SEMICONDUCTOR DEVICE INCLUDING DIODE

摘要

PROBLEM TO BE SOLVED: To improve trade-off between a reverse recovery behavior and an on-state characteristic of a diode in a semiconductor device including the diode.

SOLUTION: A semiconductor device 200 includes a cathode 216 and an anode 218. The anode includes a first p-type semiconductor anode region 204 and a second p-type semiconductor anode region 206. The first p-type semiconductor anode region 204 is electrically connected to an anode contact area 218. The second p-type semiconductor anode region 206 is electrically coupled to the anode contact area 218 via a switch, such as a MOSFET 228, configured to provide an electrical connection or an electrical disconnection between the second p-type anode region and the anode contact area 218.
