Abstract

In a static induction transistor, in addition to a first gate layer (4), a plurality of second gate layers (41) having a shallower depth and a narrower gap therebetween than those of the first gate layer (4) are provided in an area surrounded by the first gate layer (4), thereby an SiC static induction transistor with an excellent off characteristic is realized, while ensuring a required processing accuracy during production thereof.
