Original Abstract Submitted
In order to execute stable processing by suppressing plasma diffusion and non-stationary discharge generation, there is provided a plasma processing device which includes a processing chamber in which a sample stage is provided for placing a sample thereon, an exhaust unit for evacuating the processing chamber, a magnetic field forming mechanism for forming a magnetic field in the processing chamber, and a power supply unit that supplies radio frequency power for generating plasma to the inside of the processing chamber evacuated by the exhaust unit and has the magnetic field formed by the magnetic field forming mechanism. The processing chamber includes a shielding section which divides an inner part of the processing chamber into a first area at a side for supplying the radio frequency power from the power supply unit and a second area at a side where the sample stage is disposed. The shielding section includes a first shielding plate disposed at the side that faces the first area, in which a first opening is formed, a second shielding plate disposed at the side that faces the second area, in which a second opening is formed at the center, and a third shielding plate disposed between the first and the second shielding plates.
