Abstract: An apparatus for processing a workpiece, such as a semiconductor wafer, includes a rotor for holding workpieces within a process chamber. A gas pressure seal around the shaft of the rotor has a shaft adapter on the shaft and an o-ring providing a seal between the shaft and the shaft adapter.
