Abstract:
A vacuum processing apparatus according to this invention includes a heating unit arranged to face a processing surface of a substrate supported by a substrate support unit in a vacuum chamber, a cooling unit arranged to face a reverse surface of the substrate supported by the substrate support unit, a temperature correction unit configured to correct a temperature of a periphery of the substrate in order to reduce a temperature difference between a central portion and the periphery of the substrate by being arranged in a predetermined position between the substrate and the cooling unit when the heating unit heats the substrate, and a correction unit moving device configured to retract the temperature correction unit from the predetermined position.
