Abstract: V-groove trench MOSFETs with the 4H-SiC{0-33-8} face as the trench sidewall for the channel region have been investigated. The on-resistance and breakdown voltage strongly depend on the aperture ratio of the buried p + regions. The threshold voltage is 2.3 V at 175°C, which shows the VMOSFETs have tolerability for an erroneous ignition …
