Abstract :
A novel bulk junction isolated lateral insulated gate bipolar transistor (JI-LIGBT) with a heavily doped buried-layer in substrate is presented. Due to electric field modulation and current-gain reduction of the vertical parasitic transistor from the buried-layer, in comparison with the conventional LIGBT without a buried-layer, the novel structure offers not only high breakdown voltage but also short turn-off time and significantly low substrate leakage current.
