    摘要: Substrate handling apparatus and methods are described. In one aspect, the substrate handling apparatus includes a clamping member having an extended condition wherein substrate movement relative to the transfer arm is substantially restricted and a retracted condition wherein substrate movement relative to the transfer arm is substantially free. The substrate handling apparatus further includes a sense mechanism (e.g., a vacuum sensor) constructed to determine whether a substrate is properly positioned on the support arm and to trigger the mode of operation of the clamping member between extended and retracted conditions. The sense mechanism also provides information relating to the operating condition of the clamping member.

    摘要: A carrier head for a chemical mechanical polishing system includes a substrate sensing mechanism. The carrier head includes a base and a flexible member connected to the base to define a chamber. A lower surface of the flexible member provides a substrate receiving surface. The substrate sensing mechanism includes a sensor to measure a pressure in the chamber and generate an output signal representative thereof, and a processor configured to indicate whether the substrate is attached to the substrate receiving surface in response to the output signal.
