Publication number: 20150318200Abstract: A wedge-shaped jig (6) is inserted into a gap between a first substrate (21) and a second substrate (22) at a corner (221) of the second substrate (22) and separation of the attached first substrate (21) and second substrate (22) starts to proceed; then, a second suction pad (53) of a second suction portion (51), which is the closest to the corner (221), moves upward. 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. Although the second substrate (22) warps as the separation of the second substrate (22) proceeds, each of the plurality of first suction pads (43) elastically deforms. 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.Type: ApplicationFiled: April 29, 2015Publication date: November 5, 2015Inventors: Masakatsu OHNO, Satoru IDOJIRI, Kanpei KIKUCHI, Yoshiharu HIRAKATA, Kohei YOKOYAMA

Publication number: 20150314424Abstract: 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.
