Abstract:
1. A device for layered deposition of various materials on a semiconductor substrate, comprising a processing space with a substrate support disposed therein, on which the semiconductor substrate can be placed, one or more inlets for supplying the various materials in gaseous form to the processing space, as well as a lift pin which can be moved into and out of the plane of the substrate support to assist in introducing the semiconductor substrate into the processing space and removing it therefrom, wherein the lift pin comprises a contact surface that is to be brought into contact with the semiconductor substrate and/or the substrate support, the contact surface being a surface of a glassy carbon layer, the lift pin also comprising silicon carbide underlying the glassy carbon layer, the glassy carbon layer being preventing the silicon carbide from contacting the semiconductor substrate and/or the substrate support; wherein the glassy carbon layer has a lower hardness than the substrate support.
