Description
[シャワーヘッド13]
図2は、第1実施形態に係るシャワーヘッド13の上部電極13Bの平面図である。図3は、第1実施形態に係るシャワーヘッド13の断面図である。図3は、具体的には、図2のI-I断面図である。
[シャワーヘッド113]
図4は、第2実施形態に係るシャワーヘッドの上部電極113Bの平面図である。第2実施形態に係るシャワーヘッドは、第1実施形態に係るシャワーヘッド13の上部電極13Bに換えて、上部電極113Bを備える。
[シャワーヘッド213]
図5は、第3実施形態に係るシャワーヘッドの上部電極213Bの平面図である。第3実施形態に係るシャワーヘッドのクーリングプレートは、第1実施形態に係るシャワーヘッド13の上部電極13Bに換えて、上部電極213Bを備える。
プラズマ処理空間10sにおいて、プラズマが発生すると、プラズマからの熱が上部電極に入熱する。上部電極にプラズマからの熱が入熱すると、上部電極の温度が上昇する。上部電極の温度が上昇すると、上部電極の劣化が進み、交換周期が短くなる。したがって、上部電極の温度上昇を抑制するために、クーリングプレートにより上部電極を冷却する。
クーリングプレートの一つの貫通孔に対する上部電極の貫通孔の数について、クーリングプレートと上部電極との間の異常放電について評価を行った。
本実施形態に係るシャワーヘッドは、クーリングプレートの貫通孔一つに対して、上部電極の貫通孔を少なくとも二つ備えることにより、クーリングプレートと上部電極との間の異常放電の発生を抑制できる。
本実施形態では、上部電極の上面に凹部を設けたが、凹部を設ける場所については、上部電極に限らない。例えば、クーリングプレートの下面、すなわち、上部電極と接続する面、に凹部を設けてもよい。
