  • Patent number: 12684829
    Abstract: In a field effect transistor, trench lower layers are disposed directly below corresponding trenches. Deep layers of p-type extend along a first direction intersecting the trenches and are arranged at intervals along a second direction orthogonal to the first direction. A drain-side layer of n-type is distributed from a position in contact with a lower surface of a body layer to a position below a lower end of each of the deep layers through intervals between the deep layers. The drain-side layer includes a high concentration layer distributed in at least a part of a depth range in which both the deep layers and the trench lower layers are present, and an intermediate concentration layer distributed in at least a part of a depth range between a lower end of the high concentration layer and a lower end of each of the deep layers.
