図1に示した半導体処理装置を用いて、シリコン基板上に成膜した厚さ100nmのHfO2膜のエッチングを行った。プラズマを発生させるには、2.45GHzのマイクロ波と875Gの磁界を用いた。載置電極には、高周波電源から電力を供給せずに、シリコン基板をプラズマに暴露した。エッチングガスにはBCl3とO2との混合ガスを用い、O2の添加量を、0%、10%、20%と変化させた。エッチングの条件を表1に示す。プラズマ暴露前後のHfO2膜の膜厚の差を段差計で測定し、エッチング速度を求めた。混合ガス中の酸素添加量を変化させた時のHfO2膜のエッチング速度との関係を図2のグラフに示す。
混合ガス中の酸素添加量を0%または10%とし、チャンバー内の真空度を5、6、8、10、12mTorrと変化させた以外は、実験例1と同様にしてエッチングを行い、HfO2膜の膜厚の差を測定し、エッチング速度を求めた。エッチングの条件を表2に示す。混合ガス中の酸素添加量及び真空度を変化させた時のHfO2膜のエッチング速度との関係を図3のグラフに示す。
混合ガス中の酸素添加量を10%とし、チャンバー内の真空度を5、10、12mTorrに変化させた以外は、実験例2と同様にしてエッチングを行い、HfO2膜とシリコン基板の膜厚の差を測定し、エッチング速度を求めた。混合ガス中の真空度を変化させた時のHfO2膜及びシリコン基板のエッチング速度との関係を図4のグラフに示す。
