Abstract :
A new type of IGBT structure, with a trench gate placed in the middle of the JFET region, has been proposed. The device, called the trench-planar IGBT (TPIGBT) has been analysed in detail in terms of its on-state performance and resistive turn-off, and compared to a reference 2 kV planar, fine-lithography IGBT. Simulation results demonstrate that even the use of shallow trench of 3 μm can result in a low on-state voltage drop. Furthermore, the increased concentration of mobile charges, as a result of enhanced electron injection achieved through hole pile-up, can result in an increase in the turn-off time
