Abstract
【解決手段】バッフルプレートアセンブリは、バッフルプレート250、リング256、および支持部材254を備える。バッフルプレート250は、外径を有し、基板処理システムのシャワーヘッドアセンブリのシャワーヘッドを通じてガスを分配するように構成される。ガスは、シャワーヘッドアセンブリのステム252から受け取られる。リング256は、内径を有し、シャワーヘッドアセンブリのリング溝258に配置されるように構成される。その内径は、バッフルプレート250の外径より大きい。支持部材254は、バッフルプレート250からリング256に延びる。リング256および支持部材254は、シャワーヘッドの天板と底板との間の位置にバッフルプレート250を保持する。
