Abstract :
A 2 μm rule DMOS/CMOS compatible IGBT (insulated-gate bipolar transistor) with high reverse blocking capability has been developed for multipoint differential line drivers. Remarkable improvement of the reverse blocking capability and large latch-up current are achieved due to the formation of the wide N-base, the heavily doped N-buffer, and the P-well around the P-base. The effect of the conductivity modulation, arising from the injected holes, is compared with the DMOSFET in series with a P-ν-N diode
