  • Seal for wafer processing assembly
    Patent number: 10269595
    Abstract: A seal having a cross-sectional profile that includes a first lobe, a second lobe, and a corner having an angle between 45 and 90 degrees, inclusive, a first side extending from the first lobe to the corner and a second side extending from the second lobe to the corner, where the first side and the second side define the corner angle. The seal can be seated in a groove so that the first lobe and the corner are in the groove and the second lobe extends from the groove. In use, the second lobe folds into the groove to form a fluid-tight seal.
    Type: Grant

  • WAFER HANDLING ASSEMBLY
    Publication number: 20170256436
    Abstract: A wafer handing assembly comprising a center hub supporting a vertical non-contact lifting head and at least one radially extending and radially retracting wafer engaging mechanism having a surface to engage a wafer at a peripheral edge of the wafer, where the peripheral edge is a corner edge or a side edge. In some implementations, the wafer engaging mechanism has a foot on which the wafer edge is supported.
