Abstract
【解決手段】ウエハドライクリーニング装置10は、処理室11と、該処理室11内の下方に配置されてウエハWを載置する載置台12と、処理室11内において載置台12に対向配置された、パーティクルが付着した捕集板13と、誘導結合プラズマ生成装置であるプラズマ生成装置14とを備え、まず、処理室11内へダミーウエハ20を搬入し、該ダミーウエハ20の表面に正電位を発生させ、ダミーウエハ20よりも捕集板13の近傍での表面波プラズマの生成、及び表面波プラズマの生成の中止を交互に繰り返し、その後、処理室11内からダミーウエハ20を搬出する。
【選択図】図2
Description
前記異物吸着部材を、少なくとも前記消滅ステップにおいて正電位にすることを特徴とする。
パーティクル捕捉部28を用いることによってダミーウエハ20が吸着したパーティクルが再飛散するのを防止することができ、もって、処理室11内が再飛散したパーティクルによって再度汚染させるのを防止することができる。なお、このときも熱泳動力を大きく作用させるために、処理室11内の圧力を1.3×10Pa(100mTorr)〜1.3kPa(10Torr)に調整するのが好ましい。
