摘要:
A static induction transistor includes a semiconductor substrate with an energy band gap greater than that of silicon, and the semiconductor substrate has a first gate region to which a gate electrode is connected; and a second gate region positioned within a first semiconductor region which becomes a drain region, and the first gate region is in contact with a second semiconductor region which becomes a source region. According to this construction, the OFF characteristics of the static induction transistor are improved.
