  • Semiconductor workpiece apparatus
    Patent number: 8323411
    Abstract: Various embodiments of an apparatus for holding and processing semiconductor workpieces are provided. In one aspect, an apparatus is provided that includes a first base, a second base and three elongated members coupled to and between the first base and the second base. The three elongated members are spatially arranged so that a semiconductor workpiece may be positioned therebetween. Each of the elongated members has a first lateral edge, a second lateral edge and at least one radially inwardly projecting member. The at least one radially inwardly projecting member has a third lateral edge, a fourth lateral edge and an upper surface for receiving a portion of the semiconductor workpiece and a lower surface. The third lateral edge is displaced laterally inward from the first lateral edge and the fourth lateral edge is displaced laterally inward from the second lateral edge.
    Type: Grant
