Abstract :
A trade-off between a low forward voltage and fast switching time is a very important characteristic for an insulated gate bipolar transistor (IGBT) that is used in applications such as inverters for motor control. A trench-IGBT has a very good trade-off but has a high cost because of the complicated structure. This study presents our new development of a 600 V planar-IGBT that has a trade-off characteristic comparable to that of a trench-IGBT. This has been realized by employing a device structure with a shallow p-base and shallow FLRs, and by using local lifetime control through He irradiation
