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 9):
A semiconductor device, comprising:\n a semiconductor body comprising 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; at least two trenches each extending from the first surface of the semiconductor body through the source region layer and the body region layer such that a bottom of the at least two trenches reaches the drift region layer; a gate electrode and a gate dielectric formed in each of the at least two trenches, the gate dielectric dielectrically insulating the gate electrode from the semiconductor body, diode regions directly adjacent to each of the at least two trenches, each of the diode regions extending from the first surface of the semiconductor body through the source region layer and the body region layer such that a bottom of each of the diode regions reaches the drift region layer, wherein the diode regions each comprise a first region and a second region, wherein a doping concentration in each of the diode regions varies along an extension direction of the diode regions such that a doping concentration is higher near the first surface than at the bottom of the trench.
