Abstract:
A plasma processing apparatus includes a baffle plate, a shutter, and a driving device. The baffle plate has a cylindrical shape, and has a plurality of through holes formed in a sidewall thereof. The shutter has a cylindrical shape and is provided around the baffle plate to be movable in an axial direction of the baffle plate along the sidewall of the baffle plate. The driving device moves the shutter along the sidewall of the baffle plate. The plurality of through holes are disposed in the sidewall of the baffle plate so that synthesized conductance of the through holes, which are not covered by the shutter, is increased with respect to a movement amount of the shutter as the shutter is moved downward.

Claim (Index 1):
A plasma processing apparatus that performs plasma processing on a workpiece, the plasma processing apparatus comprising:\n a processing container; a placement table provided in the processing container and configure to place the workpiece thereon; a cylindrical baffle plate having a plurality of through holes formed in a sidewall thereof, and defining a processing space above the placement table and a gas discharge space around the placement table; a cylindrical shutter having an inner circumferential surface having a diameter larger than a diameter of an outer circumferential surface of the baffle plate, is the shutter being provided around the baffle plate to be movable in an axial direction of the baffle plate along the sidewall of the baffle plate; and a driving device configured to change synthesized conductance made by the plurality of through holes, which are not covered by the shutter, by moving the shutter along the sidewall of the baffle plate, wherein the plurality of through holes are disposed in the sidewall of the baffle plate such that a change amount of the synthesized conductance of the through holes, which are not covered by the shutter, is increased with respect to a movement amount of the shutter as the shutter is moved downward.
