Abstract: A novel trench field stop (TFS) IGBT with a super junction (SJ) floating layer (SJ TFS-IGBT) is proposed. This IGBT presents a high blocking voltage (> 1200 V), low on-state voltage drop and fast turn-off capability. A SJ floating layer with a high doping concentration introduces a new electric field peak at the anode side and optimizes carrier distribution, which will improve the breakdown voltage in the off-state and decrease the energy loss in the on-state/switching state for the SJ TFS-IGBT. A low on-state voltage (VF) and a high breakdown voltage (BV) can be achieved by increasing the thickness of the SJ floating layer under the condition of exact charge balance. A low turn-off loss can be achieved by decreasing the concentration of the P-anode. Simulation results show that the BV is enhanced by 100 V, VF is decreased by 0.33 V (at 100 A/cm2) and the turn-off time is shortened by 60%, compared with conventional TFS-IGBTs.

Key words: IGBT,  Super Junction (SJ),  on-state voltage,  breakdown voltage,  energy loss,  charge balance
