Semiconductor device for switch-mode power supply, has terminal electrode connected to drift zone via channel that is conductive when control voltage is equal to zero

摘要

The device has a channel zone (5A,5B,5C) arranged between a connection zone (2) and a drift zone. A first channel (51) formed adjacent to a control electrode is conductive when the control voltage is not equal to zero. A first terminal electrode (22) is connected to the drift zone via at least one second channel (71) of a first conductivity type, conductive when a control voltage is equal to zero. An Independent claim is included for a method of manufacturing a semiconductor device.
