intensity in SiC chips unavoidably tends to increase; in particular, the intensity of the electric field to be applied to the gate oxide at the trench bottom becomes high. Therefore, SiC-MOSFETs require special consideration, unlike Si trench MOSFETs. Figure 3 illustrates the structure of a trench MOSFET that we have been developing.
