Abstract
Description
本発明の実施形態はプラズマ処理装置の分野に関し、特にプラズマ処理チャンバの部品用耐プラズマコーティングに関する。
真空プラズマ処理チャンバは、太陽電池及び集積回路等のデバイス製造間におけるプラズマ処理に使用される。プロセスガスのプラズマを生成するためにプロセスガスに電場が印加される間、プロセスガスは処理チャンバ内へ流される。稼働コストを減らすために、処理プラズマに曝露されるプラズマ処理チャンバ内の部品の寿命は、部品が耐プラズマ性をもつように設計することによって延びる。本明細書内で使用されるとき、「耐プラズマ」という語句は、プラズマ処理チャンバ内で生成されるプラズマ処理条件に曝露される時に浸食及び腐食に対して抵抗力をもつことを言う。耐プラズマ部品は現在、バルク材から、又は基板上に保護コーティングを熱溶射することによって作られる。
