200528394 九、發明說明: 【發明所屬之技術領域】 本發明係關於矽鈷膜及其形成法、形成用組合物。更詳 細地,係關於MOS型半導體裝置之製造中,尤其係關於具 有矽化物化之閘極電極與源極·汲極區域之半導體裝置之 製造中有用之石夕銘膜形成用組合物、石夕錄膜及其形成方法。 【先前技術】 在使半導體裝置高度集成化之圖案細微化同時,閘極電 極也需要低電阻化。作為使閘極電極低電阻化之方法,已 知藉由SALICIDE (自我對準之石夕化物(Self-Aligned Silicide))法使 閘極電極矽化物化之方法。 於矽半導體中,為了藉由配線用金屬材料與矽之界面之 功函數形成歐姆接點,大量使用由Co、Ni、Au、Ag、Ti、 Pd、A1等其他金屬與矽化物等將矽層表面重整之方法。此 外,考慮到矽化物本身之比電阻、與矽之晶格常數之匹配 性,大多使用鈷的矽化物作為矽化物(參照日本專利第 3382743號公報)。
此等矽化物通常係藉由真空蒸鍍法、濺射法、電裝CVD
(化學蒸鍍(Chemical Vapor Deposition))法、熱 CVD法、光 CVD
法、MOCVD法(有機金屬CVD (Metal organic CVD))等真空製程 將Co、Ni、Au、Ag、Ti、Pd、A1等金屬膜層壓在矽膜上後, 高溫處理而石夕化物化之方法所得到之普通石夕化物(來日g J
