In this paper, a new lateral insulated gate bipolar transistor (LIGBT) is proposed to improve the latch-up performance without current path underneath the n+ cathode region. The improvement of latch-up performance is verified using the two-dimensional simulator MEDICI and the simulation results on the latch-up current density are 3.12${\times}$10$\^$-4/ A/$\mu\textrm{m}$ for the proposed LIGBT and 0.94${\times}$10$\^$-4/ A/$\mu\textrm{m}$ for the conventional LIGBT. The proposed SOI LIGBT exhibits 3 times larger latch-up capability than the conventional SOI LIGBT.
