Abstract:
1. A substrate processing device for processing a substrate comprising: at least one process chamber; processing tools arranged in the process chamber for processing the substrate; a substrate support having a frame and being received in the process chamber for supporting the substrate; and an edge exclusion projecting over a portion of the surface of the substrate for preventing processing of a portion of the substrate, wherein the edge exclusion is adapted to provide a labyrinth seal between an edge of the substrate and a frame element of the substrate support, wherein the labyrinth seal comprises at least a protrusion extending from a body portion of the edge exclusion, wherein the edge exclusion is movably arranged within the process chamber relative to the substrate support such that the protrusion is movable into a gap between the edge of the substrate and the frame element; at least a first fastening means fixedly attached to the frame for aligning the substrate relative to the frame by attaching the substrate to the first fastening means; and at least a second fastening means movably attached to the frame, the second fastening means being movable relative to the frame and/or movable relative to the substrate attached to the first fastening means.
