Vertical-channel type junction sic power fet and manufacturing same


In order to secure the performance of a sic-based jfet having an impurity diffusion rate lower than silicon-based one, a gate depth is secured while precisely controlling a distance between gate regions, instead of forming gate regions by ion implantation into the side wall of a trench. This means that a channel region defined by a gate distance and a gate depth should have a high aspect ratio.
