Description
別の実施形態では、軽減システムが開示される。軽減システムは、第1の端部および第2の端部を有する本体を含むプラズマ源を含み、第1の端部は、フォアラインに結合するように構成され、第2の端部は、導管に結合するように構成される。プラズマ源は、本体内に配置された電極と、本体の第1の板上に配置された第1の複数の磁石と、本体の第2の板上に配置された第2の複数の磁石とをさらに含む。
別の実施形態では、真空処理システムが開示される。真空処理システムは、真空処理チャンバと、プラズマ源であって、外側エッジおよび内側エッジを有する第1の板、第1の板に平行であり、外側エッジおよび内側エッジを有する第2の板、第1および第2の板の外側エッジ間に配置された外壁、第1および第2の板の内側エッジ間に配置された電極、第1の板上に配置された第1の複数の磁石、ならびに第2の板上に配置された第2の複数の磁石を含むプラズマ源とを含む。
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、いくつかを添付の図面に示す実施形態を参照することによって、上記で簡単に要約した本開示のより具体的な説明を得ることができる。しかし、本開示は他の等しく有効な実施形態も許容することができるため、添付の図面は、本開示の典型的な実施形態のみを示し、したがって本開示の範囲を限定すると見なされるべきではないことに留意されたい。
図1Aは、軽減システム193内で利用されるプラズマ源100を有する真空処理システム170の概略側面図である。真空処理システム170は、少なくとも、真空処理チャンバ190およびプラズマ源100を含む。軽減システム193は、少なくとも、プラズマ源100を含む。真空処理チャンバ190は概して、堆積プロセス、エッチングプロセス、プラズマ処置プロセス、事前洗浄プロセス、イオン注入プロセス、または他の集積回路製造プロセスなど、少なくとも1つの集積回路製造プロセスを実行するように構成される。真空処理チャンバ190内で実行されるプロセスは、プラズマ支援型とすることができる。たとえば、真空処理チャンバ190内で実行されるプロセスは、シリコンベースの材料を堆積させるプラズマ堆積プロセスとすることができる。
プラズマ源100は、真空処理チャンバ190から出るガスおよび/または他の材料上で軽減プロセスを実行するために利用され、その結果、そのようなガスおよび/または他の材料を、より環境および/またはプロセス機器に優しい組成物に変換することができる。プラズマ源100の詳細については、以下でさらに説明する。
プラズマ源100と排気導管194との間には、プラズマ源100からくる排気の温度を低減させるために、排気冷却装置117を結合することができる。一例では、排気冷却装置117は、軽減システム193の一部である。
図1Bは、一実施形態によるプラズマ源100の側面図である。プラズマ源100は、真空処理チャンバ190の下流に配置することができる。プラズマ源100内で生成されるプラズマは、真空処理チャンバ190からくる排出物中の化合物にエネルギーを与え、かつ/または排出物中の化合物を部分的もしくは完全に解離し、排出物中の化合物をより環境に優しい形態へ変換する。一実施形態では、高密度のプラズマを生じさせる能力のため、プラズマ源100は、処理チャンバの上流に配置された遠隔プラズマ源として、分子種または原子種、高密度のプラズマなどのプラズマの生成物を処理チャンバ内へ送出するように作用することができる。
