Patent ID: 8337621

Claim:
A processing apparatus for processing a substrate, the processing apparatus comprising: a processing chamber for processing the substrate; a depressurizing mechanism reducing an internal pressure of the processing chamber; and a transfer mechanism disposed in the processing device chamber to convey the substrate, wherein the transfer mechanism comprises: a guide member; a stage for holding the substrate, the stage including a space isolated from an inner atmosphere of the processing chamber; a driving member for moving the stage; and a movable member supporting the stage and moving along the guide member, wherein the guide member and the movable member are maintained so as not to contact each other by a repulsive force of magnets, wherein a duct member is used for communication of the space with the outer atmosphere of the processing chamber and for restriction of at least one of an axial movement and a rotation of the stage, and wherein the driving member is cooled down by the outer atmoshere introduced through the duct member.
