  • Patent number: 7238092
    Abstract: The present invention relates to semiconductor integrated circuit technology and discloses an electrochemical mechanical processing system for uniformly distributing an applied force to a workpiece surface. The system includes a workpiece carrier for positioning or holding the workpiece surface and a workpiece-surface-influencing-device (WSID). The WSID is used to uniformly distribute the applied force to the workpiece surface and includes various layers that are used to process and apply a uniform and global force to the workpiece surface.

  • Patent number: 6530397
    Abstract: A multi-channel rotary joint including a first joint structural member rotatably linked to a second joint structural member. Sealing regions defined and formed by mechanical seals that are lined up concentrically around relative rotational axis are provided between opposing peripheral surfaces in a relative rotational axial direction of the first and second joint structural members. A plurality of channels passing independently through the sealing regions (except for the sealing region which is used as a drain region) are provided for the first and second joint structural members, and an electrical wire insertion path is provided so as to pass through the inner peripheral region of a mechanical seal that has the smallest diameter. A drain path that opens into the drain region is provided for the joint structural member.

  • Patent number: 6120357
    Abstract: Systems and methods of thermal control in the carbon dioxide cleaning of data storage disks to reduce or prevent condensation on the surface of the media during cleaning with frozen carbon dioxide are disclosed. A hub recess receives at least a portion of the outer flange of the hub to improve contact between the data storage media and a media platform supporting the media. Contact between the media and the media platform may be further improved by drawing a vacuum through openings in the media platform. In addition, drawing a vacuum through a vacuum channel with an annular ring opening about the media platform and a tangential vacuum port may reduce fluttering of the media on the media platform.

  • Patent number: 5807162
    Abstract: A grinding apparatus comprises a table having a first bearing surface; a chuck mounted on the table for rotation about a chuck axis and provided with means for holding a workpiece, the chuck having on its underside a second bearing surface, such that when the chuck is stationary, the second bearing surface rests on the first bearing surface; a grinding head having a least one grinding surface capable of grinding a workpiece mounted on the table, the grinding head being mounted for rotation about a head axis substantially parallel to the chuck axis; and transport means for moving the chuck relative to the grinding head in both directions along a transport axis substantially perpendicular to both the chuck axis and the head axis.
