摘要：

The neutron-induced single event burnout (SEB) failure is investigated for SiC metal-oxide semiconductor field-effect transistor (MOSFET) by conducting spallation neutron irradiation at different temperatures in the range of -25 degrees C similar to 125 degrees C. The SEB failure rates of SiC MOSFETs at different temperatures and voltages are calculated based on the accelerated experimental results. It shows that the failure rates increase exponentially with drain bias voltages and decrease exponentially with temperatures. An empirical formula of failure rate as a function of voltage and temperature is established for the 900 V SiC MOSFET. The influence of temperature on SEB effect is also studied by technology computer aided design (TCAD) simulations.
