A Novel Low Power Loss IGBT (LPL-IGBT) and Its Simulation
低功耗IGBT(LPL-IGBT)及其仿真

A new structure IGBT,named Low Power Loss IGBT (LPL IGBT) is proposed.It keeps the advantages of NPT IGBTs because of its very thin and lightly doped p type back emitter formed using ion implantation.Meanwhile,it also takes the advantages of PT IGBTs due to its n type buffer layer which is the residual layer of the pre diffused n + region at the backside of the n - substrate.Simulation results show that its turn off power loss is almost a half of that of the PT IGBT or NPT IGBT.Furthermore,its structure is more suitable for practical production than FSIGBT.
