Abstract: A substrate processing apparatus is provided. The apparatus comprises a chamber; a substrate support which is arranged in the chamber and has at least one first gas supply path; and at least one control valve configured to control a flow rate or pressure of gas supplied through the at least one first gas supply path. The substrate support includes a base, and an electrostatic chuck which is arranged on the base and has an upper surface. The upper surface has a plurality of protrusions and a first annular groove group. The first annular groove group comprises a first inner annular groove, a first intermediate annular groove, and a first outer annular groove. Any one of the first inner annular groove, the first intermediate annular groove, and the first outer annular groove communicates with the at least one first gas supply path.

Abstract: A vehicle seat assembly apparatus includes: a base part; a cushion working part which is joined to one side of the base part and with which a seat cushion having a plurality of first through-holes formed therein can be placed and a seat cover can be joined to the seat cushion; and a cover working part which is joined to the other side of the base part and with which the seat cover can be placed and the seat cover can be moved to an upper part of the seat cushion. The cover working part makes it possible to align the angles of clips to be joined to suspenders of the seat cover.

Abstract: A placement stage includes: a wafer placement part having a placement surface and a first through hole; a base bonded to a rear surface of the wafer placement part by a first adhesive layer, and including a second through hole formed in the base, the second through hole communicating with the first through hole; a sleeve installed in the second through hole to be detachable from the base; and the sealing member installed between the rear surface and the sleeve to be spaced apart from the first adhesive layer so as to seal the first adhesive layer. A convex portion is formed to extend on an outer circumference or an inner circumference of a tip end of the sleeve, and the sealing member is pressed against a tip end surface of the sleeve to expand and contract.
