圖3顯示根據本發明之第二項具體實施例的焊墊結構。 此第二項具體實施例的主要特徵在於,使圖2中所示之第 一項具體實施例的錐狀接點孔及栓2 9 〇之深度達到最小化 。為產生此種深度最小化,將圖2中的虛設圖樣⑷提高到 該電容208頂部表面的高度。如圖3中所示,包括元件 、23 0與250的一升高之虛設圖樣允許使用較短的栓。 此種較短的栓295更能防止各種因素導致的不連續,此類 因素包括因深度蝕刻孔而自然產生之錐狀,以及(尤其在 高密度1C中)該接點孔狹窄底部可能存在的雜質及/或^完 整金屬沈積。 圖4-1到4-18為一焊墊結構的斷面圖,顯示於形成一記 憶體開關電晶體12〇之後,用以同時在焊墊區A2,或A2,,中 製k焊墊並在一記憶體單元區A1中製造一單元電容2〇8 的方法之步驟。在圖‘丨到仁:^中,為提供並顯示本發明 之替代性具體實施例,故將焊墊區A2,與A2”顯示於同一 圖中,而不致使本發明的範疇限制於圖中。因此,應明瞭 烊墊區A2代表本發明的一項具體實施例,而焊墊區A2,, 則代表本發明的另一項具體實施例。然而,亦應明瞭圖4_ 1到4-1 8中所示的具體實施例並不能限制本發明的範疇, 因其僅係本發明之較佳具體實施例,而並非限制本發明之 申請專利範圍的範鳴。 請參考圖4-1到圖4-7,有一淺溝渠隔離(STi)區合宜地形 成於一半導體基板1〇〇上,且由裝置隔離區u〇所包圍,在 該隔離區110之間配置有一作用區,其中並形成電晶體12〇 -14- 本紙張尺度適用中國國家標準(CNS) A4規格(210X 297公釐) 574740 A7 _— B7 五、發明説明(n ) °接著’有一第一層間介電質130沈積於該半導體基板100 及電晶體120的整個表面上,其係接著最好由一化學機械 研磨(CMP)程序整平,產生一均勻表面以供後續沈積層使 用。 接著’形成一接點焊墊135,並有一第二層間介電質14〇 沈積於該半導體之整個表面上。然後,於該第二層間介電 質140上執行一蝕刻程序,以同時形成一範例性接點孔(直 接接觸孔)150用以電氣連接電晶體12〇之一源極/汲極區與 單疋區A1中的一位元線,並形成一溝渠155,如圖4-3中所 示。溝渠1 5 5的大小最好係與一後續覆蓋其上之焊塾(如圖 1-3之焊墊350)—般。 如圖4-4中所示,接著將直接接觸孔150以諸如鎢等的導 電材料填滿,最好係利用一化學汽相沈積法(CVD)所沈積 。該導電材料最好係沈積覆蓋整個第二層間介電質丨4〇, 然後利用一回蝕程序將其自溝渠1 5 5上移除。接著形成諸 如位元線160之類的導電線路,然後即如圖4巧中所示,有 一第三層間介電質170沈積於該組件上。 在下一項代表性步驟中,如圖4-6中所示,在該第三層 間介電質170中形成一接點孔(埋入式接點孔)18〇,以在電 容之一下部電極210與該電晶體120之一源極/汲極區之間 提供如圖1至3中所示之一範例性連結。接著,將埋入式接 點孔180以諸如經摻雜之多晶矽之類的導電材料填滿。接 著,如圖4-7中所示,將一蝕刻停止層i 85沈積於該組件之 整個表面上。如圖4-7之右側部分所示,即使在形成第= -15- 本紙張尺度適用中國國家標準(CNS) A4規格(210 X 297公釐) 574740
層間介電質170與蝕刻停止層185之後,該組件表面上仍會
留下一凹陷處,其高低段差與圖4-3中之溝渠155的深度相 當。 X 該蝕刻停止層185可能係由氮化矽(shN4)所構成,而該 第一、二及三層間介電層130、14〇與17〇則可能係分別由 /一氧化矽材料所構成。溝渠155的大小(其橫向尺寸或直 徨)係取決於該焊墊350之大小。例如··溝渠155的表面積 最好是不大於100微米(μπι)χ1 00微米,相等於代表性的焊 塾350的面積’且其溝渠深度則為〇.2至〇5微米。該第一、 二及三層間介電層130、140與170分別可形成〇·3至1〇微米 之厚度。該蝕刻停止層185之厚度可為50至500埃(Α)。 請參考圖4-8,為在蝕刻停止層185上形成一圓柱形電容 器之下部電極,最好在該組件整個表面上形成一模製氧化 物層190。模製氧化物層190最好係由一氧化矽層利用化學 汽相沈積(CVD)程序所製成,該模製氧化物層ι9〇之厚度 係取決於該電容之下部電極的高度,最常見的約為1〇至 2·0微米。由於在焊墊區Α2”中溝渠155所佔的面積甚大, 故前述表面段差仍將存留於模製氧化物層19〇的表面。 請參考圖4-9與4-10,在模製氧化物層190中形成一對孔 195與196,以產生該電容器208之下部電極(圖中的代 號210)。在一高度整合的記憶裝置中(諸如具有256百萬位 元組(MB)容量者),此種孔的大小可能為直徑約〇_25微米 。考慮到在諸如層190之類的一模製氧化物層中使用習知 的抗姓劑遮罩圖樣化如此精細的大小及間距的困難度,故 -16- 本紙張尺度適用中國國家標準(CNS) A4規格(210X 297公釐) 574740 A7 ______B7 五、發明説明(13 ) 孔195與196最好係利用多晶矽構成的一硬遮罩2〇〇形成。 硬遮罩200最好係延伸覆蓋於焊墊區A2,之上,以保護A2, 區中的模製氧化物層190在孔的蝕刻過程中不致受蝕刻。 在模製氧化物層190中形成孔的圖樣195與ι96之後,最 好在整個組件表面上沈積厚度1000至5〇〇〇埃的多晶石夕。為 使該多晶矽導電,故以一高濃度雜質摻入該多晶矽中。圖 4-10中顯示此沈積膜2〇1。 請參考圖4-11,其中在該組件上執行了一蝕刻程序(諸 如一化學機械研磨程序),以孤立出單元區Ai中的下部電 極210。在此過程中,最好已將模製氧化物層19〇上的硬遮 罩層200及摻雜的多晶矽膜2〇1移除。 在元成該#刻程序後’孔195與196的侧壁及底部,以及 -前述焊墊區A2”中凹陷處内最好皆存留有多晶矽。此多晶 石夕形成一第一虛設圖樣220,用以形成該焊墊結構。為防 過度#刻(其可能將第一虛設圖樣2 2 〇完全移除),故必須 適當控制多晶矽的蝕刻量,以在模製氧化物層19〇之凹陷 區中留存所需量的多晶矽材料。 請參考圖4-12,接著可將模製氧化物層19〇 (代表性厚度 為1.0至2微米)利用一濕式蝕刻劑(諸如hf)移除。由於蝕刻 停止層185不·會受HF移除,故模製氧化物層190所覆蓋之 材料即可受其保護,免於HF蝕刻程序的破壞。在完成該 HF蝕刻程序後,如圖4-12中所示,下部電極210完全暴露 於單元區A1中,而由於該第一虛設圖樣22〇的遮罩作用, 使焊墊區A2”内的模製氧化物層190中產生了 一第二虛設圖 -17- 本紙張尺度適用中國國家標準(CNS) A4規格(210 X 297公釐) 574740 A7 B7 五、發明説明(14 ) 樣230。由於濕式钱刻為各向同性(is〇tr〇picai)者,故該第 二虛設圖樣230之側壁係受到部分蝕刻,使該第一虛設圖 樣220部分受到底部掏空。然而,該第二虛設圖樣23〇側壁 厚度的縮減最好僅為1 ·〇至2微米,較之該第二虛設圖樣 230的代表性1〇〇微米xl〇〇微米面積而言應為無關緊要的。 接著,在該電容器之下部電極21〇上形成一電容介電層(未 顯示)。 請參考圖4-13,為形成該電容器的一上部電極24〇,如 圖4-1 3中所示,有一多晶矽層沈積於該組件的整個表面上 。在該焊墊區Α2”中,形成了多晶矽以完全覆蓋該第一虛 設圖樣220以及該第二虛設圖樣23〇。請參考圖仁14,接著 最好是利用微影蝕刻技術圖樣化該上部電極24〇。在此程 序中,焊墊區Α2”内最好能形成一第三虛設圖樣25〇。接著 ’利用化學汽相沈積(CVD)沈積一第四層間介電質28〇, 覆蓋於該組件整個表面上,然後再利用一化學機械研磨 (CMP)或回蝕程序將其整平。 此時,如圖4-15中所示,可在單元區八丨中形成一金屬互 連層及一裝置接點栓之孔(未顯示)。為產生焊墊區Α2”内 的焊墊350之焊墊結構,形成了複數個焊墊接點栓295的複 數個孔。焊墊接點栓295的孔最好係形成一環狀或一網目 。但應留思’當一焊塾接點孔的深度增加時,欲使其孔之 圖樣形成一網目將愈形困難。 如圖4-16到4-18中所示,由於焊墊接點栓之孔的深度縮 減(諸如焊墊區Α2”相對於焊墊區Α2,中孔之深度的縮減), -18- 本紙張尺度適用中國國家標準(CNS) Α4規格(210 X 297公釐) 574740
故在後續程序中形成孔及鎢栓295較之在焊墊區A2,中形成 孔及鎢栓290會更為容易。焊墊接點栓290與295之孔的蝕 刻條件最好為··氧化物層對多晶矽層的蝕刻選擇率高的狀 況,使一蝕刻程序可結束於該多晶矽層。在蝕刻之後,即 最好利用一化學汽相沈積(CVD)程序將焊墊接點栓29〇與 295的孔以鎢填滿。接著,再化學、機械性地研磨或回蝕 所產生組件’從而形成一鎢栓。前述處理程序的結果產生 出堅固焊墊結構的一固定結構。 請參考圖4-16,在形成該鎢栓290與295後,再形成一第 一鋁互連層3 00。接著,再於第一鋁互連層3〇〇之上沈積一 金屬間介電層310,如圖4-17中所示。接著,再於該金屬 間介電層310内形成一接點孔32〇 ,然後再形成一第二鋁互 連層330以產生焊墊350完整的「沙漏」結構。 如圖4-1 8中所示’有一鈍化層340沈積於該組件的整個 表面上,以保護所製成的IC。再最後一步驟中,係以在焊 墊位置處的選擇性蝕刻將焊墊350暴露出來,以產生一抗 拒剝離焊墊350。 依據第二項具體實施例,如圖4·1至4-18中對焊塾區A2” 的處理,較小的焊墊接點孔深度,使該焊墊接點孔以及該 鎢填充栓295皆能更輕易且均勻地形成。如同在先前焊墊 區Α2’的製造步驟一般,在焊墊下方的虛設圖樣可與用以 建構該電容器的程序步驟於相同時間且在相同程序步驟中 輕易形成,即不需額外程序步驟,或頂多僅需最小數量的 額外步驟。 -19- 本纸張尺度適用中國國家標準(CNS) Α4規格(210 X 297公釐) 574740
圖5顯不根據本發明之第三項具體實施例的焊墊結構。 在圖5所示的具體實施例中,不似第二項具體實施例,在 該第二層間介電質140内並無溝渠的形成。在此項具體實 施例中’彳在該焊塾35G的下方建構一電容器圖樣,以作 為-虛設圖樣,而不需如圖4_3之溝渠155中的虛設圖樣, 從而消除相關的後續凹陷處理作用。另外,在此具體實施 例中,該電容器的下部與上部電極21〇與24〇分別可於該單 凡區A1以及該焊墊區A2中同時形成。在該下部電極以❽形 成之後,該電容器之上部電極24〇形成之前,有一電容介 電層(未顯示)形成。形成於該焊墊區A2中的該電容器圖樣 為一虛設圖樣,且其並不需作為一電容器使用。圖5令顯 不焊墊區A2内有一焊墊與二虛設電容圖樣。然而,此種 電容器的範例性大小可為〇·2微米至〇·5微米,而該焊墊的 代表面積則為100微米X 1〇〇微米。在此種狀況下,在該焊 墊下方可能需要許多此種虛設電容圖樣,以提供所需的固 定作用。 本發明所提供之焊墊將可防止焊墊於後續製造程序步驟 中剝離或分層剝離。另外,位於焊墊35〇下方的該多層虛 設圖樣使所產生結構可減緩線路焊接過程中導入的應力。 因此,利用本發明的各種具體實施例,即可形成一堅固的 焊墊結構、簡化製造程序並降低製造成本。 圖6顯示根據本發明之第四項具體實施例的焊塾結構。 在此項具體實施例中,一(或多個)鎢栓355可能具有矩形 、楔形或甚至實心立方體的特性。栓355的特定形狀及/或 -20-
