Abstract: In this letter,the physical model of insulated gate bipolar transistor(IGBT)was discussed firstly.Several important parameters that affect the performance of IGBT were analyzed,in order to provide theoretical support for the optimization and improvement of IGBT structural design.Moreover,the development of IGBT structural design and creative improvements made by different mainstream designers from the appearance of IGBT were mainly discussed.Furthermore,a new attractive research point,reverse conducting IGBT semiconductor device was introduced to explore the prospect of IGBT development.

Key words: IGBT, PT, NPT, SPT, Trench-FS, CSTBT, RC-IGBT
