Abstract:
A semiconductor component includes a field-effect transistor arrangement having a drift zone and body region between the drift zone and a first surface of a semiconductor body. Trench structures of a first type extend from the first surface into the semiconductor body and have a maximum lateral dimension at the first surface which is less than a depth of first and second ones of the trench structures. A net doping concentration at a reference depth at a first location in the drift zone is at least 10% greater than at a second location in the drift zone at the reference depth, which is located between the body region and a bottom of the first trench structure. The first location is at the same first lateral distance from the first and second trench structures. The second location is at the same second lateral distance from the first and second trench structures.

Claim (Index 15):
A method for producing a semiconductor component, the method comprising:\n forming a field effect transistor arrangement in a semiconductor body, comprising: forming a plurality of trenches of a first type comprising a first and a second trench, which extend from a first surface into the semiconductor body and have a maximum lateral dimension at the first surface which is less than a depth of the first and second trenches, wherein the first trench and the second trench are directly adjacent; forming at least one trench structure of a second type which comprises a gate electrode and a gate dielectric and extends from the first surface into the semiconductor body less deeply than the plurality of trench structures of the first type; and setting a net doping concentration in a drift zone at a first location, which is at a same first lateral distance from the first trench and from the second trench, to be at least 10% greater than at a second location, which is at a same second lateral distance from the first trench and from the second trench, wherein the second distance is greater than the first distance and the first location and also the second location are located at a reference depth between the first surface and a bottom of the first trench.
