A lateral insulated gate bipolar transistor comprises a substrate (10); an anode terminal located on the substrate, comprising: an N-type buffer region (51) located on the substrate (10); a P well (53) located in the N-type buffer region; an N-region (55) located in the P well (53); two P+ shallow junctions (57) located on a surface of the P well (53); and an N+ shallow junction (59) located between the two P+ shallow junctions (57); a cathode terminal located on the substrate; a draft region (30) between the anode terminal and cathode terminal; and a gate (62) between the anode terminal and cathode terminal.
