Patent ID: 7322313

Claim:
A plasma processing apparatus for plasmatizing processing gas in an electric field and then blowing it out, said plasma processing apparatus comprising: a first and a second electrode opposed in a first direction and each extending in a second direction orthogonal to the first direction, each of said electrodes having a first and a second elongate side edge distant from each other in a third direction crossing both the first and the second directions, wherein: said electric field is applied between said first and second electrodes, an opening between said first elongate side edges serves as a processing gas receiving aperture, an opening between said second elongate side edges serves as a processing gas blowoff aperture, and said first electrode has a back surface opposite to said second electrode; a rigid member facing said back surface; and a pull screw extending in said first direction, wherein a head of said pull screw is hooked on said rigid member and a leg part of said pull screw is screwed in said first electrode through said back surface.
