之變動,由於大幅改變絕緣閘 型電晶體之導通電流値,故通常要求嚴格之製造管理, 是通道長度,亦即左右於半色調(ha】ftone)曝光領域之 案尺寸’受到曝光量(光源強度和光罩之圖案精密度, 其係線條與空行尺寸),感光性樹脂之塗布厚度,感光 樹脂之顯像處理,及於該蝕刻工程之感光性樹脂之膜削 量等多種參數之影響,且,此等諸量之面內均勻性亦彼 相依未必能提高產率且穩定生產,相較於傳統之製造 面 並 且 22 領 厚 之 截 和 爲 5 極 體 β 極 但 圖 尤 性 減 此 管 -15- 1300868 (13) 理,需更嚴格之製造管理,現今仍不能謂之已達高度完成 之水準。尤其通道長度爲6〆m以下時其傾向更爲明顯。 本發明之由於有鑑於現狀而完成之發明,不僅避免共 通於傳統之5道光罩製程或4道光罩製程之接觸孔形成時 之瑕疵,且採用製造誤差容許度較大之半色調(halftone) 曝光技術而實現減少製造工程。同時,實現液晶面板之低 價化,爲了逐漸因應於需求之增加而需要更精心追求製造 工程之削減之必要性是容易理解的,藉由簡化或低成本化 其他主要製造工程之技術,更提高本發明之價値。 【發明內容】 於本發明中,首先係將半色調(halftone)曝光技術適 用於圖案精密度管理較容易之蝕刻停止層之形成工程,與 接觸孔形成工程而實現削減製造工程。其次,爲了僅將源 極·汲極配線有效作成鈍化,乃融合揭示於先行技術之特 開平2-2 16 129號公報之在鋁所形成之源極·汲極配線之 表面形成絕緣層之陽極氧化技術,而實現製程合理化及低 溫化。再將經過合理化之揭示於先行技術之特願平 5 -2 6 8 7 26號公報之畫素電極之形成工程適用於本發明。爲 了更加削減工程,於源極·汲極配線之陽極氧化層形成, 亦採用半色調(halftone)曝光技術而合理化電極端子之保 護層形成工程。 記載於申請專利範圍第1項之絕緣閘極型電晶體,其 特徵係於通道上具有保護絕緣層,以包含由不同於源極· -16- (14) 1300868 汲極配線材之導電性材質所形成之源極配線之電氣連接領 域之一部份而形成之源極·汲極配線上,被形成有感光性 有機絕緣層之底部閘極型之絕緣閘極型電晶體,其感光性

Field of the Invention The present invention relates to a liquid crystal display device having a color image display function, and more particularly to an active liquid crystal display device. [Prior Art] In recent years, the meticulous processing technology has been improved by liquid crystal material technology and high-density mounting technology, and the liquid crystal display device with a diagonal scale of 5 to 50 cm has been widely supplied with TV portraits or various image display machines. In the commercial field. At the same time, color display can be easily realized by forming a color layer of RGB in advance on one of the two glass substrates constituting the liquid crystal panel. Especially in every painting. On the so-called active LCD panel with built-in switching elements, it is guaranteed that images with less crosstalk and faster response and higher contrast can be obtained. Such liquid crystal display devices (liquid crystal panels), although scanning lines 2 00 to 1 0 0 0 are used as scanning lines, grouping the signal lines 3 00 to 1 600 to the most common composition. However, recently, the large screen and high refinement corresponding to an increase in display capacity have been simultaneously performed. Fig. 17 shows a state in which the liquid crystal panel is mounted, and constitutes a transparent insulating substrate which is one of the liquid crystal panels 1. For example, the electrode terminal group 5 for the scanning lines formed on the glass substrate 2 is connected by using a conductive adhesive. A COG (Chip On Glass) method of a semiconductor integrated circuit chip 3 for driving signals or a TCP film (not shown) having a gold-plated or plated solder copper foil (2), for example, using a polyimide film as a base layer 1300868 4 'A mounting means such as a TCP (Package Carrier Package) method in which the electrode terminal group 6 fixed to the signal line is crimped by a suitable adhesive containing a conductive medium, and an electric signal is supplied to the image display portion. Although two types of mounting methods are illustrated at the same time, any one of them can be appropriately selected. 7,8 is a line connecting the pixels in the image display portion at the center of the liquid crystal panel 1 and the electrode terminals 5 and 6 of the scanning lines and the signal lines, and the electrode terminal groups 5 and 6 are not necessarily made of the same conductive material. Composition. 9 is a counter-glass substrate or a color filter of another transparent insulating substrate having a counter electrode having transparent conductivity common to all liquid crystal cells on the opposite surface. Fig. 1 is an equivalent circuit diagram showing an active liquid crystal display device in which an insulating gate type transistor 1 is disposed per pixel as a switching element, and 1 1 (7 in Fig. 17) is a scanning line, 12 (8 in Figure 1) is the signal line '1 3 is the liquid crystal single 兀' liquid crystal single 兀 1 3 is considered as a capacitive element on the circuit. The components drawn by the solid line are formed on the glass substrate 2 constituting one of the liquid crystal panels, and the counter electrode 14 common to all the liquid crystal cells 13 drawn by broken lines is formed on the other glass substrate 9. On the opposite side of the main. In the case where the OFF resistance of the insulating gate type transistor 1 or the resistance of the liquid crystal cell 13 is low or the gray scale of the image is emphasized, it is increased. . The auxiliary capacitor 1 5 as the time constant of the liquid crystal cell 13 of the load is improved in parallel with the circuit such as the liquid crystal unit 13 . Fig. 19 is a key sectional view showing an image display portion of the liquid crystal display device, and two glass substrates 2, 9 constituting the liquid crystal panel 1 are formed of a resin - 5 - 1300868 (3) fiber 'bead or colored A spacer (not shown) such as a columnar spacer on the filter 9 is formed at a predetermined distance of a distance of #m, and the gap (interval) is formed on the peripheral portion of the glass substrate 9. The sealing material and the sealing material (not shown) made of the organic resin form a sealed closed space, and the closed space is filled with the liquid crystal 17 . When the color display is realized, the closed space of the glass substrate 9 covers an organic film having a thickness of 1 to 2 " m of any one or both of the dyes or pigments of the colored layer 18, and provides a color display function, in this case The glass substrate 9 is also referred to as a color filter (abbreviated as CF). Further, depending on the nature of the liquid crystal material 17, a polarizing plate is attached to either the upper surface of the glass substrate 9 or the lower surface of the glass substrate 2, or the liquid crystal panel 1 is attached as a photovoltaic element. Features. At present, most of the liquid crystal panels sold on the market use TN (Twisted Nematic) liquid crystal, and the polarizing plate 19 usually requires two. Although not shown, the transmissive liquid crystal panel is provided with a back light source as a light source to illuminate white light from below. Connected to the liquid crystal 17 and formed on the two glass substrates 2, 9 such as thickness 〇.  The polyimine film 20 of 1 / m level is used to align the liquid crystal molecules with the alignment film which determines the direction. 2 1 is a drain electrode (wiring) connecting the gate electrode of the insulating gate type transistor 10 and the transparent conductive pixel 22, and is formed at the same time as the signal line (source line) 12. Located between the signal line 1 2 and the drain electrode 2 1 is a semiconductor layer 23, which will be described in detail later. The thickness formed on the color filter 9 is formed at the boundary of the adjacent color layer 18. The C r thin film layer of 4 V m is a so-called black matrix of a light shielding member for preventing external light from entering the semi--6 - (4) 1300868 conductor layer 2 3 and the scanning line 1 1 and the signal line 1 2 Referred to as Β Μ ) is a customary technology. Here, as a switching element, an insulating gate type transistor fabrication and manufacturing method will be described. At present, one of the commonly used insulating gate type transistors is one of them as a conventional example (referred to as an etch-off type). Figure 20 is a plan view showing a unit pixel of an active substrate (display semiconductor device) constituting a conventional liquid crystal panel, and Figure 21 is a cross-sectional view showing (e) A - A, Β - Β ' and C - C, The following is a brief description of its manufacturing process. First, as shown in Fig. 20 (a) and Fig. 2 1 (a), the thickness 选用 is selected as an insulating substrate having high heat resistance and chemical resistance and high transparency.  The glass substrate 2 of the μ m degree, for example, on the main surface of the product name 1 7 3 7 manufactured by Corning CORNING, is selectively formed by a film forming apparatus such as SPT (sputtering), such as Cr, Ta, Mo, or the like. Covering alloy or metal ruthenium compound film thickness 〇·1~〇. The first layer of the 3#m level, and by the microfabrication technique, selectively forms the scan line 1 1 and the storage capacitor line 16 which also serve as the gate 1 1 A. The material of the scanning line is preferably selected in consideration of heat resistance and chemical resistance, and resistance to fluorine acidity and conductivity. In order to correspond to the large screen or high-definition of the liquid crystal panel, the resistance of the P-line is determined by using aluminum as the material of the scanning line, but the aluminum is in a single state, because the heat resistance is relatively low, Laminated heat resistant metal such as Cl. , Ta, Mo or these metal ruthenium compounds, on the surface of the anodized additional oxide layer (A] 2 〇 3), etc., so that the device is shown in Figure 20 single and 5~1 .  1 Division Vacuum These metal electrodes: Comprehensive selection Low-scan is the above or belongs to (5) 1300868. Also, the scanning layer n (four) is formed by a gold layer above the working layer. Next, on the entire surface of the glass substrate 2, PC VD devices are used respectively. 3-0. The film thickness of 5 // mi m sequentially covers the 1 S Νχ (矽 矽) layer 30 as the gate insulating layer, and the first amorphous 矽 which is the channel of the insulating gate type crystal without impurities ( a -Si) layer 3 1, and a second thin film layer such as the second S i NX layer 3 2 as an insulating layer of the protective track, as shown in (b) and FIG. 2 1 (b), by microfabrication technology The second S 1N X layer 3 2 of the gate electrode 1 1 A is selectively left to be thinner than the gate electrode j as 3 2 A, and the first amorphous germanium layer 31 is exposed. Secondly, the same PCVD device is used to cover the entire surface. After the film having a thickness of 5 μm, including the second amorphous germanium layer 3 3 such as germanium, as shown in Fig. 20 (c) and Fig. 21 (c), the vacuum film forming using SPT or the like is sequentially covered. . 1 # ni degree of Ti, Cr, Mo and other metal-resistant films 3 4 as a metal-resistant layer, film thickness 〇 · 3 / m degree of aluminum film layer 3 5 is a low-resistance wiring layer, film thickness 〇.  The titanium film layer 3 of 1 #m is used as an interlayer conductive layer, and the three kinds of thin film layers 3 4 A ' 3 5 A ' 3 6 of the source/germanium wiring material are selectively formed by microfabrication technology. The drain electrode 2 1 of the insulating pole type transistor and the signal 1 2 also serves as the source electrode. The selective pattern is formed by using a photosensitive resin pattern for forming a source/drain electrode as a mask, and sequentially etching the Ti film 36, the film layer 35, and the film layer 3 of the Ti film. Thereafter, the second amorphous germanium layer 33 between the source and the electrode 2 and 21 is removed to expose the second SiNx, and the first amorphous germanium layer 3 1 is removed in other fields. 1 A process such as layering for the middle pole line layer layer layer exposed (6) 1300868 gate insulator layer 30 formed. Thus, the etching of the second amorphous germanium layer 3 3 is automatically completed by the first layer 2 S iNX layer 3 2 A of the protective layer of the channel. This method is called an etch-off method. In order to prevent the insulating gate type transistor from becoming an offset structure, the source/drain electrodes 1 2, 2 1 are formed in a planar manner overlapping with the gate electrode 1 1 A (several μ μm). . This overlap has an electrical effect of parasitic capacitance', so the smaller the better, it is usually determined by the alignment precision of the exposure machine and the precision of the mask, the expansion coefficient of the glass substrate, and the temperature of the glass substrate during exposure. The maximum number is 2 // m. Next, on the entire surface of the glass substrate 2, a PCVD apparatus was used in the same manner as the gate insulating layer, and the film thickness as a transparent insulating layer was covered. The SiNx layer of 3 #m is used as a passivation insulating layer 37, as shown in Fig. 20 (d) and Fig. 2 1 (d), by selectively removing the passivation insulating layer 3 by microfabrication technique. The gate electrode 2 1 is formed with an opening portion 6 2, and an opening portion 63 is formed at a position where the electrode terminal 5 of the scanning line 11 is formed outside the image display portion, and the electrode terminal 6 at which the scanning line 12 is formed The opening portion 64 is formed at a position to expose the drain electrode 2 1, and a portion of the scanning line 1 and the signal line 1 2 . On the storage capacitor line 16 (electrode pattern to be collected in parallel), an opening portion 65 is formed to expose one of the storage capacitor lines 6.5. Finally, a vacuum film forming apparatus such as SPT is used to cover the film thickness. ;[~〇. 2 # m degree such as IT 0 (indium tin oxide) or 1Z 0 (indium zinc oxide) as a transparent conductive layer, as shown in Figure 20 (e) and Figure 2 (e), by microfabrication The technique includes an opening portion 6 2 and a passivation insulating layer 3 7 -9- 1300868 (7) to selectively form the pixel electrode 2 2 to complete the active substrate 2. One portion of the exposed scanning line in the opening portion 63 is used as the electrode terminal 5, and a portion of the signal line 1 2 exposed in the opening portion 64 is used as the electrode terminal 6 as shown in the figure. The opening portions 63, 64 are formed on the passivation insulating layer 37, and the electrode terminals 5 A, 6 A formed by IT 0 are selectively formed, but generally, the transparent conductivity between the electrode terminals 5A, 6A4 is also formed at the same time. Short circuit 4 0. The reason for this is that the electrode terminals 5 A, 6A and the short-circuit line 40 are formed in a stripe shape and are highly resistive, although they are not shown, and can be used as a high resistance for static electricity countermeasures. Similarly, the electrode portion of the storage capacitor line 16 is formed by including the opening portion 65. When the wiring resistance of the signal line 12 is not a problem, the low-resistance wiring layer 35 formed of aluminum is not necessarily required. In this case, if a heat-resistant metal material such as Ci, Ta, Μ or the like is selected, it can be single-layered. The source and drain wirings 1 2, 2 1 are simplified. Further, the heat resistance of the insulated gate type transistor has been described in detail in Japanese Laid-Open Patent Publication No. Hei 7-74 3 68. Meanwhile, in FIG. 20(c), the storage capacitor line 16 and the drain electrode 2 are interposed by the gate insulating layer 30 and overlap the field 50 (the upper left to the lower right oblique line), although the storage capacitor is formed] 5, but the detailed description thereof is omitted here. The five mask processes described above, although the detailed description is omitted, are the result of a one-way reduction of the islanding project and the contact formation project of the semiconductor layer. Therefore, the project of 7 to 8 degrees was originally required. The introduction of dry etching technology has been reduced to five lanes today, which has greatly contributed to the reduction of process costs. In order to reduce the production cost of the liquid crystal display device, the manufacturing process of the active substrate reduces the process cost, and in the panel assembly engineering and module installation -10- 1300868 (8) The reduction of component cost is an effective development practice. In order to reduce the cost of the process, there are also process development or replacement processes that use the process of shortening the process to reduce the size of the process and the production process. However, the four mask processes of the active substrate with four masks are used as engineering reductions. Explain by way of example. The four-mask process introduces a halftone (ha丨ft 〇η ^ ) exposure technique and reduces the photo-touching process. Therefore, Figure 22 is a plan view of the unit pixel corresponding to the active substrate of the four-mask process. Figure 23 shows Figure 22(e) is a cross-sectional view taken along line A - A ', B - B ' and C - C '. As described earlier, there are two types of insulating gate type crystals which are commonly used, and a channel-etch type insulating gate type transistor is used here. First, as in the case of the five mask processes, the first metal layer of the film thickness is covered on the main surface of the glass substrate 2 by using a vacuum film forming apparatus such as SPT, as shown in Fig. 22 (a) and Fig. 23 (a). The scanning line 1 1 serving as the gate electrode 1 1 A and the storage capacitor line 16 are selectively formed by a micromachining technique. Next, in the entire glass substrate 2, the p C v 〇 device is used to sequentially cover the thickness of the film, and the S iN X layer 30 which becomes the gate insulating layer is almost free of impurities and becomes an insulating gate type transistor. The first amorphous germanium layer 3 1 of the channel and the impurity of the impurity become the source of the insulating gate type transistor. Three kinds of thin film layers such as the second amorphous germanium layer 3 3 of the bungee. Then, a vacuum film forming apparatus such as SPT is used to sequentially cover, for example, a film thickness 〇 1 " m of the Ti film layer 34 as a ruthenium metal layer 35, and a film thickness 〇 · 3 /im degree, for example, for example The aluminum thin film layer 35 is used as a low resistance wiring layer and has a film thickness of 0.  1 # m degree, for example, film thickness 0.  ] μ m degree, for example, Ti -11 - 1300868 (9) The thin film layer 36 is used as an intermediate conductive, that is, sequentially covering the source and drain wiring materials, and selectively forms an insulating gate type transistor by a microfabrication technique. The signal line 12 of the drain electrode 2 1 and the source electrode is characterized by a halftone exposure technique when forming the selection pattern, as shown in FIGS. 22(b) and 23(b). It is shown that the channel thickness of the channel between the source and the drain wiring is 80 C (the lower left oblique line), for example, 1. 5 m, photosensitive resin patterns 80A to 80C which are thinner than the source/drain wiring formation areas 80A and 80B and having a film thickness of 3 m are formed. In the photosensitive resin patterns 80 A to 80C, the positive photosensitive resin is usually used for the production of the substrate for a liquid crystal display device. Therefore, the source/drain wiring formation regions 80 A and 80B are black, that is, the Cr film is formed. The channel area 80C is gray, such as forming a width of 0. The line pattern of the line and space of 5 to 1 μm is white, and the other areas are white, that is, the mask for removing the Cr film can be used. In the gray field, because the resolution of the exposure machine is insufficient, the line and S pace are not imaged, and the illumination light from the light source to the reticle can be transmitted through about half, so it is suitable for the positive photosensitive resin. The photosensitive resin patterns 80 A to 80C having the cross-sectional shape as shown in Fig. 23 (b) can be obtained by the residual film characteristics. The photosensitive resin patterns 80A to 80C are used as masks, and as shown in FIGS. 22(b) and 23(b), the Ti thin film layer 36, the A1 thin film layer 35, and the Ti thin film layer 34 are sequentially etched. After the amorphous germanium layer 3 3 and the first amorphous germanium layer 3 1 are exposed to the gate insulating layer 30, as shown in FIG. 22 (c) and FIG. 23 (c), by oxygen plasma or the like The ashing means makes the film thickness of the photosensitive resin patterns 80A to 80C, for example, from 3 vm]. 5 " m or more 1300868 (10) 8 1 A, 8 1 B, 8 0 C disappears to reveal the channel area. Here, the photosensitive resin patterns 80 A to 80C of the film are reduced as a mask, and the T丨 film layer 3 6 A of the source/drain wiring line (channel formation region) is sequentially etched again, and the film layer 3 is formed. 5 A, T i thin film layer 3 4 A, second amorphous germanium layer 3 3 A and first amorphous germanium layer 3 1 A, first amorphous germanium layer 3 ] A is etched to residual 0. 0 5~0 „ 1 // m degree. The reason for the channel etching is formed by etching the semiconductor into the channel. In addition, it is preferable to suppress the anisotropy of the pattern size in the above oxygen plasma treatment. The reason for this will be described later. Further, after removing the photosensitive resin patterns 8 1 A, 8 1 B, the five mask processes are also shown in Fig. 22 (d) and Fig. 23 (d), in the glass. The SiNx layer of the substrate 2 having a total thickness of #·3 # m is used as a transparent insulating layer, and the electrode terminals 5 and 6 forming the gate electrode 2 1 and the scanning line 1 1 and the signal line 1 2 are formed. The opening portions 62, 63, 6 4 ' are respectively formed to remove the passivation insulating layer 37 and the gate insulating layer 30 in the opening portion. Finally, the film thickness is covered by a vacuum film forming apparatus such as SPT. 1~0. 2 μ ηι degree such as I τ 0 or IZ 0 as a transparent conductive layer, as shown in 2 2 (e ) and FIG. 23 (e), the micro-processing technique is used to include an opening in the passivation insulating layer 37 The portion 6 2 selectively forms the transparent conductive pixel electrode 22 to complete the active substrate 2 with respect to the electrode terminal, and includes openings 63 and 64 therein to selectively form the electrode terminal 5 A formed of ITO on the passivation insulating layer 37. , 6 A. Thus, in the five mask process and the four mask process, since the contact hole forming process of the gate electrode 2 1 and the scanning line 11 is simultaneously performed, 13-1300868 (11) corresponds to the opening portion of the same. The thickness of the insulation layer in 62, 63 is different from the type. The passivation insulating layer 37 has a lower film forming temperature than the gate insulating layer 30 and has a poor film quality. When etching by a fluoric acid-based oxygen etching solution, the etching rate is several thousand angstroms (A)/minute and several hundreds, respectively. An angstrom (A)/min, which differs by an order of magnitude, and the cross-sectional shape of the opening portion 6 2 on the drain electrode 2 1 cannot be controlled by excessive etching of the upper portion, so dry etching using a fluorine-based gas (dry etching) is employed. . Even if the dry etching is used, since the opening portion 62 of the drain electrode 2 1 is only the passivation insulating layer 3 7, the overetching cannot be avoided compared to the opening portion 63 of the scanning line, and the intermediate conductive layer is different depending on the material. 3 6 A is sometimes thinned by etching gas. Further, when the photosensitive resin pattern is removed after the etching is completed, first, in order to remove the polymer of the surface to be fluorinated, the surface of the photosensitive resin pattern is reduced by oxygen plasma ashing.  1~〇.  3 / m degree, after that, generally, an organic stripping liquid, such as a liquid stripping liquid 106 manufactured by Tokyo Yinghua Co., Ltd., is used, but when the intermediate conductive layer 36A is thinned to expose the base aluminum layer 3 5 A At the time, Al2〇3 which forms an insulator on the surface of the aluminum layer 35A by oxygen plasma ashing treatment cannot obtain an ohmic contact with the pixel electrode 22. Therefore, in order to make the intermediate conductive layer 36A even if the film thickness is reduced, the film thickness is set to 0. A thick film thickness of 2 A m to avoid this problem. Alternatively, when the openings 62 to 6 5 are formed, the aluminum layer 35A may be removed, and the mask electrode 2 may be removed from the thin film layer 34A of the underlying heat resistant metal layer, and the countermeasure may be avoided. In this case, there is no The benefit of the intermediate conductive layer 3 6 A is required. However, in the countermeasures of the former, when the film thickness of these films is 14-1300868 (12), the uniformity is not good, and when the uniformity within the etching rate is not good, It is also identical. In the latter countermeasure, although the intermediate conductive layer 3 6 A is required, the process of removing the aluminum layer 35 A is increased, and when the cross-section control of the opening portion 62 is insufficient, the pixel electrode may be broken. In addition, on the channel-etched insulating gate type transistor, the first amorphous germanium layer 3 1 containing no impurities in the channel region is not covered in advance (the channel etching type is usually 〇.  When 2 / m or more, the in-plane uniformity of the glass substrate is greatly affected, so that the characteristics of the transistor, particularly the current holding current, tend to be jagged. This matter will have a considerable impact on the working rate of P C V D dust, which is also very important from the point of view of production cost. In addition, the channel formation process applied in the 4-mask process is due to the selective removal of the source of the source/drain wiring 1 2, 2 1 . 配线 The wiring material and the semiconductor layer are the projects that determine the channel length (4 to 6 m in current quantities) that greatly affects the ON (ON) characteristics of the insulated gate type. The change in the length of this channel, due to the large change in the on-state current of the insulating gate transistor, usually requires strict manufacturing management, which is the channel length, that is, the size of the exposure in the field of halftone (ha]ftone). The amount (the intensity of the light source and the pattern precision of the mask, the line and the blank line size), the coating thickness of the photosensitive resin, the development processing of the photosensitive resin, and the film thickness of the photosensitive resin in the etching process, and the like The influence of the in-plane uniformity of these quantities may not be able to improve the yield and stabilize the production, compared to the conventional manufacturing surface and the cross-section of the 22-thickness is the 5 pole body β pole but the figure is Reducing this pipe -15- 1300868 (13) requires more stringent manufacturing management, and it is still not a high level of completion. Especially when the channel length is less than 6〆m, the tendency is more obvious. The invention has been completed in view of the present situation, and not only avoids flaws in the formation of contact holes common to the conventional five-mask process or four-mask process, but also employs a halftone exposure with a large manufacturing tolerance. Technology to achieve reduced manufacturing engineering. At the same time, in order to reduce the cost of liquid crystal panels, it is easy to understand the need to more carefully pursue the reduction of manufacturing engineering in response to the increase in demand. By simplifying or reducing the cost of other major manufacturing engineering technologies, The price of the present invention.

[Embodiment] An embodiment of the present invention will be described based on Figs. 1 to 16 . 1 is a plan view showing a semiconductor device (active substrate) for a display device according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a manufacturing process of AA, line, and BB, line and C-C' line of FIG. . Similarly, in the second embodiment, the third embodiment, the fourth embodiment, the fifth embodiment, the sixth embodiment, and the seventh embodiment, FIG. 3 and FIG. 4, FIG. 5 and FIG. 6, FIG. 8 and FIG. 9 and FIG. 11 and FIG. 12, FIG. 13 and FIG. 12, FIG. 15 and FIG. 16 are sectional views showing a plan view and a manufacturing process of the active substrate. Further, the same portions are denoted by the same reference numerals, and the detailed description thereof will be omitted. (First embodiment) A first embodiment of the present invention will be described. In the first embodiment, the same as the previous example, first, as shown in Fig. 1 (a) and Fig. 2 (a), a small vacuum is formed on the main surface of the glass substrate 2 by using SPT (sputtering) or the like. Zhuang, such as c〗, Ta, Mo, etc. or covering these alloys or metal ruthenium compounds to form a film thickness ] ·] ~ 0 · 3 degrees m of the metal layer, by -34 - 1300868 (32) The micromachining technique selectively forms a scan line J] which serves as both the gate electrode 1 1 A and a common capacitance line 16 . A more detailed description will be described in detail later, and in the present invention, the scanning line material will be almost unlimited. Next, in the entire glass substrate 2, a PCVD apparatus is used to sequentially cover, for example, a film thickness 〇·3 // m which will become the first s丨n X (germanium nitride) layer 30 of the gate insulating layer, and a film. Thickness 〇 · 5 // m degree, which is almost free of impurities and becomes the first amorphous germanium (a - S i ) layer 3 1, which is the channel of the insulating gate type transistor, and the film thickness is 0 · 1 // m Three kinds of thin film layers of the second SiNx layer 31 which are the insulating layers of the protection channel, and as shown in FIG. 1(b) and FIG. 2(b), in the field outside the image display portion, the electrodes of the scanning line 1 1 In the field of terminal formation, an opening portion 63 A is formed by a halftone exposure technique (an opening portion 6 5 a in the field of forming an electrode terminal of the common capacitance line 16), and at the same time, a protective insulating layer is formed, that is, a gate The film thickness of the field 8 2 A on the electrode 1 1 A is, for example, a photosensitive resin pattern 8 2 A, 8 2 B which is thicker than 2 / 4 m of other fields 8 2 B. Selectively removing the second SiNx layer 32 of the channel protective layer in the opening portion 63A (and the opening portion 65A) and the first amorphous germanium layer 3 and the gate with the photosensitive resin patterns 82A and 82B as masks The edge of the first layer 1 S i N X layer 30 to expose the scanning line] 1 (and the common capacitance line 16), one part 72. The pitch of the electrode terminals of the scanning line 1 is at most half of the electrode gap of the driving LSI, and since it is usually 20 0 / m or more, the fabrication of the mask for forming the opening portion 6 3 A (white area) is performed. And the precision management of the finished size is extremely easy. When the photosensitive resin-35-1300868 (33) pattern 82 A, 82B is reduced by a thickness of 1 // m or more by ashing means such as oxidizing plasma, the photosensitive resin pattern 82B disappears, as shown in the figure ( c) As shown in Fig. 2(c), while the second SiNx layer 32 is exposed, the photosensitive resin pattern 8 2 C can be selectively formed only in the field of protective insulating layer formation. Further, in the above oxygen plasma treatment, it is preferable to control the pattern size change to enhance the anisotropy, but it is not necessary when the pattern precision is low. The photosensitive resin pattern 8 2 C, that is, the pattern width of the etch-off layer is the size between the source and the drain wiring, and the precision of the reticle is matched, so the source/drain wiring is 4~ 6 am, and the precision of the fit is ± 3 // m, the dimensional precision is 1 0~1 2 // m, and the dimensional precision requirements are not strict. However, when the resist pattern is converted to 82 C, the photoresist pattern is uniformly and uniformly reduced by 1 // m, and the size is not only reduced by 2 # m, but also the precision of the mask when the source/drain wiring is formed. The reduction to 1 // m becomes ± 2 // m, which is more stringent than the former. Therefore, in the above oxygen plasma treatment, in order to control the change in the size of the pattern, it is preferable to enhance the anisotropy. Specifically, it is preferably an RIE (Reactive Ion Etching) method, or an ICP (Inductive Coupled Plasam a) method or a TCP (Transfer Coupled Plasam a) method having a high density plasma source. Plasma treatment is better. As shown in Fig. 1 (d) and Fig. 2 (d), the second SiNx layer 32 is etched to the gate electrode 11A by the photosensitive resin pattern 82C as a mask, and becomes a second SiNx layer. 3 2 A, at the same time, the first amorphous sand layer 31 is exposed. The field of protective insulating layer formation, that is, the size of the photosensitive resin pattern 8 2 C (black field), even the smallest size, I 〇Μ (7) size, the black field and the white field - 36-1300868 (34) field As a halftone exposure field, not only is the mask fabrication easier, but also compared to the channel-etched insulating gate transistor, the channel protection insulating layer 3 2 A is determined by the starting current of the insulating gate transistor. Dimensions, not the dimensions of the source and drain wirings 12, 2, make process management easier. Specifically, for example, the source of the channel etching type. The size of the drain wiring is 5 ± 1 // m, and the size of the protective insulating layer for the etch stop type is 10 ± 1 // m. Under the same development conditions, the variation of the on-current is approximately halved. At this time, a portion of the exposed scanning line 1 1 is exposed to the etching gas or the chemical of the protective insulating layer 3 2 A, so that the material of the scanning line n is different. In the case where, for example, the aluminum alloy is exposed, if Ti is selected as the source/drain wiring material in the lowermost layer, the influence of oxidation can be easily avoided. Others, as explained in the previous examples, for example, the scanning line 11 is previously formed as a laminate of aluminum/titanium/aluminum. Even if the titanium of the upper layer disappears, the aluminum may be removed to expose the titanium of the lower layer. After the removal of the photosensitive resin pattern 82C, the PCVD device is used on the entire surface of the glass plate 2, for example, at 0. Film thickness coverage of 0 5 # m 譬 After the second amorphous germanium layer 33 containing phosphorus as an impurity, a vacuum film forming apparatus such as SPT is used to sequentially cover a film thickness of 0.  1 #m degree as an anodized heat-resistant metal layer of Ti, Ta and other heat-resistant metal film layer 34; and film thickness of 0. The same level of 3 m is used as the aluminum film layer 3 5 of the anodizable low resistance wiring layer; and the film thickness is 0.  1 / m is the same as the heat-resistant metal thin film layer 36 such as Ta which can be anodized intermediate conductive layer. Then, the source/drain wiring material composed of the three-layer thin film and the second amorphous germanium layer 3 are sequentially etched by a micro-machining technique using a photosensitive resin pattern-37-1300868 (35). 3 and the first amorphous germanium layer 3 1, exposing the gate insulating layer 30, as shown in Fig. (e) and Fig. 2(e), selectively formed by lamination 3 4 A, 3 5 A, 3 The drain electrode 2 1 of the insulated gate type transistor formed by 6 A and the signal line 12 which also serves as the source. Further, in general, when the source/drain wirings 1 2, 2 1 are formed, the scanning line electrode terminals 5 are simultaneously formed in one portion of the scanning lines, but the materials of the source and the drain are different. There is also the possibility that the electrode terminals are not formed here as shown in the figure. If the limitation of the resistance 値 is loose, the structure of the source/drain wiring 1 2, 2 1 can be simplified to form a Ta single layer, and the chemical potential of the aluminum alloy to which Nd is added is lowered in the alkaline solution. The chemical corrosion reaction with ITO is suppressed. Therefore, the intermediate conductive layer 36 can be used to form a two-layer structure and source of the source/drain wiring 1 2, 2 1 without the intermediate conductive layer 36. The structure of the bungee wiring 1 2, 2 1 is somewhat simplified. After the source/drain wiring 1 2, 2 1 is formed, the glass substrate 2 is covered with a vacuum film forming apparatus such as SPT, such as ITO. 1~0. a transparent conductive layer of a degree of β m, as shown in Fig. 1 (f) and Fig. 2 (f), by means of a micromachining technique, a portion of the intermediate conductive layer 3 6 A including the drain electrode 2] is gated The pixel electrode 22 is selectively formed on the pole insulating layer 30. At this time, a transparent conductive film is formed on one of the scanning line portions 7 2 (or the electrode terminal 5) and the signal line 1 2 outside the image display portion to become the transparent conductive electrode terminals 5 A, 6 A. In addition, similarly to the short-circuit line 40 in which the transparent conductivity is provided from the previous example, the electrode terminals 5 A, 6 A and the short-circuit line 40 are formed in a long strip shape to increase the resistance, and it is easy to be static - 38- 1300868 (36) High resistance for electric countermeasures. Next, as shown in Fig. 1 (g) and Fig. 2 (g), the photosensitive resin pattern 83 for selectively forming the pattern of the pixel electrode 22 is used as a light mask, and the light is irradiated while anodizing the source and the drain Wiring 2, 2 1 forms an oxide layer on the surface. Ta is exposed on the upper surface of the source/drain wiring 1 2, 2 1 , and Ta, Al, Ti, and a layer of the second amorphous germanium layer 33A and the first amorphous germanium layer 3 ] A are exposed on the side surface. The anodic oxidation causes the second amorphous germanium layer 33A to be deteriorated into an impurity-containing yttrium oxide layer (SiO 2 ) 66 to deteriorate the first amorphous germanium layer 31 A into an impurity-free yttrium oxide layer (Si 02 ) 67. Ti is metamorphosed into titanium oxide (Ti02) 6.8 which is a semiconductor, and alumina (AL203) 69 which deteriorates AL into an insulating layer, and Ta is deteriorated into molybdenum pentoxide (Ta205) 70 in an insulating layer. Although the titanium oxide layer 68 is not an insulating layer, its film thickness is extremely thin and the exposed area is small. Therefore, in principle, the passivation is not problematic, but it is preferable that the heat-resistant metal thin film layer 34A is Ta selected in advance. However, since Ta is different from Ti, it lacks the surface oxide layer of the absorbing substrate, so that the characteristics of the ohmic contact function are brought to the attention. In the gate wiring 2 1 , in order to form an anodized layer of a good film quality, anodization is performed while irradiating light, which is an important point of the anodizing process and has been disclosed in the prior art. Specifically, if the leakage current of the insulating gate type transistor is more than /A when the light of the 10,000 lux is sufficiently strong, and the leakage current of the insulating gate type transistor is more than /A, it is calculated from the area of the drain electrode 2 1 , 1 〇 m / Anodizing to the extent of cm2 is the current density at which a good film quality can be obtained. However, even if the film quality of the anodized layer on the drain wiring 2 1 is insufficient, generally, sufficient reliability can be obtained, and the reason is that the driving signal applied to the liquid crystal single-39-1300868 (37) element is basically The upper side is an alternating current, so that the voltage of the counter electrode I 4 is adjusted during the image inspection in such a manner that the DC voltage component between the counter electrode 14 and the pixel electrode 2 2 (the drain electrode 2 1 ) is reduced (the flicker adjustment is lowered). In the basic principle, the insulating layer may be formed in advance so that only the DC component current is not present on the signal line 12.

Finally, the photosensitive resin pattern 8 3 is removed, and as shown in Fig. 1 (h) and Fig. 2 (h), the active substrate 2 (display device semiconductor device) is completed. The active substrate 2 and the color filter thus obtained are liquid crystal panelized, and the first embodiment of the present invention is completed. As shown in Fig. (h), the accumulated capacitance is displayed as shown in Fig. (h), and the pixel electrode 2 2 - 40 - 1300868 (38) The spacer gate insulating layer 30 is planarly overlapped (top left) In the example of the lower right part, the structure of the storage capacitor 15 is not limited, and the structure of the insulating layer of the interposer insulating layer 30 may be between the pixel electrode 22 and the front scanning line 亦可. . In addition, other configurations are possible, but the description thereof is omitted. Similarly, since there is a connection forming process to the scanning line, it is easy to perform electrostatic countermeasures by using a conductive material or a half layer other than the transparent conductive layer. In the first embodiment, the layer of the low-precision precision is formed in the contact hole forming the trace protection layer (etching stop layer or protective insulating layer) in the contact hole of the scanning line, and a halftone exposure technique is applied to the photolithography process. The active substrate is formed by four masks. However, the formation of the pixel electrode and the scanning line can be processed by one mask, and the active substrate can be fabricated by using three masks.

1300868 (42) 案8 5並非採用以酚酸淸樹脂爲主要成分之普通感光性植寸 月旨,而是使用純度局,主成分使用含聚丙燒酸樹脂或聚n 亞胺樹脂之耐熱性較高之感光性有機絕緣層是很重要的, 隨材質不同有些可藉由加熱而使流動化,而覆蓋源極.汲 極配線1 2,2 1之側面的方式構成之,此種情況下,更加 改善液晶面板之可信賴性。關於積蓄電容1 5之構成,如 圖3 ( e )所示,以源極·汲極配線1 2,2 1,和包含畫素 電極2 2之一部份所形成之積蓄電極7 3,和設置於前段掃 描線1 1之突起部寺’中介者電發保護層7 1 A,與閘極絕 緣層3 0 A,而平面性重疊之構成已有例示(左上往右下之 斜線部分5 2 ),但積蓄電容1 5之構造並不以此爲限,如 同第1實施形態,於掃描線與同時形成之共通電容線1 6 及畫素電極2 2之間,中介者包含閘極絕緣層3 〇 a之絕緣 層的構成亦可。此外,其他構造亦可,但省略其詳細說 明。 於第2實施形態,掃描線之電極端子和信號線之電極 端子都有必須是透明導電層的裝置構成上的限制,但是, 解除其限制之裝置·製程亦屬可行,將此作爲第3,第4 實施形態而加以說明。 (第3實施形態) 於第3實施形態,如圖5 ( d )和圖6 ( d )所示,到 接觸形成工程和通道保護層(蝕刻截止層)之形成工程, 係以約略爲相问於弟2貫施形態之製程進行之。但是,由 - 45- 1300868 (43) 於後述之理由,未必需要用到擬似電極端子9 4。其後, 去除感光性樹脂圖案84C,使用PVCD裝置而於玻璃基板 2之全面例如以〇 · 〇 5 // m程度之膜厚覆蓋包含雜質例如磷 之第2非晶矽層3 3之後,於源極.汲極配線之形成工程 上,使用S P T等真空製膜裝置,依序覆蓋膜厚〇. 1 " m程 度之譬如Ti’ Ta _耐熱金屬薄膜層34來作爲耐熱金屬 層,膜厚0.3 // m程度之鋁薄膜層3 5作爲低電阻配線層。 接著,此等2層薄膜所構成之源極·汲極配線材,和第2 非晶矽層3 3與第1非晶矽層3 1 B,藉由細微加工技術, 使用感光性樹脂圖案8 6依序蝕刻,而露出閘極絕緣層 3 0 A,如圖5 ( e )與圖6 ( e )所示,選擇性形成含畫素電 極2 2之一部份而由3 4 A和3 5 A之層積所構成的絕緣閘極 型電晶體之汲極電極 2 1,和亦兼作源極配線之信號線 1 2,於形成源極·汲極配線1 2,2 1時,亦同時包含露出 之掃描線電極端子形成領域5A而形成掃描線之電極端子 5與由信號線之一部份所構成之電極端子6。亦即,如第 2實施形態,未必需要用到擬似電極端子94。此時,信號 線1 2上之8 6 A之膜厚,譬如爲3 m,比汲極電極2 1上 與電極端子5,6上,及積蓄電極73上之86B之膜厚1.5 # m還要厚的感光性樹脂圖案 86A,86B藉由半色調 (halftone)曝光技術事先形成,此爲第3實施形態之重要 特徵。對應於電極端子5,6之8 6 B之最小尺寸爲數1十 # m,比較大;光罩製作及製作尺寸管理雖然也極爲容 易,但是由於對應於信號線]2領域8 6 A之最小尺寸爲 1300868 (44) 4〜8 // m ’尺寸精度要求較高,故有必要採用較細間隙之 Η案來作爲半色調(h a 1 f t ο n e)領域。但是,如先前例所說 明的’相較於以1次曝光處理與2次蝕刻處理而形成之源 極·汲極配線1 2,2 1,本發明之源極.汲極配線1 2, 2 1,只要以1次曝光處理與1次蝕刻處理即可形成,故影 響圖案寬度變動之因素較少,且源極·汲極配線1 2,2 1 之尺寸管理,以及源極·汲極配線1 2,2 1間,亦即通道 長度之尺寸管理亦比從前的半色調(halftone)曝光技術更 容易進行圖案精密度之管理。此外,相較於通道蝕刻型之 絕緣閘極電晶體,決定絕緣閘極型電晶體之導通電流的是 通道保護絕緣層3 2 A之尺寸,而非源極·汲極配線1 2, 2 1間之尺寸,故可理解其更易於進行製程管理。 形成源極·汲極配線1 2,2 1之後,藉由氧氣電漿等 灰化手段將上述感光性樹脂圖案8 6 A,8 6B削減膜厚1.5 m以上時,感光性樹脂圖案8 6 B消失,如圖5 ( f)與 圖6 ( f)所示,可於汲極電極2 1與電極端子5,6露出 之同時,僅於信號線1 2上,選擇性形成感光性樹脂圖案 8 6C,以上述氧氣電漿處理使感光性樹脂圖案86C之圖案 寬度變細時,露出信號線1 2之上面而降低可信賴性,故 最好要強化異方性(向異性),抑制圖案尺寸之變化。 又,若電阻値之限制不嚴格時,源極·汲極配線1 2,2 1 之構造可簡化爲Ta,Cr,Mo等之單層。 貼合如此進行所得之主動基板2和彩色濾光片而液晶 面板化,完成本發明之第3實施形態。即使於第3實施形 -47 -

For example, a high melting point metal such as Cr or Ta'Mo or an alloy or a metal ruthenium compound is selected as the first metal layer. The insulator gate insulation layer improves the insulation withstand voltage of the signal line. In order to improve the yield, the electrodes are preferably controlled by dry etch for the slope of the cross-sectional shape, but the dry etching technique of the IT 于 is etched. The technique of using HI (hydrogen iodide) or hydrogen bromide (HBr) for gas has been developed, but the amount of the reaction product in the exhaust system is too large to be put into practical use. Therefore, Ar is currently used. Splashing and etching of (argon) may be used. Secondly, in the whole of the glass substrate 2, to 0.  A film thickness of 1 / m is covered with a transparent insulating layer such as TaOx or SiO 2 as a plasma protective layer. The plasma protective layer 71 is a transparent conductive layer 9 1 A, 9 which is exposed at the margin of the scanning line 1 1 and the pseudo pixel electrode 13 in order to prevent SiNx of the gate insulating layer from being formed by a PC VD device to be described later. 1 B is reduced, and it is necessary to change the film quality of SiNx. For details, refer to the above-mentioned Japanese Patent Laid-Open Publication No. 59-99. After the plasma protective layer 71 is covered, it is the same as that of the first embodiment, and the PCVD apparatus is sequentially formed by 0. 2 ν m-0. 05 // m-0.  1 / m degree film thickness becomes the first S iNx layer 30 of the gate insulating layer, and the first amorphous germanium layer 3 1 ' which becomes a channel of the insulating gate type transistor containing almost no impurities and becomes protection Three kinds of thin film layers, such as the second SiNx layer 32 of the insulating layer of the channel, are formed on the pseudo-pixel electrode 93 in the field of the electrode terminal formation of the scanning line 11 in the field outside the opening portion 7 and the image display portion. It has an opening portion 63 3 A, and has an opening portion 6 4 A on the pseudo electrode terminal 94, and at the same time, a -42-1300868 (40) protective insulating layer forming field, that is, a field on the gate electrode 1 1 A The photosensitive resin pattern 84A, 84B having a film thickness of 8 4 A, such as 2 // m, is thicker than the film of other fields 8 4 B by 1 / 4 m, which is formed by a halftone exposure technique. The gate insulation layer becomes a plasma protective layer. . In combination with the i-SiNx layer, the SiC]nNx can be formed to be thinner than before. The photosensitive resin patterns 8 4 A, 84 B are used as masks, and as shown in FIG. 3 (b) and FIG. 4 (b), the second si NX layer 3 2 in the opening portion is sequentially etched, and the first amorphous germanium is used. The layer 3 1, the gate insulating layer 3, the plasma protective layer 71, and the first metal layer 92, expose a portion of the transparent conductive layer of the scanning line n, and form the electrode terminal 5A of the scanning line, similarly, The electrode terminal 6A which is a signal line is formed by exposing the transparent conductive layer of the electrode terminal 94, and the transparent conductive layer 91B of the pseudo pixel electrode 93 is exposed to form the pixel electrode 22. When the photosensitive resin patterns 84A and 84B are reduced in thickness by 1 m or more by the ashing means such as oxygen plasma, the photosensitive resin pattern 84B is removed, as shown in Fig. 3 (b) and Fig. 4 (b). As shown in the figure, the photosensitive resin pattern 84C can be selectively formed only in the field of formation of the protective insulating layer while exposing the second SiNx layer 3 2B. In the above oxygen plasma treatment, in order not to lower the source as described later. The mask of the bungee wiring forming engineering is matched with the precision, so it is better to enhance the anisotropy (the opposite sex) and suppress the change of the pattern size. As shown in FIG. 3(d) and FIG. 4(d), the second SiNx layer 32B is selectively etched by using the photosensitive resin pattern 84C as a mask to form a thinner pattern than the pattern of the gate electrode HA. The 2SiNx layer 32 A also exposes the first amorphous germanium layer 3 1 B. At this time, the electrode terminal 5A of the transparent conductive scanning line exposed in the opening 63A, and the electrode terminal 6A of the signal line of the 43-1300868 (41) and the pixel electrode 22 are exposed to the etching of the layer 3 2B. The gas is very suitable because it uses a fluorine-based etching gas and reduces the film thickness of such a transparent conductive layer, or changes the resistance, brightness, and the like. Then, the PC VD device of the photosensitive resin pattern 84C is removed to cover the entire surface of the glass substrate 2, and the thickness of the film is as follows: for example, the film thickness of the substrate is as small as the second amorphous material containing phosphorus as an impurity. Device, cover film thickness 0. 1# m such as Ti, Ta and other heat-resistant metal film layer 34 as a heat-resistant metal cover film thickness.  The aluminum thin film layer 3 of 3 / m is used as the low resistance, and the source/drain wiring 2nd amorphous germanium layer 3 3 and the first amorphous germanium layer 3 1 B are formed by the two film thicknesses. And, by the technique, the photosensitive resin pattern 85 is sequentially etched to expose the layer 3 0 A, as shown in FIG. 3(e) and FIG. 4(e), selectively including a part of the pixel electrode 22 The drain electrode 2 1 of the laminated gate type transistor of 34A and 35A and the electrode terminal 5 A of the signal line 1 2 which serves as the source electrode and the signal line When the electrode terminal 6 A is etched during the etching of the gate-drain wiring 1 2, 2 1 and exposed to the glass substrate 2, the source/drain wiring 1 2 can be simplified to Ta, Cr, if the limitation of the resistance 不 is not critical. A single layer of Mo et al. In this manner, the active substrate 2 and the color filter panel obtained by bonding are laminated to complete the second embodiment of the present invention. In the first state, since the photosensitive resin pattern 85 is in contact with the liquid crystal, the photosensitive second SiNx is not generated or changed, and is used. 0 5 丨 layer 33, degree 譬 layer, and wiring layer. The material, and the micromachined gate are insulated to form the electrode of the wire formed by the package. Scan the beam source · up. Moreover, the shape of the light sheet of 2 1 and the liquid resin of the liquid 2 are -44 - 1300868 (42). The case 8 is not the use of a general photosensitive photosensitive material containing phenolic acid strontium resin as a main component, but the purity is used. In the main component, it is important to use a photosensitive organic insulating layer containing a polyacrylic acid resin or a poly n-imine resin with high heat resistance. Some materials may be fluidized by heating to cover the source depending on the material. The side of the NMOS wiring 1 2, 2 1 is formed. In this case, the reliability of the liquid crystal panel is further improved. As for the configuration of the storage capacitor 15 as shown in FIG. 3(e), the source/drain wirings 1 2, 2 1 and the storage electrode 7 3 including a part of the pixel electrode 2 2 are formed, and The structure of the protruding portion of the front scanning line 1 1 'the intermediate insulator's electric protective layer 7 1 A and the gate insulating layer 3 0 A, and the planar overlapping has been exemplified (the upper left to the lower right oblique portion 5 2 However, the structure of the storage capacitor 15 is not limited thereto. As in the first embodiment, the interposer includes the gate insulating layer between the scanning line and the simultaneously formed common capacitance line 16 and the pixel electrode 2 2 . 3 The insulation layer of 〇a can also be constructed. Further, other configurations are also possible, but detailed descriptions thereof will be omitted. In the second embodiment, the electrode terminal of the scanning line and the electrode terminal of the signal line have a limitation on the configuration of the device which is required to be a transparent conductive layer. However, it is also possible to remove the device and the process. The fourth embodiment will be described. (Third Embodiment) In the third embodiment, as shown in Fig. 5 (d) and Fig. 6 (d), the formation process of the contact formation process and the channel protective layer (etching stop layer) is approximated. Yu Di 2 is a process of the form of the form. However, it is not necessary to use the pseudo electrode terminal 94 as described below for the reason of -45-1300868 (43). Thereafter, the photosensitive resin pattern 84C is removed, and after the entire surface of the glass substrate 2 is covered with a film thickness of, for example, 〇·〇5 // m, the second amorphous germanium layer 3 3 containing impurities such as phosphorus is removed by using a PVCD device. Source. For the formation of the bungee wiring, a vacuum film forming apparatus such as S P T is used to sequentially cover the film thickness.  1 " m degree such as Ti' Ta _ heat resistant metal film layer 34 as a heat resistant metal layer, film thickness 0. The aluminum film layer 3 of 3 / m level is used as a low resistance wiring layer. Next, the source/drain wiring material composed of the two-layer thin film, and the second amorphous germanium layer 3 3 and the first amorphous germanium layer 3 1 B are used, and the photosensitive resin pattern 8 is used by the microfabrication technique. 6 sequentially etching to expose the gate insulating layer 30 A, as shown in FIG. 5(e) and FIG. 6(e), selectively forming a portion of the pixel-containing electrode 2 2 by 3 4 A and 3 The drain electrode 2 1 of the insulating gate type transistor formed by the stacking of 5 A and the signal line 12 which also serves as the source wiring are simultaneously formed when the source/drain wiring 1 2, 2 1 is formed. The electrode terminal 5 including the exposed scanning line electrode terminal forming region 5A and forming the scanning line and the electrode terminal 6 composed of one of the signal lines. That is, as in the second embodiment, the pseudo electrode terminal 94 is not necessarily required. At this time, the film thickness of 8 6 A on the signal line 1 2 is, for example, 3 m, which is thicker than the film thickness of the electrode on the electrode terminal 5, 6 and the electrode electrode 73 on the drain electrode 2 1 . The 5 # m thick photosensitive resin patterns 86A, 86B are formed in advance by a halftone exposure technique, which is an important feature of the third embodiment. The minimum size of 8 6 B corresponding to the electrode terminals 5, 6 is several ten # m, which is relatively large; although the mask manufacturing and manufacturing size management is extremely easy, it is the smallest corresponding to the signal line 2 field 8 6 A. The size is 1300868 (44) 4~8 // m 'The dimensional accuracy is high, so it is necessary to use a thinner gap as the halftone (ha 1 ft ο ne) field. However, as described in the previous example, the source of the present invention is compared to the source/drain wiring 1 2, 2 1 formed by one exposure treatment and two etching treatments. Since the drain wirings 1 2 and 2 1 can be formed by one exposure treatment and one etching treatment, there are few factors that affect the variation of the pattern width, and the size management of the source/drain wirings 1 2 and 2 1 is And the source/drain wiring 1 2, 2 1 , that is, the size management of the channel length is easier to manage the pattern precision than the previous halftone exposure technique. In addition, compared with the channel-etched insulating gate transistor, the conduction current of the insulating gate transistor is determined by the size of the channel protection insulating layer 3 2 A, instead of the source/drain wiring 1 2, 2 1 The size of the room is so easy to understand that it is easier to manage the process. After the source/drain wirings 1 2, 2 1 are formed, the photosensitive resin patterns 8 6 A, 8 6B are reduced in film thickness by an ashing means such as oxygen plasma. When the film is 5 m or more, the photosensitive resin pattern 8 6 B disappears, as shown in Fig. 5 (f) and Fig. 6 (f), the gate electrode 2 1 and the electrode terminals 5, 6 are exposed, and only the signal line When the photosensitive resin pattern 86C is selectively formed by the oxygen plasma treatment, the pattern width of the photosensitive resin pattern 86C is reduced, and the upper surface of the signal line 1 2 is exposed to reduce the reliability, so it is preferable to reduce the reliability. Enhance the anisotropy (the opposite sex) and suppress the change in the size of the pattern. Further, when the limitation of the resistance 値 is not critical, the structure of the source/drain wirings 1 2, 2 1 can be simplified to a single layer of Ta, Cr, Mo or the like. The active substrate 2 and the color filter obtained in this manner are bonded to each other to form a liquid crystal panel, and the third embodiment of the present invention is completed. Even in the third embodiment of the -47 - 1300868 (45) state, the photosensitive resin pattern 8 6 C is touched by the liquid crystal, so the photosensitive resin pattern 8 6 C does not use the ordinary component of the phenolic acid resin. Photosensitive resin, which is highly pure, and it is important to use a photosensitive organic insulating layer containing a polyacrylic resin or a polyimide resin with high heat resistance as the main component, and some may be heated by heating depending on the material. In addition, the surface of the source/drain wiring 1 2, 2 is covered, and in this case, the reliability of the liquid crystal panel is further improved. The configuration of the storage capacitor 15 is as shown in Fig. 5 (f), the source/drain wirings 1 2, 21, and the storage electrode 7 3 formed by including a part of the pixel electrode 2 2 , and The protrusion of the front scanning line 1 and the like, the intermediate plasma protective layer 7 1 A and the gate insulating layer 30 A, and the planar overlapping structure have been exemplified (the upper left to the lower right oblique portion 52). Further, the transparent conductive pattern 6 A (the pseudo electrode terminal 9 1 C ) formed under the electrode terminal forming region 5A and the signal line 12 and the transparent conductive layer pattern of the short-circuit line 40 are connected by making the shape into an elongated line The shape can be used as a high-resistance wiring for countermeasures against static electricity, but it is of course possible to use static electricity countermeasures using other conductive members. In the third embodiment of the present invention, the organic insulating layer is formed only on the signal line 12, and the drain electrode 2 1 is exposed while maintaining conductivity. Even in this case, sufficient reliability can be obtained. The driving signal of the liquid crystal cell is substantially an alternating current signal, and the direct current voltage is reduced between the counter electrode 14 and the pixel electrode 22 (the drain electrode 2 1 ), and the counter electrode is adjusted during the image inspection] 4 Since the voltage is lowered (the adjustment of the flash is reduced), the insulating layer may be formed in advance so that the DC component is only applied to the signal line 12. -48- 1300868 (46) In the second and third embodiments of the present invention, an organic insulating layer is formed only on the source/drain wiring and the signal line, respectively, and the manufacturing process is cut, but the organic insulating layer is Since the thickness is usually IM m or more, when the alignment film of the honing cloth is used for the alignment treatment, the height may cause a non-alignment state or may ensure the precision of the gap of the liquid crystal cell. Therefore, in the fourth embodiment, the passivation (p a s s i v a t i ο η ) technique is changed to the organic insulating layer by adding a minimum number of engineering numbers. (Fourth Embodiment) In the fourth embodiment, as shown in Fig. 7 (d) and Fig. 8 (d), the formation of the contact formation process and the channel protective layer (etching stop layer) is approximately the same as The process of the third embodiment is carried out. After the photosensitive resin pattern 84C is removed, a PVCD device is used on the entire surface of the glass substrate 2 to cover, for example, ruthenium. 〇5 / m m film thickness of the second amorphous layer 3 3 containing impurities, such as phosphorus, in the source and drain wiring formation project, using a vacuum film forming device such as SPT, sequentially covering the film thickness 0" / / The m-thickness such as Ti, Ta, and the like, the heat-resistant metal film layer 34 is used as an anodizable heat-resistant metal layer, and the film thickness is 0. The aluminum film layer 3 of 3 // m is used as the same anodizable low-resistance wiring layer. The source/drain wiring material composed of the two-layer thin film and the second amorphous germanium layer 3 3 and the first amorphous germanium layer are sequentially etched by the fine processing technique using the photosensitive resin pattern 87. 3 1 B, and the gate insulating layer 3 0 A is exposed, as shown in FIG. 7(e) and FIG. 8(e), selectively forming a part of the pixel-containing electrode 2 2 by 3 4 A and 3 5 The gate electrode 2 of the insulated gate type transistor formed by the layer A of A, and the signal line 1 2 which also serves as the source-49-1300868 (47) line; the source-drain wiring is formed at the same time. The scanning line electrode terminal which is exposed at the same time as 1 2, 2 1 forms the field 5 A, and also forms the electrode terminal 5 of the scanning line and the electrode terminal 6 composed of a part of the signal line. At this time, the film thickness (black area) of the 8 7 A on the electrode terminals 5, 6 is, for example, 3 μm, which corresponds to the field 8 b of the source/drain wiring 1 2, 2 1 and the storage electrode 7 3 . Film thickness (in the grayscale field) 1 .  The photosensitive resin pattern 8 7 A ′ 8 7 B which is thicker than v m is formed in advance by the half-color g-week (h a 1 f t ο n e ) exposure technique, and is an important feature of the fourth embodiment. After the source/drain wiring 1 2 ' 2 1 is formed, the photosensitive resin patterns 8 7 A, 8 7B are reduced in thickness by the oxygen electric ash ashing means. When 5 / m or more, the photosensitive resin pattern 8 7 B disappears, the source/drain wirings 1 2, 2 1 and the accumulation electrode 713 are exposed, and the photosensitive resin can be selectively formed only on the electrode terminals 5, 6 Pattern 8 7C. In the oxygen plasma treatment, even if the pattern width of the photosensitive resin pattern 87C is reduced, an anodized layer is formed only around the electrode terminals 5 and 6 having a large pattern size, and it has little effect on electrical characteristics, yield, and quality. A feature that is worth mentioning. The photosensitive resin pattern 8 7 C is used as a mask to illuminate, and as shown in FIGS. 7(f) and 8( f), the source/drain wirings 1 2, 2 1 are anodized to form an oxide layer 6 8 . 6 9, simultaneously anodizing exposed to the second amorphous germanium layer 3 3 A on the lower side of the source/drain wiring 1 2, 2 1 , and the first amorphous germanium layer 3 1 A to form an oxidation of the insulating layer矽 layer (S i 0 2 ) 6 6,6 7. After the anodization is completed, the photosensitive resin pattern 8 7 C is removed, and as shown in Fig. 7 (g) and Fig. 8 (g), the electrode terminal 5 composed of the low-resistance film layer on which the anodized layer is formed is exposed on the side surface thereof. ' 6. Scanning line power -50- 1300868 (48) The side of the pole 6 'flows through the snubber current 9' through the anti-static short-circuit line 9 1 C ', so it is understandable compared to the electrode terminal 5' of the signal line. The thickness of the insulating layer formed on the side is thin. Also, when the right resistance is not strict, the source. The structure of the drain wiring I 2, 2 1 can be simplified to be an anodizable T a single layer. The active substrate 2 and the color filter thus obtained are bonded to each other to form a liquid crystal panel. The table 4 of the present invention is completed. The structure of the storage capacitor 15 is 'as shown in FIG. 7( g )', and the source/drain wiring 1 2, 2 1 and the storage electrode 73 including a part of the pixel electrode 2 2 are provided, and The protrusion of the front scanning line 1 and the like, the intermediate plasma protective layer 7 1 A, and the gate insulating layer 30 A are planarly overlapped (the upper left to the lower right oblique portion 5 2 ). In the fourth embodiment, the source/drain wirings 1 2, 2 1 and the second amorphous germanium layer 3 3 A and the first amorphous germanium layer 3 1 A are anodized because of the gate electrode Since the pixel electrode 22 to which the electrical connection is 21 is also exposed, the pixel electrode 22 is also anodized at the same time, which is greatly different from that of the first embodiment. Therefore, the resistance 値 is increased by anodization as the film quality of the transparent conductive layer constituting the pixel electrode 22 is different. In this case, it is necessary to appropriately change the film formation conditions of the transparent conductive layer in advance. Membrane, but anodizing does not reduce the transparency of the transparent conductive layer. In addition, the current 'the anode of the anodized electrode 2 1 and the pixel electrode 2 2 is also supplied through the channel of the insulated gate type transistor, but since the area of the pixel electrode 22 is large, a large reaction current is required. Or a long-term reaction 'No matter how strong the external light is, the resistance of the channel portion will become an obstacle. On the drain electrode 2 1 and the accumulation electrode 73, it is formed on the signal line 1 2 -51 - 1300868 (49) The anodized layer of the same plasma film and film thickness is difficult to achieve only by the extension of the reaction time. However, even if the anodized layer formed on the drain wiring 2 1 is not sufficiently complete, it is likely to be practically unreliable and reliable. The reason is as follows: 'The driving signal applied to the liquid crystal cell is substantially alternating, and the image is formed between the counter electrode 14 and the pixel electrode 22 (the drain electrode 2 1 ) so that the DC voltage component is reduced. At the time of inspection, the voltage of the counter voltage 14 is adjusted (the adjustment of the flicker is lowered), that is, the insulating layer may be formed in advance so that the DC component flows only on the signal line 12. The liquid crystal display device described above is a TN type liquid crystal cell, but an IPS (In-Plain·S witching) which controls the lateral electric field by forming a pair of counter electrode and a pixel electrode at a predetermined distance from the pixel electrode. The liquid crystal display device of the present embodiment is also applicable to the engineering reduction proposed by the present invention, and will be described in the following embodiments. (Fifth Embodiment) In the fifth embodiment, first, a vacuum film forming apparatus such as SPT is used to cover a film thickness on one of the main surfaces of the glass substrate 2. 1~0. The first metal layer of 3#m degree, as shown in FIG. 9(a) and FIG. 10(a), selectively forms the scanning line 1 1 and the opposite electrode which serve as the gate electrode Π A by the micromachining technique] 6 〇 Next, on the entire surface of the glass substrate 2, using a PC VD device, for example, 0. 3 // m-0. 05 " 0. The film thickness of 1 / m is sequentially covered with the first S iNx (germanium nitride) layer 30 which becomes the gate insulating layer, and the first amorphous germanium which is almost free of impurities and becomes the insulating gate type transistor channel. (a - S i ) layer 3 1, 1300868 (50) and three kinds of thin film layers such as the second SiNx layer 32 which is an insulating layer of the protective channel are selectively formed by microfabrication technique as shown in FIG. 9(b) The second SiNx layer on the residual gate electrode 1 1 A is made thinner than the gate electrode 1 A to expose the first amorphous germanium layer 3 1 as 3 2 A. Next, as shown in FIG. 10(b), the second amorphous layer 33 containing impurities such as phosphorus is covered on the entire surface of the glass substrate by using a PVCD device, for example, at a film thickness of about 5 Å. As shown in Fig. 9 (c) and Fig. 10 (c), in the field outside the pixel display portion, in the field of electrode terminal formation of the scanning line U, an opening portion 63A is formed (which also serves as a storage capacitor). An opening portion 65 A ) is formed in the electrode terminal forming region of the opposite electrode of the line, and the second amorphous germanium layer 3 3 and the first amorphous germanium layer 3 and the gate in the opening portion 6 3 A are selectively removed. The insulating layer 30 is exposed to expose a portion 72 of the scanning line 11. Next, on the entire surface of the glass substrate 2, a vacuum film forming apparatus such as SPT is used, and the film thickness is sequentially covered by 0. For example, a heat-resistant metal thin film layer 34 such as Ti or Ta is used as the heat-resistant metal layer, and an aluminum thin film layer 35 having a thickness of about 0·3 // m is used as the low-resistance wiring layer. Then, the source/drain wiring material composed of the two-layer thin film and the second amorphous layer 3 and the first amorphous layer are sequentially etched by the fine resin technique using the photosensitive resin patterns 86A and 86B. The layer 3 1 is exposed to expose the gate insulating layer 30, as shown in FIG. 9(d) and FIG. 1(d), on the gate insulating layer 30, selectively formed by the stacking of 34A and 35A. The gate electrode 2 1 of the gate insulating type transistor which is a pixel electrode and the signal line I 2 which also serves as the source wiring form the source/drain wiring 2, 2], and include the opening portion 63. The electrode terminal 6 formed by the electrode terminal 5 of the scanning line and one of the signal lines 12 is also formed at the same time as the inner portion 1300868 (51). At this time, in the same manner as in the third embodiment, the film thickness of 8 6 A on the signal line 1 is, for example, 3 " m, and is formed on the gate electrode 21 and the electrode terminal 5 by a halftone exposure technique. 6 on the 86B film thickness 1. 5/im is also thicker than the photosensitive resin pattern 8 6 A, 8 6 B. After the source/drain wirings 1 2 and 2 1 are formed, the photosensitive resin patterns 84A and 84B are reduced in thickness by 1·5 // m or more by the ashing means such as oxygen plasma, and the photosensitive resin pattern 86B is used. Disappearing, as shown in Fig. 9(e) and Fig. 1(e), while the drain wiring 2 1 and the electrode terminals 5, 6 are exposed, the photosensitive resin pattern 8 6C is selectively formed only on the signal line 1 2 . In the oxygen plasma treatment, it is preferable to suppress the change in the size by suppressing the anisotropy (the anisotropy) so that the pattern of the photosensitive resin pattern 86 6C is not narrowed. Further, when the limitation of the resistance 値 is not critical, the structure of the source/drain wirings 12 and 21 can be simplified into a single layer of Ta, Cr, Mo or the like. In this manner, the obtained active substrate 2 and color filter are bonded to each other to form a liquid crystal panel, and the fifth embodiment of the present invention is completed. In the photosensitive resin pattern 8 6C, an ordinary photosensitive resin containing a phenolic strontium resin as a main component is not used, but high purity is required, and the heat resistance of the main component using a polyacrylic resin or a polyimide resin is high. The necessity of the photosensitive organic insulating layer has been previously described. As for the structure of the storage capacitor 15 as shown in FIG. 9(e), the counter electrode (accumulation capacitance line) 16 and the pixel electrode (drain electrode) 2 1 intermediate gate insulating layer 30 are exemplified. Planar weight -54- 1300868 (52) The field of the stack 5 0 (the upper left to the lower right oblique line) constitutes an example of the storage capacitor 15 as for the gate electrode 2 1 and the front scanning line 1 1 the intermediate gate insulating layer It is also possible to constitute the storage capacitor 15 by 30, but the detailed description thereof is omitted here. Further, in Fig. 9(e), the electrode terminal 5 of the scanning line and the electrode terminal 6 of the signal line are connected by a high-resistance member, and in the case of an IP S-type liquid crystal display device, since a transparent conductive layer is not required, it is used. An electrostatic countermeasure or design technique in which any one of a scanning line material, a signal line material, or a semiconductor layer is connected by an insulated gate type transistor or an elongated conductive line in an OFF state, although not specifically illustrated, The opening portion 63 3 A is provided to expose a portion of the scanning line 1 1 to the portion 7 2 , so that the countermeasure against static electricity is easily achieved. According to the fifth embodiment of the present invention, the organic insulating layer is selectively formed only on the signal line to promote the reduction of the manufacturing process, but the thickness of the organic insulating layer is 1 // m or more, thereby ensuring the gap precision of the liquid crystal cell. There will be obstacles. Therefore, in the sixth embodiment, a passivation technique in place of the organic insulating layer is provided by adding a minimum number of processes. (Sixth Embodiment) In the sixth embodiment, as shown in Fig. 1 1 (c) and Fig. 1 2 (c), the opening portion 63 A is formed until the scanning line 1 is formed in the electrode terminal forming region of the scanning line]1. One of the portions 7 and 2 is almost the same as the fifth embodiment. Next, in the source/drain wiring formation process, the SPT Temple vacuum film is used to directly cover the film thickness (7), such as T i, T a and other heat-resistant metal film layer 34 as an anodizable heat-resistant gold. -55- 1300868 (53) genus layer, film thickness 0. The aluminum film layer 3 of 3 / m is used as the same low-resistance wiring layer which can be oxidized by the anode. Then, the source/drain wiring material composed of the two-layer thin film and the second amorphous sand layer 3 3 and the second amorphous sand layer 3 1 are formed by the fine processing technique using the photosensitive resin pattern 87. The exposed insulating layer 30 is exposed, as shown in FIG. 11 (d) and FIG. 2 (d), and a layer of 34A and 35A is selectively formed on the gate insulating layer 30 to form an insulating layer of the pixel electrode. The gate electrode 21 of the gate type transistor and the signal line 12 which also serves as the source wiring. When the source/drain wirings 1 2, 2 1 are formed, the electrode terminals 5 including the scanning lines of a portion 7 2 of the scanning lines 1 1 exposed in the openings 63 A are formed simultaneously and by the signal lines. A part of the electrode terminal 6 is formed. At this time, the film thickness (black area) of the 8 7 A on the electrode terminals 5, 6 is, for example, 3 // m, which corresponds to the field 8 7B (intermediate adjustment field) corresponding to the source/drain wiring 12, 2 1 . Film thickness 1 .  The light-sensitive resin pattern 87 A, 87B, which is 5 / m thick, is formed in advance by a halftone exposure technique, which is an important feature of the sixth embodiment. After the source/drain wirings 1 2, 2 1 are formed, the photosensitive resin patterns 87 A and 87B are reduced in film thickness by an ashing means such as oxygen plasma. When 5 / m or more, the photosensitive resin pattern 87B disappears, and the source/drain wirings 1 2, 2 1 are exposed, and the photosensitive resin patterns 87 A, 87B can be selectively formed only on the electrode terminals 5, 6. Then, the photosensitive resin pattern 8 3 is used as a mask to irradiate light, and the oxide layer 6 is formed by anodizing the source/drain wirings 1 2, 2 ] as shown in Fig. 1 1 (e) and Fig. 1 2 (e). 8,6 9, at the same time, the anodic oxidation is exposed to the second amorphous germanium layer 3 3 A and the third amorphous germanium layer 3 1 A on the lower side of the source/drain wiring] 2, 2 1 to form an insulating layer. -56- 1300868 (54) Cerium oxide layer (Si〇2) 66,67. After the completion of the anodization, when the photosensitive resin pattern 8 7 C is removed, as shown in Fig. 1 1 (f) and Fig. 12 (f), the electrode terminal 5'6 composed of the low-resistance film layer is exposed. Further, the structure of the S-header source/drain wiring 1 2 ' 2 1 which is not restricted by the resistance 亦可 can be simplified into an anodizable single layer. In this manner, the obtained active substrate 2 and color filter are bonded to each other to form a liquid crystal panel, and the sixth embodiment of the present invention is completed. Regarding the structure of the storage capacitor 15 as shown in FIG. 11 (f), the counter electrode (accumulation capacitance line) 16 and the pixel electrode (drain electrode) 2 1 intermediate gate insulating layer 3 0 are exemplified. The overlapping area 50 (the upper left to the lower right oblique line portion) constitutes an example of the storage capacitor 15. Further, in Fig. 11 (f) and Fig. 12 (f), the countermeasure against static electricity which is connected by the high-resistance member between the electrode terminal 5 of the scanning line and the electrode terminal 6 of the signal line is not particularly shown, so the signal The electrode terminal 6 of the wire 12 is different from the source/drain wiring 1 2, 2 1 in that an anodized layer of an insulating layer is formed only on the side surface, and anodization is not formed on the side surface of the electrode terminal 5 of the scanning line 1 1 . The layer is provided with the opening portion 63 A to expose a portion 7 2 of the scanning line 11 as described above, so that it is easy to carry out the countermeasure against static electricity, and the electrode at the scanning line 1 1 is used for the countermeasure against static electricity. The side of the terminal 5 also forms a thin anodized layer, and it goes without saying. In the fifth and sixth embodiments, when the drain wiring is formed, a novel passivation method is applied by applying a halftone exposure technique, and engineering reduction is also performed, and the liquid crystal display device is realized by four masks. In the same manner as in the first to fourth embodiments, the halftone (halftone) exposure technique is formed by forming an opening portion of the engineering and gate insulating layer at -57-1300868 (55) of the etch-off layer. The liquid crystal display device for producing a reticle is described in the seventh and eighth embodiments because it is expected to further reduce the manufacturing process. (Seventh Embodiment) In the seventh embodiment, first, a vacuum film forming apparatus such as SPT is used to cover the film thickness on one main surface of the glass substrate 2. 1 ~ 〇. The metal layer of the 3/m level, as shown in Fig. 13 (a) and Fig. 14 (a), selectively forms the scanning line 1 1 and the pair which serve as the gate electrode 1 1 A by the micromachining technique. Next to the electrode 16 6 , on the entire surface of the glass substrate 2, a PC VD (plasma chemical vapor deposition) device is used to sequentially cover 〇·3 vm - 0 · 0 5 // m - 0 · 1 μm. a first S iN X (tantalum nitride) layer 30 that becomes a gate insulating layer, and a first amorphous germanium (a-Si) layer 31 that is substantially free of impurities and serves as a channel for the insulating gate type transistor. And three types of thin film layers, such as the second SiNx layer 3 2 which is an insulating layer of the protective channel, have an opening portion 6 3 A in the field of electrode terminal formation of the scanning line ij in the field outside the image display portion, and at the same time as the protective insulating layer In the field of formation, that is, the film thickness of the field 82A on the gate electrode A is 2 # m, and a photosensitive resin pattern thicker than the film thickness 1 β m of the other field 82B is formed by a halftone exposure technique. 82A, 82B, with the photosensitive resin pattern 8 2 A, 8 2 B as a mask, as shown in FIG. 3 (b) and FIG. 14 (b), selectively removing the opening 63A 2 SiNx layer 32, and 3], a first amorphous silicon layer and the gate insulating layer 3 billion electrode, is exposed scan -58- (56) 1300868 1 1 one part of the line 72. When the photosensitive resin pattern 8 2 A, 8 2 B is reduced by a thickness of 1 // m or more by the ashing means such as oxygen plasma, the photosensitive resin pattern 82B disappears, as shown in FIG. 13(c) and FIG. As shown in FIG. 4(c), the second SiNx layer 3 2B is exposed, and the photosensitive resin pattern 82C can be selectively formed only in the field of protective insulating layer formation. In the above oxygen plasma treatment, it is preferable to enhance the anisotropy (tropicality) in order to suppress the change in the pattern size, which has been described previously. Next, as shown in FIG. 13 (c) and FIG. 14 (c), the photosensitive resin pattern 8 2C is used as a mask, and the second SiNx layer 32 is selectively etched to be wider than the gate electrode 1 1 A. The second SiNx layer 32 is fine, and the first amorphous layer 31 is also exposed. At this time, a part of the exposed portion of the scanning line 1 1 is exposed to the etching gas or the etching of the second SiNx layer 32. Therefore, it is necessary to note that the scanning line 11 is included as the material of the scanning line 1 1 is different. The film thickness of a portion 72 is reduced, but the countermeasures are as described previously. Then, the photosensitive resin pattern 82C is removed, and the second amorphous germanium layer 3 containing impurities such as germanium is covered on the entire surface of the glass substrate 2 by a PCVD apparatus, for example, at a thickness of about 0.05 μm. A vacuum film forming apparatus such as SPT is used to sequentially cover a film thickness of m m such as Ti 'Cr, Mo, or the like, as a heat resistant metal film, and a film thickness 〇.  The aluminum film layer 3 of 3 / m is used as a low-resistance wiring layer. Next, the source/drain wiring material and the second amorphous germanium layer 3 and the first layer formed by the two-layer thin film are sequentially etched by the micro-machining technique using the photosensitive resin patterns 8 6 A, 8 6 B An amorphous germanium layer 3 1 is exposed to expose the gate insulating layer 30, and on the gate insulating layer 30, a layer of 34 A and -59-1300868 (57) 3 5 A is selectively formed into a pixel. The gate electrode 2 of the gate of the electrode and the signal line 12 which also serves as the source wiring also include the exposed opening portion 6 when the source/drain wiring 1 2, 2 1 is formed. An electrode terminal 6 composed of a portion of the electrode terminal 5 and the signal line 12 of the scanning line is formed by the second amorphous germanium layer 3 3 C in the vicinity of A. At this time, similarly to the third embodiment, the film thickness of 86 A on the signal line 12 is, for example, 3 // m, and the ratio is formed by the halftone (ha 1 ft ο s ) exposure technique and the gate electrode 2 1 . The film thickness of 86B on the electrode terminals 5, 6 is 1. 5 # m is also thick photosensitive resin pattern 86A, 86B. After the source/drain wirings 1 2, 2 1 are formed, the photosensitive resin patterns 86 A and 86B are reduced in film thickness by an ashing means such as oxygen plasma. When 5 / m or more, the photosensitive resin pattern 86B disappears, and as shown in FIG. 13 (f) and FIG. 4 (f), the gate electrode 21 and the electrode terminals 5, 6 are exposed, and only the signal line 1 can be used. The photosensitive resin pattern 8 6 C is selectively formed on 2. In the oxygen plasma treatment, it is preferable to enhance the anisotropy (tropicality) and to suppress the change in the pattern size so that the pattern of the photosensitive resin pattern 8 6 C is not narrowed. If the limitation of the resistance 値 of the source/drain wirings 12 and 2 is not critical, it can be simplified into a single layer. The obtained active substrate 2 and color filter are bonded to each other to form a liquid crystal panel, and the seventh embodiment of the present invention is completed. In the photosensitive resin pattern 8 6C, an ordinary photosensitive resin containing a bismuth phenolate resin as a main component is not used, but a high-sensitivity photosensitive material having a high purity and a high viscosity of a main component containing a polyacrylic resin or a polyimide resin must be used. The necessity of an organic insulating layer has been described previously in -60-1300868 (58). Regarding the structure of the storage capacitor 1 5, as shown in Fig. 13 (f), the counter electrode (accumulation capacitance line) 16 and the pixel electrode (drain electrode) 2 1 intermediate gate insulating layer 3 0 are illustrated. On the other hand, the planar overlapping field 10 field (the upper left to the lower right oblique line portion) constitutes an example of the storage capacitor 〖5, and the pole wiring 2 1 and the preceding scanning line 1 1 are the intermediate gate insulating layer 3 〇 to constitute the storage capacitor. It is also possible to use 1 5, and detailed description thereof is omitted here. Further, in Fig. 13 (f), between the electrode terminal 5 of the scanning line and the electrode terminal 6 of the signal line, a high-resistance member such as an insulated transistor or an elongated conductivity in an OFF state is used. The static electricity countermeasures for the connection of the line are not shown in the figure. However, since the opening portion 6 3 A is provided and the part of the scanning line y j is exposed, the static electricity countermeasure is easy to adopt. According to the seventh embodiment of the present invention, the organic insulating layer is formed on the signal line to reduce the manufacturing process. However, since the thickness of the organic insulating layer is j // m or more, the gap precision of the liquid crystal cell may be ensured. There are obstacles. Therefore, in the eighth embodiment, a passivation technique in place of the organic insulating layer is provided by adding a minimum number of engineering numbers. (Eighth Embodiment) In the eighth embodiment, as shown in Fig. 15 (d) and Fig. 16 (d), the opening portion 6 3 A is formed until the electrode terminal forming region of the scanning line 1 1 is exposed. A portion of the scanning line 1 1 and a portion of the etched layer 3 2 A are formed in the same manner as in the seventh embodiment. Next, the above-mentioned photosensitive resin pattern 8 2 C is removed in order to fully use the glass substrate. 1300868 (59) PC VD device covers, for example, 0. The second amorphous layer 33 containing a film thickness of 5 μm, such as phosphorus, is covered with a vacuum film forming apparatus such as SPT. 〗 〖Vm degree such as Ti, Ta and other heat-resistant metal film layer 34 as an anodizable heat-resistant metal layer, followed by a film thickness of // 3 / m of aluminum film layer 35 as the same anodizable low-resistance wiring Floor. Next, the source/drain wiring material composed of the two-layer thin film and the second amorphous germanium layer 3 3 are sequentially sequentially etched using the photosensitive resin patterns 8 7 A, 8 7 B by a microfabrication technique. The first amorphous germanium layer 3 1, exposes the gate insulating layer 30, as shown in FIG. 15(e) and FIG. 16(e), on the gate insulating layer 30, selectively formed by 34A and 35 The gate electrode 2 of the insulating gate type transistor which becomes the pixel electrode and the signal line 12 which also serves as the source wiring is formed in the source and drain wiring 1 2, 2 At 1 o'clock, the second amorphous germanium layer 3 3 C in the vicinity of the opening portion 6 3 A is simultaneously formed to form the electrode terminal 5 of the scanning line and the electrode terminal 6 composed of a part of the signal line. At this time, the film thickness (black field) of the 8 7 A on the electrode terminals 5, 6 is, for example, 3 // m, and the ratio of the formation is previously formed by the halftone exposure technique to correspond to the source/drain wiring 1 2, 2 1 field 8 7 B (gray scale area) film thickness 1 · 5 // m Thick photosensitive resin patterns 8 7 A, 8 7 B are important features of the eighth embodiment. After the source/drain wirings 1 2, 2 1 are formed, the photosensitive resin patterns 87A, 87B are reduced in film thickness by an ashing means such as oxygen plasma. When 5 /i m or more, the photosensitive resin pattern 8 7 B disappears, and the source/drain wirings 1 2, 2 1 are exposed, and the photosensitive resin pattern 87C can be selectively formed only on the electrode terminals 5, 6. Here, the photosensitive resin pattern 87C is used as a cover 1300868 (60) to illuminate the light, and as shown in Fig. 15 (f) and Fig. 16 (f), the anode is oxidized. The drain wiring 1 2, 2 1 forms an oxide layer 6 8 ' 6 9 ·' while anodizing is exposed to the second amorphous germanium layer 3 3 A on the lower side of the source/drain wiring 1 2, 2 1 , and The first amorphous germanium layer 3 1 A forms a tantalum oxide layer (SiO 2 ) 66, 67 of an insulating layer.

When the limitation of the resistance 并不 is not critical, the structure of the source/thin wiring 1 2, 2 ] can be simplified to an anodizable Ta single layer, as shown in Fig. 15 (g) and Fig. 16 (g). The countermeasure against static electricity connected between the electrode terminal 5 of the scanning line and the electrode terminal 6 of the signal line by a high-resistance member is not particularly shown, and the electrode terminal 6 of the signal line 2 is only connected to the source/drain wiring 1 2, 2 1 different side, the anodized layer of the insulating layer is changed, but it is not necessary to explain that the electrode terminals of the static electricity are connected by appropriate conductive members, and a plurality of anodes are also formed on the side of the electrode terminal 6 of the scanning line. Oxide layer. In this manner, the obtained active substrate 2 and the color filter are bonded to each other to form a liquid crystal panel, and the eighth embodiment of the present invention is completed. As shown in FIG. 15 (g), the structure of the storage capacitor 15 is displayed, and the counter electrode (accumulation capacitance line) 16 is overlapped with the pixel electrode (drain electrode) 2 1 intermediate gate insulating layer 30. The field (the lower right oblique line portion) constitutes an example of the storage capacitor 15 . [Effect of the Invention] As described above, in the liquid crystal display device of the present invention, the insulating gate-63-1300868 (61) pole type transistor has a protective insulating layer on the channel, so that it is only in the source of the image display portion. Selectively forming a photosensitive organic insulating layer on the wiring, or only on the signal line, or anodizing the source/drain wiring formed of the anodizable source and the drain wiring to form an insulating layer. Passivation function. Therefore, the insulating gate type transistor which does not have a special heating process and which has an amorphous germanium layer as a semiconductor layer does not require excessive heat resistance. In other words, there is also an effect of passivation formation without deterioration of electrical properties. Further, when the source/drain wiring is anodized, the electrode terminal of the scanning line or the signal line can be selectively protected by introducing a halftone exposure technique, which can prevent an increase in the number of photo etching processes. In addition, by introducing a halftone exposure technique, a mask can be used to process the formation of the etch-off layer, and the engineering of the opening formation of the gate insulating layer is reduced by the pseudo-pixel electrode. The introduction of 'processing of the pixel electrode and the scanning line with a mask can rationalize the number of photographic etching processes from the previous five times, and the liquid crystal display device can be fabricated using four or three masks. This is the result of reducing the number of manufacturing processes for the active substrate. From the point of view of overall cost reduction, it is the biggest feature that has been specifically mentioned. Moreover, the pattern precision requirements of these projects are not very high, so they have little effect on yield or quality, and are also easy to produce and manage. Further, in the IP S-type liquid crystal display device produced in the fifth and seventh embodiments, the electric field generated between the counter electrode and the pixel electrode is applied only to the gate insulating layer, and the sixth and the sixth According to the eighth embodiment of the present invention, the PS-type liquid crystal display device is applied to the gate insulating layer and the anodized layer of the pixel electrode, so that the conventional defect of the intermediary is not so severe -64-1300868 (62) The advantage of purifying the insulating layer and having a phenomenon of scorching after the display image is not negligible. Since the anodization G of the drain wiring (pixel electrode) is inferior to the δ-bar insulating layer as it functions as a high-resistance layer, no charge accumulation is generated. In addition, the requirements of the present invention, as can be seen from the above description, are in the case of an insulated gate type transistor which is cut-off type, using anodizable source and drain wiring, and anodizing source and drain In addition to the other configuration, the semiconductor device for a display device such as a material or a film thickness of a different pixel electrode, a gate insulating layer, or the like, or a manufacturing method thereof, also belongs to the present invention. It is apparent in the field that the practicality of the present invention is constant even for a reflective liquid crystal display device, and the semiconductor layer of the insulated gate type transistor is not limited to an amorphous germanium.
