1250205 玖、發明說明: 【發明所屬之技術領域】 本發明係有關於一種化學組成物,用以移除半導體光製 程中各種蝕刻、灰化和/或離子注入方法令產生或殘留的侧 壁冋分子或餘刻殘留物,以及底金屬層钱刻後之變性光感 金屬殘留物(以下以殘留物簡稱之)。相較於傳統化學產物' 該化學組成物實質上具有數種顯著優點,包括但不限於以 下幾點:此化學組成物不會造成底層紐或損害,也因為 低揮發損失所贿用上較為崎。使用此化學組成物的殘 留物清潔程序不需如傳統光製程中_聽舰潤步驟。 此外,此化學組成㈣魏友善’實f上不會對人體造成 毒害’且同時適用於|g線及銅線製程。 【先前技術】 傳統上半導體製程由-系列用來在基材上形成導體金 屬層圖形的步驟所組成,包括在導體層上提供一光阻敍刻 P且擔遮罩圖形,用來保護各式钱刻劑對導體金屬層的蝕 刻。利用餘刻步驟形成-預定的導體金屬層圖形後,此蝕 刻阻擋遮罩接著必須在接下來的清潔步驟中移除。 因此’在用來移除殘留物的傳統濕式清潔程序中,常利 用各式有機胺類化合物等化學組成物,特別是如單乙醇胺 的絲醇胺(alkanol amines)及各種有機溶劑。然而,上述 統胺類化合物並無法完全移除在乾_、灰化或離子植入 步驟中因暴露在電絲刻氣體或離子束中而變質的殘留 7 1250205 物。 值得注意的是,進來半導體製程的革新已快速進展到更 高的積集度,對触刻阻擋遮罩的製程要求也提高到更高的 溫度:120-140°C,而在乾蝕刻及灰化的情形下,製程同時 要求高溫度、高壓力以及更高劑量的電漿。此等嚴苛的製 程條件通常會對殘留物的完全清除造成妨礙,特別是有機 金屬以及金屬氧化物的殘留物。因此,近來發展的半島體 製程對創新的殘留物移除化合物的需求更為殷切,以期能 充分移除在南溫度、南壓力以及南劑量的電漿製程條件下 所形成的殘留物。 為了能充分移除在南溫度、南壓力以及高劑量的電聚製 程條件下所形成的殘留物,包含1·羥胺(hydr〇Xyl amine)、 2·烷基醇胺(alkanol amines)、3·去離子水以及包含或未含抗 腐蝕劑的多種化學組成物已經被提出。例如日本公開專利 號碼:1992-28986、1994-266119 以及 1997-96911 等文獻中 所揭露用來移除上述殘留物的一些化學組成物。 然而’羥胺基(HA-Based)的組成物在製程溫度低於5〇 C時,在移除殘留物的性能上有不夠充分的傾向,因此此 等組成物只能應用在製程溫度高於7(rc的製程中,也因此 造成顯著的揮發損失。在任何情形下,只要揮發損失超過 百刀之十,此組成物的殘留物移除表現能力也明顯受到侷 限。除此以外,上述經胺基(HA-Based)的組成物同時需要 個別的溶舰潤步驟來避免導體底金屬層的雜或電性的 改變。值得注意的-點,當上述金屬層是由銅金屬所形成 8 1250205 時,由於銅金屬具有腐紐的本質,使 的組成物無法用來移除其殘留物。 工'ased) 因此’在S程上對於可销程溫度低於耽賴程條件 製程溫度高於机的製程條件下具 有L揮發缺,在長時剛㈣下卿發速率小於百分之 同時適用於紹線與鋼線製程的新型化 學組成物有 因此,本發明的主要目的即在於提 物=善料傳統敎賴-賴_財=|充成 此所提出的化學組成物在移除殘留物方 ΪίΠπί特別對有機金屬以及金屬氧化物的 並可同__齡如及_銅^^1 成 害’ =:成:r揮發速率,別= ;潤,i提供一穩定並經濟的清潔製程。除此之 ^二,友麵化學組級紐實騎人體無危害並對 裱境安全。 【發明内容】 夂供—種化學組成物,肋移除半導體光製程中 八、灰化和/或離子注人方法中產生錢留的側壁高 侧殘留物’以及底金屬層_後之變性光感金屬 2甘Γ學組成物包含:至少—與金屬共價鍵結之有 機文,/、中該有機酸以下列化學式①與⑼代表, 1250205
