Description
A7 經濟部中央標準局員工消費合作社印製 B7 _五、發明埤明(1 ) 發明背景 發明領域 本發明係有關於Al-Cu合金電導體之板電阻的穩定性。 習知技術説明: 由於AI-Cu低電阻的優點,已用於VLSI裝置中作為電 導體。但是,Al-Cu深具化學活性且在450°C以上,當加熱 時可與金屬產生反應。為了克服此項問題,已在Al-Cu合金 及其他金屬之間加以TiN作為擴散障壁。但是,如旋上玻璃 (spin-on-glass,SOG )固化,燒結,鋁再回流等的A1-Cu/TiN柱沉積熱處理可增加如Al-0.5%Cu ( 600nm厚)/TiN (50nm厚)的板電阻至約50 %。此時裝置產生嚴重的問 題,其中在該裝置中SOG (有機或無機)固化及鋁再回流 用於介質平板化,及製造期間的穿口充塡。 在大部份一TiN障壁性質改進有關的習知技術中,其目 的在於防止鋁向主動矽裝置或鎢穿口擴散。在習知技術 中,可在TiN沉積期間,由沉積參數的最適化而達成TiN障 壁改進,例如在沉積期間導入氧氣流,或改變基體溫度, 或加一基體電壓之偏壓。已提出一些柱(post )沉積處 理,如熱韌化及暴露至空氣中。 在TiN沉積期間,因為氧氣可污染鈦濺射目標勿,形成 鈦氧化物粒子,且增加TiN的板電阻,因此不必加入氧劑 量。改變沉積溫度可能導致TiN其他性質的改變,如壓力或- —3 一 --------1--T 1¾衣------1ΤΊ (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標隼(CNS ) Α4規格(210X 297公釐) 經濟部中央標準局員工消費合作社印製 301031 a7 B7_ _ 五、發明説明(2 ) 粒子大小,而使得很難同時將這些參數最適化。加入基體 偏壓導致TiN層的離子衝擊,此可能導致輻射而破壞現存的 裝置。柱沉積處理包含其他處理步驟,因此增加處理循環 時間。而且,TiN的熱韌化(密化)可在Al-Cu合金不出現 的接觸位準中完成。本案之申請人已得知將TiN暴露於空氣 中24小時,並不會改進障壁性質。 發明概述 依據本發明,在金屬擴散障壁層(最好為TiN)沉積之 後,使用電漿束(最好為氧)而使導體,如鋁,銅及其合 金,如Al-Cu合金的電阻穩定,因此TiN的障壁特性跟著改 進。結果在熱循環之後,Al-Cu/TiN的板電阻仍然一樣,此 程序的優點為,因為在TiN沉積期間,電漿處理不會受到影 響,不會產生上述污染/粒子問題。而且,因為電漿為低能 量離子束,足以從金屬擴散障壁層之表面區域中約3〇至50 %的氧中提供,其只與TiN的表面區域作用至約50埃。結 果,大部份的TiN仍具金屬性,且TiN的板電阻並不會產生 具影響性的改變。因一方面,在氧電漿的例子中,如確信 在TiN表面處的表面方域確信為Ti-Ν-Ο層,係由氧電漿/TiN 作用所致,且其厚度足以封鎖Al-Cu合金及TiN之間的反 應,且同時薄得足以允許電流穿隧。而且,可在電阻餘燼 室中方便地進行電漿處理,此可用於製造環境中。總餘燼 時間(電漿處理時間)可極短(少於一分鐘),所以產量 (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準(CNS ) A4規格(UOXW·?公釐) A7 B7 經濟部中央標準局貝工消費合作社印製 五、發明説明(3 ) 的減少有限·。如果製程有必要整合,可將一分開的氧電漿 室加入現存的TiN濺射系統中。 簡言之,本發明的製程需提供一基體,一種使金屬導 體及其他金屬間的反應達到最小,而使得當熱處理時,導 體的板電阻中的改變為最小的方法,該方法包含提供—基 體,最好此基體為介質,金屬,或半導體種的一種。—金 屬擴散障壁層,最好為TiN,TiW或TiWN中之一,且最好 厚度介於約10奈米(nanometer)至約1〇〇奈米之間,該金 屬擴散障壁層沉積在基體上,其中沉積方法為濺射,電子 束蒸發’或化學蒸汽沉積中的一種方法。金屬擴散障壁層 的暴露表面應用電漿加以處理,該電漿最好為氧電漿,氧 化氮電漿,或含氧物種之電漿中的一種電漿。然後,一電 導體,最好為鋁,鋁—金屬合金’銅,銅—金屬合金中的 一種’然後,且最好厚度介於約1〇〇奈米至約12〇〇奈米之 間,該電導體沉積在金屬擴散障壁層中經電漿處理的表面 上。該層可形成如基體上的毯子或連續膜中之一。然後, 可對電導體或障壁層上圖樣。 較佳實施例説明 首先在一些二氧化矽基體上沉積50nm (奈米)厚的 Tin層。然後,一些含丁比層的基體在電阻餘燼室中使用單 一,雙或三Gasonic程序,以進行氧電漿處理,並進行 Branson烘調30至60分鐘,且不產生餘燼(ash)。 •裝------訂------ (諳先聞讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標隼(CNS > A4規格(210X297公釐) 經濟部中央標準局員工消費合作社印製 A7 B7 五、發明説明(4 ) Branson烘調方法的條件為: 氧氣 650SCCM (標準立方公分) RF功率 1000瓦 壓力 1.15Torr 時間 (見下圖) Gasonic程序的條件為: 氧氣 5SCCM 二氧化氮 0.5SCCM 壓力 1.75Torr RF 功率 lOOOwatt 時間 50秒 然後,由上列各程序,處理時間低於表列而含有餘燼 的晶圓及不含餘燼的晶圓經濺射處理之後,覆上一層 600nm厚的A1-0.5 % Cu,量測晶圓的板電阻。在450°C下經 過一小時的SOG固化熱處理之後,再度量測晶圓的板電 阻’且與SOG固化之前所量測的板電阻比較。下表列出電 阻增加(RI)的百分比: ---------丨-裝------訂------ri (請先閱讀背面之注意事項再填寫本頁) 餘爐 供調 RI ( TIN ) RI ( Al-Cu/Tin ) 時間 單 Gasonic 10.6 0.35 50秒 雙 ,, 16.3 0 100” 二 ” 35.4 1.3 150” 30 分鐘Branson 8.4 1.3 30分 本紙張尺度適用中國國家橾準(CNS ) A4規格(210X297公釐) A7 B7 五、發明説明(5 ) 60 ’, ,, 無餘爐 11.4 1.5 10.5 60’ 由表中可看出與沒有餘燼的情況比較起來,電槳處 或餘燼,導至電阻增加一不可忽略之數値。 雖然上文中已應用較佳實施例説明本發明,對於網孰 於本技術者可隨即了解該實施例的多項變動及修改方法了 因此由習知技術的觀點上看來,所附的中請專利範圍可用 於包含所有此類變動及修改方法。 ------''----裝-- f請先閱讀背面之注意事項再填寫本頁) 訂
