  • Patent number: 7789443
    Abstract: A gripper for use with a robot includes a support body for removably attaching the gripper to a moveable arm and a workpiece contact body having a groove extending along at least a portion of the contact body for engaging a curved outer edge of the workpiece. A coupling member connects the support body to the workpiece contact member and includes a flexure component that flexes to allow radial and/or tangential relative movement of the workpiece contact body with respect to the support body to diminish slippage between the workpiece and the contact body as the gripper engages the workpiece.
    Type: Grant
    Filed: March 16, 2007
    Date of Patent: September 7, 2010

  • Patent number: 6734439
    Abstract: The invention provides a wafer pad assembly for use in an ion implanter for mounting and cooling a wafer. The wafer pad assembly comprises a wafer support pad having an upper surface for mounting the wafer and a lower surface. The lower surface of the wafer support pad is connected to a coolant passage having an inlet section and an outlet section arranged in an opposed configuration, wherein said inlet section is counterbalanced by said outlet section. The lower surface is connected to a frame having an outer curved surface in mating engagement with a complementary shaped bearing surface of a housing wherein said wafer can be tilted or rotated about an axis.
