Description
例えば、上記実施の形態では、プラズマ処理装置1に対して1つの押圧機構100が設置され、当該押圧機構100の形状は平面視において同軸導波管50を囲むような略円環形状であると説明したが、本発明に係る押圧機構100の形状・構成はこれに限られるものではない。以下では、本発明の他の実施の形態として図面を参照して押圧機構100の他の形状・構成について簡単に説明する。
図4に示すように、本形態に係る押圧機構100は、平面視において同軸導波管50を中心とし、同心円状の複数のリング形状となっており、内側から順に、当該同軸導波管50を囲む3つの略円環形状の機構100a、100b、100cから構成され、それぞれの径は異なっている。それぞれの機構100a、100b、100cはそれぞれ独立した構成であり、それらの内部空間への流体の供給は各流体供給機構130a、130b、130cによって独立して制御される。即ち、各機構100a〜100cごとにヒータ80、冷却ジャケット44、遅波板43、スロット板42にかかる押圧荷重を調節することができる。
