Abstract
Description
本発明の実施形態は概して、半導体処理チャンバのための処理キット及びキットを有する半導体処理チャンバに関する。より具体的には、本発明の実施形態は、物理気相蒸着チャンバにおける使用のためのカバーリング、シールド及びアイソレータを備えた処理キットに関する。
物理気相蒸着(PVD)又はスパッタは、電子デバイスの製造において最も一般的に用いられる処理の1つである。PVDは真空チャンバ内で行われるプラズマ処理であり、負のバイアスをかけたターゲットを比較的重い原子(例えば、アルゴン(Ar))を有する不活性ガスのプラズマ又はこのような不活性ガスを含むガス混合物に暴露する。不活性ガスのイオンがターゲットに衝突することによりターゲット材料の原子が弾き出される。弾き出された原子は、チャンバ内に配置された基板支持台座部上の基板上に堆積膜として蓄積される。
Claims (15)
