초록

In this paper, a new silicon-on-insulator (SOI) 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 4468 A/cm2 for the proposed LIGBT and 1343 A/$\textrm{cm}^2$ for the conventional LIGBT. The proposed SOI LIGBT exhibits 3 times larger latch-up capability than the conventional SOI LIGBT.T.
