Patent ID: 8079375

Claim:
A processing apparatus configured to process a substrate under a vacuum environment, the processing apparatus comprising: a processing chamber for processing the substrate; a load lock chamber connected to the processing chamber via a gate valve; a holding unit arranged in the load lock chamber and configured to hold a back surface side of the substrate; a dust collection part having a surface opposite to a front surface of the substrate held by the holding unit; a temperature controlling unit configured to control a temperature of the surface of the dust collection part opposite to the front surface of the substrate to a temperature lower than a temperature of the substrate; a driving unit configured to bring one of the holding unit and the dust collection part close to the other of the holding unit and the dust collection part; and a driving controller configured to control the driving unit moving at least one of the holding unit and the dust collection part, where the temperature has been controlled, closer to the other so that a distance between the front surface of the substrate and the surface of the dust collection part after importing the substrate into the load lock chamber becomes smaller than the distance during the importation.
