description PROBLEM TO BE SOLVED: To provide plasma processing chamber coatings that have longer lifetimes and better protection against corrosive process chemicals.SOLUTION: Aluminum 101 forming an interior surface of a plasma processing chamber is coated with a multi-layer film comprising a layer 102 of aluminum oxide (AlO), a layer 103 of stabilized zirconia (YSZ) and a layer 104 of yttrium aluminum garnet (YAG).SELECTED DRAWING: Figure 1 【課題】寿命が長く尚且つ腐食性プロセス化学剤に対する保護にいっそう優れたプラズマ処理チャンバのコーティングを提供する。【解決手段】プラズマ処理チャンバの内表面であるアルミニウム101を、酸化アルミニウム(Al2O3)の層102、安定化されたジルコニア(YSZ)の層103、イットリウム・アルミニウム・ガーネット(YAG)の層104の多層膜でコーティングする。【選択図】図1
