  • Publication number: 20140093336
    Abstract: In the substrate holder, while holding a periphery portion of a semiconductor wafer, some of protruding portions having a grass shape on a pad main body hide beneath the semiconductor wafer, and the others of the protruding portions are exposed outside the semiconductor wafer. Also, the protruding portions hiding beneath the semiconductor wafer contact a rear surface of the semiconductor wafer, and sink the semiconductor wafer to a suitable depth via gravity, thereby holding the semiconductor wafer mainly in a length direction. In addition, some of protruding portions exposed near the periphery portion of the semiconductor wafer contact a side surface of the semiconductor wafer, thereby holding the semiconductor wafer mainly in a width direction.

  • Publication number: 20120087766
    Abstract: There is provided a transfer module capable of enhancing strength of a transfer chamber. An openable/closable cover is provided at the transfer chamber configured to be evacuable to vacuum. A robot is provided in the transfer chamber. The robot has hollow rotation shafts at a part of a device for transferring a processing target object W. A pillar for supporting the cover in a closed state is positioned within the hollow rotation shafts of the robot. Since the pillar supports a load applied to the cover by an atmospheric pressure, a thickness of the cover can be reduced, so that manufacturing cost can be reduced. Further, the robot is not interfered by the pillar when the robot rotates the processing target object W about the rotation shafts or moves the processing target object W in a radial direction.

  • Patent number: 7857569
    Abstract: A supporting mechanism (12A) is used for transfer-ring a target substrate (W) in cooperation with a transfer arm (32), in a semiconductor processing system. The supporting mechanism includes first and second holding portions (38A to 38C, 40A to 40C) each configured to be moved up and down and transfer a substrate to and from the transfer arm. The first and second holding portions are configured to be moved relative to each other in a vertical direction without spatially interfering with each other, and support substrates at substantially the same horizontal coordinate position. The supporting mechanism further includes first and second drives (46, 48) configured to move the first and second holding portions up and down, and a controller (68) configured to control the first and second drives. The controller is arranged to control the first and second drives to alternatively support a substrate by the first and second holding portions.
