Abstract:
1. A semiconductor device, comprising: at least one ohmic contact region between a semiconductor substrate of the semiconductor device and an electrically conductive structure arranged adjacent to the semiconductor substrate; and at least one Schottky contact region between the semiconductor substrate of the semiconductor device and the electrically conductive structure, wherein the at least one ohmic contact region is arranged adjacent to the at least one Schottky contact region, wherein the semiconductor substrate comprises a first doping layer arranged adjacent to the electrically conductive structure, wherein an average doping concentration of a surface region of the first doping layer in an area of the at least one ohmic contact region differs from an average doping concentration of the surface region of the first doping layer in an area of the at least one Schottky contact region by less than 10% of the average doping concentration of the surface region of the first doping layer in the area of the at least one Schottky contact region.
