摘要

通过 TCAD 仿真系统地比较了 3300V 缩放绝缘栅双极晶体管 (IGBT) 在高温箝位感应关断下的稳健性，缩放因子 (k) 从 1 到 10 不等。在按比例缩放的 IGBT 中观察到了反向偏置安全工作区 (RBSOA) 的衰减，尤其是在高关断电流密度时。事实证明，非比例缩放方法能够恢复鲁棒性退化，其 RBSOA 接近原始的 k=1 情况。此外，Rpf（P-浮动连接电阻）调整方法为器件设计增加了更多灵活性，也提高了非比例缩放 IGBT 的整体电气性能。此外，Rpf 的调整对 RBSOA 的影响极小。

Robust reverse bias safe operating area (RBSOA) and improved electrical performance in 3300V non-proportionally scaled insulated gate bipolar transistors (IGBTs)

Robustness under high temperature clamped inductive turn-off has been compared systematically among 3300V scaled Insulated Gate Bipolar Transistors (IGBTs) with scaling factor (k) from 1 to 10 by TCAD simulations. Degradation of Reverse Bias Safe Operating Area (RBSOA) has been observed in proportionally scaled IGBT, especially at high turn-off current density. Non-proportional scaling method has been proven to be able to restore the robustness degradation with RBSOA close to the original k=1 case. Moreover, the Rpf (P-floating connecting resistor) adjustment method adds more flexibility to device design, and also improves the overall electrical performance of non-proportionally scaled IGBTs. Besides, the adjustment of Rpf has been found to have minimal effect on RBSOA.
