Claim 0:
1. A vacuum processing apparatus which comprises a vacuum chamber and which performs a predetermined vacuum processing on a to-be-processed substrate set in position in the vacuum chamber, the vacuum chamber having therein a deposition preventive plate which is made up of a fixed deposition preventive plate and a moveable deposition preventive plate, the vacuum processing apparatus further comprising:
a block body which is made of metal, and which is located outside a circumference of the to-be-processed substrate, and disposed in a vertical posture on an inner wall surface of the vacuum chamber configured to cool the deposition preventive plate; and
a cooling means configured to cool the block body,
wherein the moveable deposition preventive plate is configured to move relative to the to-be-processed substrate between a processing position of the moveable deposition preventive plate at which processing position a predetermined vacuum processing is performed on the to-be-processed substrate, and a transporting position of the moveable deposition preventive plate at which the to-be-processed substrate can be transported, and
wherein, at a processing position, a clearance in a vertical direction between a top surface of the block body and the moveable deposition preventive plate is set to 1 mm or below or in contact with each other and, at the transporting position, the top surface of the block body is out of contact with the moveable deposition preventive plate.
