Abstract

A new lateral insulated-gate bipolar transistor (LIGBT) structure on SOI substrate, called an n-region controlled anode LIGBT (NCA-LIGBT), is proposed and discussed. The n-region controlled anode concept results in fast switch speeds, efficient area usage and effective suppression NDR in forward I–V characteristics. Simulation results of the key parameters (n-region doping concentration, length, thickness and p-base doping concentration) show that the NCA-LIGBT has a good tradeoff between turn-off time and on-state voltage drop. The proposed LIGBT is a novel device for power ICs such as PDP scan driver ICs.
