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 1):
A semiconductor component, comprising:\n a field effect transistor arrangement in a semiconductor body, the field effect transistor arrangement comprising a drift zone and a body region between the drift zone and a first surface of the semiconductor body; a plurality of trench structures of a first type comprising a first and a second trench structure, which 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 the first and second trench structures, wherein the first trench structure and the second trench structure are directly adjacent; and 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, wherein a net doping concentration is 10% greater at a first location in the drift zone than at a second location in the drift zone at a reference depth which is located between the body region and a bottom of the first trench structure, wherein the first location is at a same first lateral distance from the first and from the second trench structure, the second location is at a same second lateral distance from the first trench structure and from the second trench structure, wherein the second distance is greater than the first distance.
