摘要:
In one embodiment, a semiconductor device comprises a semiconductor material having a first conductivity type with a body region of a second conductivity type disposed in the semiconductor material. The body region is adjacent a JFET region. A source region of the first conductivity type is disposed in the body region. A gate layer is disposed over the semiconductor material and has a first opening over the JFET region and a second opening over the body region.
