Abstract:
A method for contacting a semiconductor configuration, the method which comprises:providing at least one p-conducting semiconductor region formed of silicon carbide; and applying a material having nickel as a first material component and aluminum as a second material component on the at least one p-conducting semiconductor region for forming at least one substantially homogeneous p-type contact region on the at least one p-conducting semiconductor region, by simultaneously applying both, the first material component and the second material component such that a given mixture ratio of the first material component and the second material component is established at an interface between the at least one p-conducting semiconductor region and the at least one p-type contact region prior to a heat-treatment process, the aluminum contained in the material having a proportion by volume of from 0.1% to 50% in the material.
