Description
本明細書で説明される諸実施形態は、概して、半導体製造で用いられる処理チャンバに関する。より具体的には、上に配置された基板にバイアスをかけるように構成された基板支持アセンブリを有する処理チャンバ、及び基板にバイアスをかける方法に関する。
高アスペクト比のフィーチャーを確実に作り出すことは、半導体デバイスの超大規模集積(VLSI)及び超超大規模集積(ULSI)という次世代に向けた重要な技術課題の1つである。高アスペクト比のフィーチャーを形成する、ある1つの方法では、プラズマ支援エッチング処理を用いて、基板の誘電体層などの材料層に高アスペクト比の開口部を形成している。典型的なプラズマ支援エッチング処理では、処理チャンバ内でプラズマを形成し、プラズマからのイオンを、基板とその上のマスクに形成された開口部とに向けて加速させて、マスク表面の下の材料層に開口部を形成する。通常は、400kHzから2MHzの範囲の低周波RF電力を基板に結合させることにより、イオンは基板に向かって加速され、これにより、そこにバイアス電圧が発生する。しかしながら、RF電力を基板に結合すると、基板にはプラズマに対する単一の電圧が印加されない。一般的に用いられる構成では、基板とプラズマの間の電位差は、ゼロに近い値から最大となる負の値までRF電力の周波数で振動する。プラズマから基板へイオンを加速させている電位が単一でないことにより、基板表面及びその材料層に形成される開口部(フィーチャー)では広範囲のイオンエネルギーがもたらされる。加えて、RFバイアスに起因するイオン軌跡の相違により、基板表面に対するイオンの角度分布は大きくなる。アスペクト比の高いフィーチャーの開口部をエッチングする場合、イオンエネルギーの範囲が広いことは望ましくない。それは、イオンが、望ましいエッチング速度を維持するのに十分な高エネルギーを有してフィーチャーの底部にまで到達しないからである。基板表面に対するイオンの角度分布が大きいことも望ましくない。それは、大きな角度分布は、フィーチャープロファイルの変形(その垂直側壁のくびれや曲がりなど)を引き起こすからである。
