How is the robustness of SIC compared with IGBT and MOSFET?
Does SIC have similar failure mechanisms as MOSFET, or does SIC have some unique failure mechanisms?

Most of the failure mechanism is the same as Si based technology. However, the gate oxide (GOX) reliability is the very special reliability topic for SiC MOSFET. Infineon has spend a lot of effort to enhance the GOX reliability. Now, we have achieved the total failure rate of SiC MOSFET (including GOX) is the same as the Si based technology.
