Description
[0094]本発明の実施形態によるガス分配とプラズマ生成システムの実施形態には、前駆物質を堆積チャンバへ分配するシャワーヘッドが含まれるのがよい。これらのシャワーヘッドは、二つ以上の前駆物質が堆積チャンバ内で混合するまで接触せずに独立してシャワーヘッドに流れることができるように設計されるのがよい。シャワーヘッドは、また、プラズマがフェースプレートの後ろだけでなく堆積チャンバ内に独立して生成することができるように設計されてもよい。シャワーヘッドのブロッカープレートとフェースプレートの間に生成される独立したプラズマは、反応性前駆物質種を形成するだけでなく、フェースプレートに近い洗浄化学種を活性化することによってシャワーヘッド洗浄プロセスの効率を改善するために用いることができる。二つ以上の前駆物質を堆積領域に独立して流れるように設計されたシャワーヘッドについての詳細は、更に、2005年1月22日出願の“MIXINGENERGIZED AND NON-ENERGIZED GASES FORbSILICONNITRIDE DEPOSITION”と称するJungらによる米国特許出願第11/040,712号に見出すことができ、この全体の内容は全てのために本願明細書に含まれるものとする。
