| 摘要 |
A plasma processing apparatus includes a vacuum evacuable processing chamber; a first electrode for mounting thereon a substrate to be processed in the processing chamber; a second electrode facing the first electrode in parallel in the processing chamber; and a processing gas supply unit for supplying a processing gas to a processing space between the first and the second electrode. The apparatus further includes a first high frequency power supply for applying a first high frequency power for generating a plasma of the processing gas to at least one of the first and the second electrode; and a cavity plasma generation unit, having a cavity formed in one of the first and the second electrode, for generating a plasma of a discharging gas in the cavity. |
