Patent ID: 8426323

Claim:
A substrate processing apparatus comprising: a chamber capable of being evacuated; a substrate stage adapted to, in the chamber, mount a substrate; a heating unit adapted to, in the chamber, be set above a substrate mounting surface of the substrate stage, face the substrate mounted on at least the substrate mounting surface, and heat the substrate by radiant heat without being in contact with the substrate; a shutter adapted to, in the chamber, be retractably inserted in a space between the heating unit and the substrate mounted on the substrate mounting surface; and a shutter driving unit adapted to, in the chamber, extend/retract the shutter into/from the space, wherein the shutter has a first principal surface serving as a heat reflecting surface, and a second principal surface serving as a heat absorbing surface, wherein the shutter is disposed such that said first principal surface faces the heating unit and said second principal surface faces the substrate stage when the shutter extends into the space, and wherein the shutter includes a first cooling unit adapted to have an outer periphery surrounded by a sealing member.
