Abstract
Die Erfindung betrifft eine Haltevorrichtung (100), insbesondere Chuck, für ein Substrat (101), mit einem Grundkörper (103) mit einer Oberseite (105), einem Trägerelement (107), wobei das Trägerelement (107) in einer Aussparung (109) des Grundkörpers (103) so vertikal bewegbar angeordnet ist, dass es zwischen einer vorstehenden Beladestellung und einer zurückgezogenen Spannstellung verstellbar ist, und wobei das Trägerelement (107) eine Auflagefläche (111) zum Auflegen des Substrats (101) umfasst, wobei die Auflagefläche (111) einen geringeren Durchmesser als der Grundkörper (103) aufweist, und einem Hebeelement, welches das Trägerelement (107) in die Beladestellung anhebt, wobei das Trägerelement (107) die Aussparung (109) so abdichtet, dass zwischen dem Grundkörpers (103) und dem Trägerelement (107) ein abgedichteter Hohlraum (113) vorliegt, welcher mit einem Unterdruck beaufschlagbar ist, der der Wirkung des Hebeelements entgegenwirkt, und wobei Abstandshalter (117a, 117b) vorgesehen sind, die die Spannstellung des Trägerelements (107) definieren, in der die Auflagefläche (111) des Trägerelements (107) im Wesentlichen bündig mit der Oberseite (105) des Grundkörpers (103) angeordnet ist.
