Description
本発明の一実施の形態を、実施例1を用いて説明する。図1は、実施の形態に用いる液相エッチング装置を説明する図である。以下、図1を参照しながら、実施例1に係るエッチング装置の概略を説明する。真空チェンバー10には真空を作り出すための真空ポンプ20が接続されている。真空チェンバー10内に、保持台40と複数のノズル50が設置される。保持台40は、固体もしくは固体の集合体あるいはジェル状の物体などの被処理物30を保持できる。ノズル50は、所望の液体を供給する液体供給装置60に接続されており、被処理物30に化学反応性の液体70を粒子状にして吹き付けることが出来る。被処理物30をエッチング出来る種々の液体70の内から、それぞれの被処理物に適した溶剤を選択して使用する。
ズル50からおよそ時速1000km以上の速度で液体70を吹き付ける。吹き付けられた液体が被処理物表面31に付着すると同時にエッチングが行われる。被処理物表面31と液体70の関係で界面活性剤を利用する事によって液体が被処理物表面31に行き渡り均質なエッチングに効果を発揮する。被処理物表面31での液体70のヌレ性が悪い場合には、界面活性剤を非処理物表面に吹き付けることによって、液体70が被処理物の表面31の全体に行き渡り、エッチングが均一に行われる。
一部の液体成分が高いエネルギーを得てプラズマ化する事がある。このようにして発生するプラズマは被処理物表面を活性化させ、エッチング速度を一層加速させる効果がある。
