摘要: Provided is a method of selectively removing first region from workpiece which includes the formed silicon oxide and second silicon. The performs plurality sequences. Each sequence includes: forming denatured by generating plasma processing gas that contains hydrogen, nitrogen, fluorine within container accommodates so as to denature portion region, container. In addition, subsequent predetermined number sequences after among further exposing reducing generated container, prior region.
