Abstract:
Provided is a plasma processing apparatus which comprises a chamber, a stage configured to set a holding sheet and a substrate held thereon, a securing mechanism configured to secure the holding sheet on the stage, a plasma generator including a first electrode and a first high-frequency power supply, and a determiner for determining a contact status between the holding sheet and the stage, wherein a gas through-hole is arranged on a surface of the stage in an annular region defined between an inner edge of a frame set on the stage and an outer edge of the substrate, and wherein the determiner is configured to determine the contact status in accordance with a pressure of a gas in the gas introduction conduit and/or a regulation data for regulating the pressure of the gas, the gas being introduced between the stage and the holding sheet from the gas through-hole.

Claim (Index 4):
The plasma processing apparatus according to  claim 1 , further comprising:\n a bias-potential generator including a second electrode provided in the stage and a second high-frequency power supply for supplying a high-frequency power to the second electrode, wherein the second electrode has an outer edge arranged between the outer edge of the frame set on the stage and the outer edge of the substrate, and a second window arranged at a position corresponding to the gas through-hole.
