  • Patent number: 6315833
    Abstract: An apparatus for and method of supporting a substrate such as a semiconductor wafer. Silicon carbide sleeves cover substrate support members such as upwardly extending arms of a substrate carrier which is part of a substrate support assembly. The substrate carrier including the upwardly extending arms holds the substrate spaced apart from a platform such as a susceptor during loading and unloading of a processing chamber. The platform defines apertures through which the arms extend. The arms are vertically movable through the apertures with respect to the platform and engage the substrate at the substrate's edge or alternatively, inwardly from the edge.
