The ultra high-speed vertical short channel insulated-gate static induction transistor with uniform operating characteristic which has the drain layer 3 consisting of an epitaxial single crystal layer on the main surface 2 of substrate 1 , the channel layer 4 with thickness 1000 Å or less on the drain layer, the source layer 5 consisting of an epitaxial single crystal layer on the channel layer 4 , and the insulated-gates 6 and 7 on the sidewalls of the drain, the channel, and the source layers. Since the thickness of 1000 Å or less is accurately controlled using the molecular layer epitaxial method and the channel layer 4 is grown up, the X-ray photolithography is not needed. Since the gate oxide film is formed by low temperature CVD using active oxygen, impurity re-distribution does not occur.
