Abstract: Embodiments of the invention contemplate a shadow ring that provides increased or decreased and more uniform deposition on the edge of a wafer. By removing material from the top and/or bottom surfaces of the shadow ring, increased edge deposition and bevel coverage can be realized. In one embodiment, the material on the bottom surface is reduced by providing a recessed slot on the bottom surface. By increasing the amount of material of the shadow ring, the edge deposition and bevel coverage is reduced. Another approach to adjusting the deposition at the edge of the wafer includes increasing or decreasing the inner diameter of the shadow ring. The material forming the shadow ring may also be varied to change the amount of deposition at the edge of the wafer.

Abstract: A method and apparatus for processing a substrate are provided. The apparatus includes a pedestal and rotation member, both of which are moveably disposed within a processing chamber. The rotation member is adapted to rotate a substrate disposed in the chamber. The substrate may be supported by an edge ring during processing. The edge ring may selectively engage either the pedestal or the rotation member. In one embodiment, the edge ring engages the pedestal during a deposition process and the edge ring engages the rotation member during rotation of the substrate. The rotation of the substrate during processing may be discrete or continuous.
