DEVICES, COMPONENTS AND METHODS COMBINING TRENCH FIELD PLATES WITH IMMOBILE ELECTROSTATIC CHARGE |
摘要 |
N-channel power semiconductor devices in which an insulated field plate is coupled to the drift region, and immobile electrostatic charge is also present at the interface between the drift region and the insulation around the field plate. The electrostatic charge permits OFF-state voltage drop to occur near the source region, in addition to the voltage drop which occurs near the drain region (due to the presence of the field plate). |
