With a total of six patents to his name, Bartsch's work has advanced the capabilities of semiconductor devices.
Latest Patents
Among his latest patents is a method for processing a surface of an SiC semiconductor layer and Schottky contact. This innovative method involves treating the surface of an SiC semiconductor body produced by epitaxy. The process includes etching away parts of the epitactic layer deposited in the final phase of epitaxy, followed by a wet chemical treatment to eliminate a thin natural oxide on the surface. Additionally, a metal layer configured as a Schottky contact or an ohmic contact can be applied immediately after the removal process. Another significant patent is for a semiconductor device with an ohmic contact-connection and a method for establishing this connection. This device features an ohmic contact between an n-conducting silicon carbide semiconductor region and a largely homogeneous ohmic contact layer. The junction region contains a silicide and a carbide formed from the respective material components, which are created at a maximum temperature of 1000°C.
