摘要：
The bipolar degradation of Deep-p encapsulated 4H-SiC trench MOSFETs was investigated by using the pulse-current conduction system up to ultra-high current density. The fabricated MOSFETs exhibit the low hole injection compared with the PN diodes and conventional MOSFETs, resulted in the fabricated MOSFETs suppressed the bipolar degradation up to a current density of 3000 A/cm(2).
