Patent ID: 7767054

Claim:
A plasma processing apparatus comprising: a vacuum processing chamber; supplying means for introducing a processing gas into the vacuum processing chamber; a mounting electrode in the vacuum processing chamber for mounting a specimen on the mounting electrode; a focus ring; and a pusher pin for raising the specimen placed on the mounting electrode and holding the specimen over the mounting electrode; wherein the mounting electrode is divided into an inner area for mounting the specimen, and an outer area for mounting the focus ring, the inner area and the outer area of the mounting electrode being electrically insulated from one another; wherein a high-frequency power source is provided for supplying electric power to the inner area and the outer area; wherein high-frequency electric power is applied to the outer area of the mounting electrode to generate plasma at the outer edge of the backside of the specimen while the specimen is raised with the pusher pin; and wherein a focus-ring-mounting face of the outer area is provided with a passage for discharging a coolant of the focus ring from the inner edge side of the focus ring to the inner area for mounting the specimen.
