Static induction type semiconductor device










Image Number 7 for United States Patent #4998149.

Disclosed is an improvement of a static induction type semiconductor device which includes an anode region provided at one surface portion of a semiconductor substrate, a cathode region provided on the other surface portion, a gate region adjacent to the cathode region and a low impurity density region formed at an intermediate portion of the semiconductor substrate. A cathode short region is provided at a position opposite to the cathode region with the gate region therebetween so as to be conducted to the cathode region, thereby quickening the injection of charge at the time of turn-on and draw up of charge at the time of turn-off, and enabling high-speed on and off operation.
