Abstract
A new semiconductor power device, suitable for electrical switching in automotive applications, is proposed. This device combines the low specific on-resistance achievable with bipolar regenerative switching devices with the convenience of insulated gate control of not only turn-on but also turn-off. A device structure is presented that also includes a pinch resistance effect to more rapidly produce turn-off.
