Abstract:
To improve processing uniformity by improving a working characteristic in an edge exclusion region. Provided is a plasma processing apparatus for processing a sample by generating plasma in a vacuum vessel to which a processing gas is supplied and that is exhausted to a predetermined pressure and by applying a radio frequency bias to a sample placed in the vacuum vessel, wherein a conductive radio frequency ring to which a radio frequency bias power is applied is arranged in a stepped part formed outside a convex part of the sample stage on which the wafer is mounted, and a dielectric cover ring is provided in the stepped part, covering the radio frequency ring, the cover ring substantially blocks penetration of the radio frequency power to the plasma from the radio frequency ring, and the radio frequency ring top surface is set higher than a wafer top surface.

Claim (Index 18):
The plasma processing method according to  claim 15 , wherein\n the thickness of a portion of the dielectric ring member disposed above the ring-shaped member and covers the same is in a range of 1.0 mm to 5.0 mm.
