Abstract

See full text

An electrostatic chuck and gripping system are configured for clamping and processing workpieces having differing diameters. An ion implantation apparatus selectively provides ions to a first workpiece and a second workpiece in a process chamber, where a diameter of the first workpiece is greater the second workpiece. A chuck supports the respective first or second workpiece within the process chamber during exposure to the ions. A load lock chamber isolates a process environment from an external environment and has a workpiece support for the respective first or second workpiece during a transfer of the first or second workpiece between the process chamber and the external environment. A vacuum robot transfers the first or second workpiece between the chuck and workpiece support, and has a gripper mechanism configured to selectively grip the first or second workpiece between a plurality of stepped guides.
