Abstract: A film-like member is supported in a flat shape by vacuum suction. A plurality of lift pins are arranged in a planar configuration and bear a film-like member placed on their upper ends. Tubular pads made of rubber for holding the film-like member by vacuum suction are attached to upper portions of the lift pins. The height of the lift pins can be adjusted by a screw fastening mechanism. The deformation of the film-like member can be corrected to a flat or concavely curved shape by suction from the pads. When the correction cannot be achieved by suction alone, the correction may be supplemented by ejection of air from a nozzle.

Then, first suction pads (43) of first suction portions (41a), (41b), and (41c) sequentially move upward such that one side of the second substrate (22) separates from the stacked body.

Therefore, the first suction pads (43) can be prevented from being detached from the second substrate (22), and the substrate (22) can be securely separated from the stacked body.
