摘要
A semiconductor device includes a first conductivity-type drift region including an exposed portion, a plurality of second conductivity-type body regions, a first conductivity-type source region, a gate portion and a Schottky electrode. The drift region is defined in a semiconductor layer, and the exposed portion exposes on a surface of the semiconductor layer. The body regions are disposed on opposite sides of the exposed portion. The source region is separated from the drift region by the body region. The gate portion is disposed to oppose the body region. The exposed portion is formed with a groove, and the Schottky electrode is disposed in the groove. The Schottky electrode has a Schottky contact with the exposed portion.
