摘要:
A substrate holding apparatus in which first and second vacuum clamping devices each have a holding surface for holding a portion of a substrate, a first driving device for rotating the first vacuum clamping device relative to the second vacuum clamping device, and a second driving device for reciprocally moving the first vacuum clamping device between a position in which it protrudes by a predetermined amount from the holding surface of the second vacuum clamping device and a position in which it does not protrude from that holding surface. Also disclosed is a substrate holding device in which a vacuum clamping device creates a vacuum clamp force on the holding surface thereof, a cylindrical delivering member surrounds at least a portion of the holding surface and is reciprocally movable between a position in which it protrudes by a predetermined amount from the holding surface and a position in which it does not protrude from the holding surface, and a driving device for moving the delivering member.
