This paper reviews advanced gate dielectric processes for SiC MOSFETs. The poor quality of the SiO 2 /SiC interface severely limits the value of the channel field-effect mobility, especially in 4H-SiC MOSFETs. Several strategies have been addressed to overcome this issue. Nitridation methods are effective in increasing the channel mobility …
