一种积累型沟道的半超结结构绝缘栅双极型晶体管

A high performance trench insulated gate bipolar transistor which combines a semi-superjunction struc- ture and an accumulation channel （sSJTAC-IGBT） is proposed for the first time. Compared with the TAC-IGBT, the new device not only retains the advantages of the accumulation channel, but also obtains a larger breakdown voltage （BV）, a faster turn-off speed and a smaller saturation current level while keeping the on-state voltage drop lower as the TAC-IGBT does as well. Therefore, the new structure enlarges the short circuit safe operating area （SCSOA） and reduces the energy loss during the turn-off process.
