  • Patent number: 7513062
    Abstract: In a first aspect, a first method of drying a substrate is provided. The first method includes the steps of (1) lifting a substrate through an air/fluid interface at a first rate; (2) directing a drying vapor at the air/fluid interface during lifting of the substrate; and (3) while a portion of the substrate remains in the air/fluid interface, reducing a rate at which a remainder of the substrate is lifted through the air/fluid interface to a second rate. The drying vapor may form an angle of about 23° with the air/fluid interface and/or the second rate may be about 2.5 mm/sec.

  • Publication number: 20070004316
    Abstract: An integrated process tool for chemical mechanical processing, cleaning and drying a semiconductor workpiece is provided. The integrated process tool includes a CMP module and a cleaning and drying module. After being processed, the workpiece is transported from the CMP module to the cleaning and drying module using a movable housing. In the cleaning and drying module, a cleaning mechanism is used to clean the workpiece while the workpiece is rotated and held by a support stucture of the movable housing. A drying mechanism of the cleaning and drying module picks up the workpiece from the moveable housing and spin dries it. Throughout the CMP process, cleaning and drying, the processed surface of the wafer faces down.

  • Patent number: 6454332
    Abstract: 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.
