摘要: PROBLEM TO BE SOLVED: To provide a semiconductor device for power which has a high break down voltage property and a short tune-on time and can be operated at high speeds and has a small switching loss. SOLUTION: In a power MOSFET, having a p+-type embedded layer 9 in an n--type drift layer 1, a p+-type carrier injection layer 10 connected to a second gate electrode 11 is formed at the side of a p-type base layer 4 to inject holes into the n--type drift layer 1 from the p+-type carrier injection layer 10 at turning on. By rapidly eliminating the depletion of the p+-type embedded layer 9 by injection holes from the p+-type carrier injection layer 10, the turn-on time can be shortened and a high speed operation is made possible, and additionally, switching loss is made small.
