金屬間介電層6的形成、對接觸窗孔7的多晶矽插塞 8 a、8 b的埋入、金屬間介電層9的形成、接觸窗孔 1 0以及貫穿孔1 1的形成。 在圖3爲了防止來自配線等的對矽基板之重金屬污 染,在接觸窗孔1 〇、貫穿孔1 1內形成高熔點材料膜 1 2當作阻障(Barrier)膜。高熔點材料膜丨2例如爲利用潑 鍍(Sputtenng )法或CVD法沉積厚度1 〇 ηιη的欽( τ丨)膜、厚度1 〇〇nm的氮化鈦(T i N)膜之疊層 構造。在高熔點材料膜1 2與矽基板1以及多晶矽插塞 8 b的界面’利用由之後加入的熱處理工程中的化學反應 形成金屬矽化物(Silicide )層1 5。例如當高熔點材料膜 1 2爲T i §吴、τ i N膜的暨層構造時形成砂化欽層,當 高熔點材料膜1 2爲鈷膜與T i N膜的疊層構造時形成矽 化銘層。 在高熔點材料膜1 2的形成後,利用化學氣相蒸鍍 (C V D )法沉積W膜1 3,在接觸窗孔內埋入W膜 1 3 ’形成W插塞1 4。沉積於金屬間介電層9上的高熔 點材料膜1 2以及W膜1 3利用化學機械硏磨(C Μ P ) 法’僅殘存W插塞1 4來進行硏磨除去,然後,平坦化金 屬間介電層9的表面。 在圖4於金屬間介電層9上利用濺鍍法或C V D法形 成Mo膜16a、W膜16b、Mo膜16a。沉積的膜 厚爲例如Mo膜16a 10nm、W膜16b 1〇〇 nm、Mo膜]_6a l〇nm。因Mo膜的電阻與W膜 本紙張尺度適用中國國家榡準(CNS ) A4規格(210X297公釐) (請先閲讀背面之注意事項再填寫本頁) Γ
