Abstract
Description
分野
本開示の実施形態は、一般に、処理チャンバを洗浄するための装置及び方法に関する。
化学気相堆積(CVD)プロセス中に、反応ガスはチャンバの内面に堆積する組成物を生成する可能性がある。これらの堆積物が蓄積すると、残留物が剥がれ落ち、将来の処理ステップを汚染する可能性がある。そのような残留堆積物はまた、堆積均一性、堆積速度、膜応力、粒子性能などの他の処理条件に悪影響を与える可能性がある。
本開示の実施形態は、一般に、処理チャンバを洗浄するための装置及び方法に関する。一実施形態では、処理チャンバは、チャンバ本体と、チャンバ本体内に配置された基板支持体とを含む。基板支持体は、表面と、表面に接続された側面とを含む。処理チャンバは、基板支持体上に取り外し可能に配置された基板支持体カバーをさらに含む。基板支持体カバーはフッ化物材料を含み、処理チャンバ内の処理領域に露出している。
本開示の上記の特徴を詳細に理解することができるように、上記で簡単に要約した本開示のより具体的な説明を、実施形態を参照することによって行うことができ、そのいくつかを添付の図面に示す。しかし、添付図面は例示的な実施形態のみを示すものであり、したがって、本開示の範囲を限定すると見なすべきではなく、その他の等しく有効な実施形態も許容され得ることに留意されたい。
本開示の実施形態は、一般に、処理チャンバを洗浄するための装置及び方法に関する。一実施形態では、基板支持体カバーは、フッ化物コーティングでコーティングされたバルク部材を含む。基板支持体カバーは、洗浄プロセス中に処理チャンバ内に配置された基板支持体上に配置される。フッ化物コーティングは洗浄種と反応しない。基板支持体カバーは、基板支持体が洗浄種と反応するのを防ぎ、チャンバ部品に形成される凝縮の減少をもたらし、これにより、後続のプロセスでの基板の汚染が減少し、処理条件の変更又はドリフトが防止される。
