經由一設置在含鎢的電極層上的氮化矽覆蓋層以形成一柵 電極柱(例如利用等離子體#刻法)會以相應之柵接點 金屬連接線。 ’、 經上述方式形成的柵電極柱通常還要接受熱處理,以便同 時在露出的側壁上形成一很薄的氧化層,並經由特定的相 位轉換或晶粒生長使電阻降低。以這種方式在聚矽層側壁 上形成的氧化層可以改善電晶體的漏電情況,並作為後續 之LDD(Lightly Doped Drain)植入的間隔襯墊(Spacer)、^ LDD植入可經由定義的柵長調整電晶體參數。在业型加埶 =度。_-,80。〇下進行的金屬相位轉換可以使金屬的 電阻降低,同時在栅極金屬上會產生旺盛的晶粒生長 況0 現今使用的半導體元件製造 進行1 0 0 0 -- 1 080 °c的熱處理 處理方式會產生以下說明的 方法是在柵電極柱形成後立刻 ’緊接著就是植入LDD。這種 問題。 使用矽化鎢(WSix)會將位於下太沾取仏院 電極柱被蝕刻得非常光滑的側面:::層熔入,造成在柵 體技術進展到小於17〇nm後,由於長此出晶粒。在將來半導 在接點蝕刻時可能會受到腐飿,;"〜一 ▲側面長出的晶粒 接點產生短路。 因此可能會與相鄰的金屬
