Abstract
A field-effect transistor. The field-effect transistor includes: a source layer doped according to a first type, a drain layer doped according to a first type, a channel layer located vertically between the source layer doped according to the first type and the drain layer doped according to the first type, and a gate trench which extends vertically from the source layer doped according to the first type to the drift layer doped according to the first type and adjoins the channel layer. The channel layer has, at least on average, a lower doping of the second type and a higher doping of the first type in a region that is more than a specified distance from the gate trench than in a region that is less than the specified distance from the gate trench. Methods for production are also described.
