The plasma processing apparatus is provided with a plasma source 13 which generates plasma inside a chamber 11, a stage 16 which is provided inside the chamber 11 and places a carrier 5 thereon, a cover 31 which is arranged above the stage 16 to cover a holding sheet 6 and a frame 7 and has a window 33 which is formed to penetrate the cover 31 in the thickness direction, and a drive mechanism 38 which changes the position of the cover 31 relative to the stage 16 between a first position and a second position. The second position does not allow the cover 31 to make contact with the holding sheet 6, the frame 7 and a substrate 2. The cover 31 includes at least a ceiling surface 36b which extends in parallel to the upper face of the frame 7 and an inclined surface 36c which is inclined to gradually come close to the upper face of the holding sheet 6 exposed at the inner diameter side of the frame 7. |
