Abstract
There is provided a method of performing a surface treatment with respect to a metal mounting table for mounting a substrate to be plasma-processed, the mounting table functioning as a lower electrode configured to generate a plasma by a high frequency power applied between an upper electrode and the lower electrode. The method includes: performing a first surface treatment by spraying a non-sublimation blast material as a non-sublimation material onto a mounting surface of the metal mounting table on which the substrate is mounted, followed by a second surface treatment by spraying a sublimation blast material as a sublimation material onto the mounting surface.
