Description
1353968 (1) 九、發明說明 【發明所屬之技術領域】 本發明是關於使用於液晶面板的製造等之曝光用 基板。 【先前.技術】 —般,TFT液晶面板,是採用:在組裝有TFT 的陣列側基板與裝設有濾色器之基板間封裝液晶,以 控制電壓來控制液晶的定向之現用方法。 在陣列側製造之際,藉由光曝光來將被描繪有被 大型光罩的電路之裸板複數層燒附於無鹼之母玻璃板 法。一方面,濾色器側也同樣地’以被稱爲染料含浸 使用微影的方法來製造。 在陣列側、濾色器側之任何一方的製造,均需要 光罩,爲了實施精度良好之曝光,作爲這些大型光罩 料,主要使用線膨脹係數小之合成石英基板。 一方面,在使用倒角機來將基板的外周面倒角成 之形狀的情況時,作爲可左右製品的表面狀態特別是 面有無受到污染之原因之一,可舉出來自於外周面部 塵埃之影響。在基板的外周面部分之粗糙度爲粗的情 ,以洗淨無法完全將附著於外周面之污垢洗淨,污垢 由該處附著於基板表面,且爲了除去該污垢而必須進 洗淨或再硏磨,會引起成品良率之惡化。 爲了解決如此之問題,在I c光罩用基板的情況 大型 元件 TFT 稱爲 的方 法之 大型 之材 任意 在表 分的 況時 不僅 行再 ,.採 -4- (4) (4)1353968 塵埃(粒子)多,基板表面的污垢變得嚴重。 在欲獲得如此曝光用大型基板的情況,首先進行曝光 用大型基板的外周面之倒角加工。倒角加工通常是以鑽石 硏磨來進行,期望鑽石粒徑爲#600〜#】500。 在呈任意形狀地進行倒角加工後,經過硏磨工序,爲 了使基.板外周面的粗糙度提昇而進行外周面加工。外周面 加工是藉由使用外周面準鏡面加工裝置,將任意大小的基 板之外周全部進行例如刷硏磨來進行。即,一邊使耐綸製 的刷旋轉,一邊使基板外周部分任意地橫行來加工。然後 ,對於主面表面實施最終拋光加工。再者,基板外周面加 工是亦可不在硏磨工序後來進行。 此時,考量下述點爲佳。即,在外周面準鏡面化的次 工序,洗淨基板之際,在基板濕潤的狀態下以人的手僅夾 持基板的外周面來進行操作。在已經濕潤的狀態,外周面 形成容易滑動之狀態。在手戴上專用的手套(搬運用手套 )。在以戴有手套之手,僅握持乾燥或濕潤之基板的外周 面進行操作之際,受到基板外周面的粗糙度,特別是接近 鏡面時,則握持基板的手滑動,而無法進行搬運操作。 若明白基板外周面的粗糙度與以戴有手套之手的搬運 之關係的話,則能以外周面準鏡面加工裝置來控制基板外 周面的粗糙度,作出可搬運之外周面狀態。在該外周面狀 態下,亦可爲可抑制來自於基板外周面的塵埃之等級。 因此,爲了明白作成能夠僅以戴有手套的手握持呈濕 潤狀態的基板之外周面的外周面之面粗糙度基準,而調查 1353968
基板質量、與戴有手套的濕潤狀態下變得無法保持基板外 周面之基板外周面的面粗糙度的關係(參照第1圖)。具 體而言,在夾持基板的彈簧、與質量及外周面粗糙度Ra 爲已知的任意之基板的外周面之間經由水裝設搬運用手套 ,在兩端的彈簧施加一定的力量後,夾入基板。然後,在 該狀態下將基板舉起,使用彈簧式張力計來測定當基板剛 開始滑動時之拉起力,取與上述夾入基板的力之比來作爲 靜摩擦係數。 再者,在第1途中之人的夾入力是4.5〜5.0 kg。 面粗糙度(Ra )是觸針式表面粗糙度計來測定。根據 其結果,可得知根據基板的質量,大致一定地決定可搬運 的基板外周面粗糙度。整理該關係可得知,基板的靜摩擦 係數是形成:基板質量/ 2x(0_02〜0.03)。再者,由圖 ,若得知任意基板之質量的話,則亦可推測可搬運之基板 外周面的面粗糙度之値。
即使在基板爲乾燥或濕潤的狀態下,以上述表面粗糙 度以上,能夠進行搬運。針對在濕潤狀態下的基板外周面 的握持,確認了 :靜摩擦係數的値是比起般運用手套的種 類,更受到基板外周面的粗糙度所影響。 若進行外周面加工,將基板外周面控制於上述表面粗 糙度的話,則能進行任意的基板之搬運,且能夠抑制來自 於外周面之麈埃。 又,針對在洗淨中由基板外周面所產生的粒子,在耐 熱玻璃(登錄商標:Pyrex )檀,將大小520 x 8 00、厚度 -8- (6) 1353968 10 mm之基板與基板座一同浸漬,照射l〇分鐘 、2 00W之超音波,以粒子計數器測定所產生之卷 其結果如第2圖所示。縱軸爲顯示:將基板 糙度爲0.6 時的粒子產生數作爲100時之相 產生的粒子數是外周面的粗糙度越粗則越多,隨 而減低,在Ra爲0.3 e m以下大致可抑制粒子產 者,來自於基板座之產生粒子數是被減去的。 〔實施例〕 以下,顯示實施例及比較例,具體地說明本 本發明是不限於下述實施例者。 [實施例]] 使用# 1 200的鑽石粒,以倒角裝置將大小 mm、厚度10.0 mm、質量9.2kg之合成石英基板 加工,準備原料基板。其次,進行硏磨加工、一 工,以及外周面加工。然後,使用觸針式粗糙度 周面的粗糙度,得知Ra=0_05//m。 將基板的主面表面進行最終硏磨,在洗淨工 有手套的手進行搬運操作之結果,能夠達到以手 測靜摩擦係數爲〇_ 12)。再者,手套的材質是使 烯製、聚乙烯製者。基板是即使在乾燥或濕潤之 同樣地可進行板運。洗淨後的基板之淸淨度良好 沒有產生粒子。. 之 36kHz :子。 外周面粗 對値。所 著變光滑 生量。再 發明,但 520x800 進行倒角 次抛光加 計測量外 序,以戴 握持(推 用聚氯乙 狀態下, ,且幾乎 (7) (7)1353968 [實施例2] 使用#800的鑽石粒,以倒角裝置將大小700x800 mm、厚度8.0 mm、質量9.9kg之合成石英基板進行倒角 加工,準備原料基板。然後,進行與實施例1相同之加工 的結果’Ra = 0.09。將所獲得的基板進行與實施例1同樣 之搬運操作,獲得相同之結果(推測靜摩擦係數爲0.1 3 ) [實施例3] 使用#12〇0的鑽石粒,以倒角裝置將大小800x920 mm、厚度10.0 mm、質量13.0kg之合成石英基板進行倒 角加工,準備原料基板。然後,進行與實施例1相同之加 工的結果,Ra=0.16。將所獲得的基板進行與實施例1同 樣之搬運操作,獲得相同之結果(推測靜摩擦係數爲0.1 6 [比較例](不實施外周面加工之情況) 使用#800的鑽石粒,以倒角裝置將大小700x800 mm、厚度8.0 mm'質量9.9kg之合成石英基板進行倒角 加工,準備原料基板。其次,進行硏磨加工、一次拋光加 工後,不進行外周面加工,而使用觸針式粗糙度計測量外 周面的粗糙度,得知Ra=0.5//m。 . 然後,將基板的主面表面進行最終硏磨.,在洗淨.工序 -10- (8) (8)1353968 ,以戴有手套的手進行搬運操作之結果,能夠達到以手握 持(推測靜摩擦係數爲0.24)。手套的材質是使用聚氯乙 烯製者。基板是即使在乾燥或濕潤之狀態下,同樣地可進 行板運,但洗淨後的基板之淸淨度差,且產生多數之粒子 〔發明效果〕 若根據本發明的曝光用大型基板的話,則由於可大幅 地減低:在洗淨時由基板外周部面釋出之粒子,故能夠提 昇大型基板之洗淨成品良率。又,由於可進行基板之搬運 ,故能夠不需導入搬運設備而提昇基板品質。 【圖式簡單說明】 第1圖是顯示各種夾持力之外周面粗糙度與靜摩擦係 數之關係的圖表。 第2圖是顯示外周面粗糙度與粒子數之關係的圖表。 -11 -
