A reverse-channel, high-voltage lateral IGBT

A novel reverse-channel lateral IGBT has been studied with numerical simulations and demonstrated experimentally for the first time. It exhibits a negative differential resistance (NDR) region, which is dependent on the gate voltage and has large peak to valley ratios (10 to >1000), in the I-V characteristics. Also, during dynamic switching, it has been shown to be self-current limiting and hence not to latch up.
