Abstract
To realize low on-state voltage and high switching speed, a new device, a CIFET (Carrier Injection Field Effect Transistor), is proposed. The fabricated 350 V lateral CIFET has a low on-state voltage of less than 0.8 V at 100 A/cm2, which is difficult to be achieved by IGBTs, ESTs and MCTs. Its fall time is reduced to about 0.2 μs by electron irradiation. Early removal of the injected gate current (more than 5 μs) before removing the MOS gate voltage shortens the fall time to about 70 ns
