Abstract
A semiconductor processing chamber includes a substrate support member on which the substrate is positioned during processing in the chamber. To align the substrate on the substrate support member, an alignment member extends about the perimeter of the substrate receiving portion of the support member. The alignment member includes an alignment face thereon, which urges a substrate into alignment with the substrate receiving face of the support member as the substrate is deposited on the support member. The alignment member may also include a recessed portion, which ensures the presence of a gap between the edge of the substrate and the support member when the substrate contacts the support member.
