Description
堆積/スパッタ比は堆積の増大に伴って増大し、スパッタリングの増大に伴って減少する。D/Sの定義で使用されているように、「正味堆積レート」とは、堆積およびスパッタリングが同時に生じている場合に測定される堆積レートのことである。「ブランケットスパッタレート」は、堆積ガスなしでプロセスレシピが運用される場合に測定されるスパッタレートであり、プロセスチャンバ内の圧力は、堆積時の圧力、およびブランケット熱酸化膜で測定されたスパッタレートに調整される。
E/D≡(ソースのみの堆積レート)−(正味堆積レート)/(ソースのみの堆積レート)
であり、これはスパッタリングの増大に伴って増大し、堆積の増大に伴って減少する。E/Dの定義で使用されているように、「正味堆積レート」はまた、堆積およびスパッタリングが同時に生じている場合に測定された堆積レートのことをいう。「ソースのみの堆積レート」は、しかしながら、スパッタリングなしでプロセスレシピが運用される場合に測定される堆積レートのことである。本発明の実施形態はD/S比に関してここでは説明されている。D/SおよびE/Dは正確な逆数ではないが、これらは逆相関しており、両者間の変換は当業者に理解される。
