Claim:
1. Apparatus for holding a planar substrate, having a support that forms a supporting surface for the substrate, which has at least one supporting surface recess provided in the region of the supporting surface for the substrate, and having at least one holder connected with this supporting surface recess, in terms of flow, for fastening the substrate onto the apparatus, using a partial vacuum generated between the support and the substrate, wherein the support has at least one support recess having an elastic seal configured to be moveable from a position projecting beyond the edge of the support recess into a position agreeing with the edge support of the support recess, the elastic seal working together with the supporting surface recess to draw the substrate against the support over a full area of the substrate, by suction, wherein the elastic seal runs conically in cross-section, is free in a tilting direction, has two equal bending shanks in order to allow a tilting movement of the elastic seal, and is structured as a tubular seal.
