  • Reverse conducting IGBT
    Patent number: 10340373
    Abstract: The present invention relates to the technical field of the power semiconductor device relates to a reverse conducting insulated gate bipolar transistor (RC-IGBT). The RC-IGBT comprises a P-type region, an N-type emitter region, a P-type body contact region, a dielectric trench, a collector region, and an electrical filed cutting-off region. The beneficial effect of the present invention is that, when compared with traditional RC-IGBT, the IGBT of the present invention can eliminate negative resistance effect and effectively improve the performance of forward and reverse conduction.
