Patent ID: 7537673

Claim:
A plasma processing apparatus for performing a predetermined process on a substrate using plasma, comprising: a chamber; a substrate mounting table equipped within the chamber to place the substrate thereon; an outer lifting bar provided at an outer side of the substrate mounting table to move up and down, and serving to temporarily support the substrate above the substrate mounting table, a baffle provided to shield a space formed between the substrate mounting table and a side wall of the chamber, and having a plurality of through holes formed on a predetermined portion of the baffle, the outer lifting bar comprising, a driving shaft moving up and down, a substrate supporting member coupled perpendicular to an upper end of the driving shaft the substrate supporting member being disposed above the substrate mounting table by pivoting the substrate supporting member about the driving shaft to a position above the substrate mounting table, shielding portion coupled to a side wall of the substrate mounting table, the shielding portion being opened at an upper surface to allow the substrate supporting member to move through the upper surface and be received in the shield portion, wherein the baffle and the substrate supporting member are driven vertically at the same time by the driving shaft.
