次に、基板処理装置に使用される部材の製造方法の一例について、図2及び図3を参照しながら説明する。図2は、一実施形態に係る基板処理装置に使用される部材の製造方法の一例を示す図である。図3は、図2に示す一実施形態に係る基板処理装置に使用される部材の製造方法を説明するための図である。
3Dプリンタ200を用いて形成したアルミニウムの造形物3及びその表面を陽極酸化処理した酸化膜4のアルミナの状態について、図4を参照しながら説明する。図4(a)は、図2及び図3に説明した通り、3Dプリンタ200を用いて形成したアルミニウムの造形物3及びその表面を陽極酸化処理した酸化膜4のアルミナの状態を示す。図4(b)は、比較例としてアルミニウムの鋳造技術を用いて、鋳型310にアルミニウムの溶融金属320を流して形成したアルミニウムの鋳造物300及びその表面を陽極酸化処理した酸化膜400のアルミナの状態を示す。
図5(a)は、3Dプリンタ200を用いて作製したアルミニウムの造形物3の表面を陽極酸化処理して酸化膜4を被覆した造形物3の耐食性の実験結果の一例を示す。図5(b)は、鋳造技術により作製したアルミニウムの鋳造物300の表面を陽極酸化処理して酸化膜400を被覆した鋳造物300の耐食性の実験結果の一例を示す。「initial」は、初期状態(25℃)の造形物3及び鋳造物300についての耐食性の実験結果を示す。実験の結果、図5(a)の造形物3と図5(b)の鋳造物300とは、同程度の耐食性を有することが分かった。つまり、3Dプリンタ200を用いて作製した造形物3は、鋳型を用いて作成した鋳造物300と遜色ないプラズマ耐性を有する。
図6(a)は、3Dプリンタ200を用いて作製したアルミニウムの造形物3の表面を陽極酸化処理して酸化膜4を被覆した造形物3の絶縁性の実験結果の一例を示す。図6(b)は、鋳造技術により作製したアルミニウムの鋳造物300の表面を陽極酸化処理して酸化膜400を被覆した鋳造物300の絶縁性の実験結果の一例を示す。絶縁破壊電圧(V/mm)は、その値が高いほど絶縁性が高いことを示す。「initial」は、初期状態(25℃)の造形物3及び鋳造物300についての絶縁性の実験結果を示す。「200℃」は、200℃に加熱した後の造形物3及び鋳造物300についての絶縁性の実験結果を示す。
最後に、一実施形態に係る基板処理装置に使用される部材が使用される基板処理装置の一例について、図7を参照しながら説明する。図7は、一実施形態に係る基板処理装置の構成の一例を示す図である。図7に示すプラズマ処理装置1は、容量結合型の装置であり、基板処理装置の一例である。
