Abstract:
A semiconductor body having a drift region layer, a body region layer adjoining the drift region layer, and a source region layer adjoining the body region layer and forming a first surface of the semiconductor body is provided. At least two trenches extend from the first surface of the semiconductor body through the source region layer and the body region layer. In each of the trenches a gate electrode and a gate dielectric are formed. Diode regions are directly adjacent to each of the at least two trenches. The diode regions extend from the first surface of the semiconductor body through the source region layer and the body region layer. The diode regions include a first region and a second region. A doping concentration in the diode regions varies such that a doping concentration is higher near the first surface than at the bottom of the trench.

Claim (Index 3):
The method of  claim 2 , wherein forming the diode regions comprises:\n forming an implantation mask on the first surface of the semiconductor body, the implantation mask comprising openings that expose a portion of the first surface; performing a first implantation step comprising implanting dopant atoms through the openings in the implantation mask; and performing a second implantation step after performing the first implantation step, the second implantation step comprising implanting dopant atoms through the openings in the implantation mask, wherein the first implantation step forms the first region of the diode regions, and wherein the second implantation step forms the second region of the diode regions.
