Description
すなわち、投入したマイクロ波によって、チャンバー内に節・腹を有する振動電界が複数個形成される。その結果、当該電界の腹で生じる強電界により形成されるプラズマも複数個に分散されてしまう。よって、プラズマ気相反応を行うチャンバー内の領域に腹が一つのみ形成される電界分布を実現すれば、安定な強いプラズマをその領域にのみ形成することができるという発想に至った。
すなわち、本発明に係るマイクロ波プラズマ気相反応装置は、マイクロ波を伝送するための導波管を備えたマイクロ波プラズマ気相反応装置であって、マイクロ波によるプラズマ生成を行うチャンバーを備え、前記チャンバーの内壁は、前記導波管に対向する側の下面の径が当該導波管側の上面の径よりも小さくしてカットオフ寸法未満となるようにテーパー状に構成され、前記マイクロ波プラズマ気相反応装置は、さらに、前記チャンバーの下面から立設された金属ロッドを備え、当該金属ロッドに金属鍔を設けることを特徴とするものである。
さらに、チャンバーの下面から立設された金属ロッドを備え、当該金属ロッドに金属鍔を設ける。金属ロッドに金属鍔を設けることにより、金属鍔から上部において電界強度を確実に強めることができ、強いプラズマを確実に形成することができる。また、被処理物(試料)に対してプラズマ処理を行う場合には、試料を支持する試料支持台を金属ロッドで形成して、適切な位置(高さ)に試料支持台(金属ロッド)を設けることで、その試料支持台の真上で強いプラズマが形成される。
図3〜図5では金属ロッドおよび金属鍔を設けなかったときのシミュレーション結果であったが、金属ロッドおよび金属鍔を設けたときのシミュレーション結果について、図6〜図9を参照して説明する。
