Beschreibung
Zusammenfassung:	A plasma processing device in which plasma processing uniformity is improved up to an outer peripheral portion of a wafer and the number of non-defective devices that can be manufactured from one wafer is increased. The plasma processing device includes a vacuum container; a mounting table, a susceptor ring that covers an outer peripheral portion of an electrode base material, and an insulation ring covered by the susceptor ring and surrounding the electrode base material, and thin film electrode formed on an upper surface and a part of a surface facing the outer periphery of the electrode base material; a first high frequency power applied to the electrode base material a second high frequency power applied to the thin film electrode; a plasma generating unit that generates plasma on an upper portion of the mounting table inside the vacuum container; and a control unit.
