Abstract: PROBLEM TO BE SOLVED: To equalize voltage-current characteristics in first and third quadrants by forming distance and concentration between a gate electrode and a source electrode to be almost the same in distance and concentration between a gate electrode and a drain electrode. SOLUTION: An n<-> -layer 2 with a thickness 20 to 30μm and a low impurity concentration of 10<13> to 10<14> /cm<3> is formed by means of vapor growth on an n<+> -substrate 1, consisting of n-type silicon of high impurity concentration. An SiO2 film 4 is formed, a window 4a is removed by selective etching, and a p-layer consisting of p-type silicon of high impurity concentration is diffused. After the SiO2 film 4 has been removed, an n<-> -layer 4b using SiH4 gas and an n<-> -layer 8 with an impurity concentration and a comparable thickness as that of an n<-> -layer 2 and using SiCl4 gas is formed by means of vapor growth. The voltage-current characteristics symmetrical in the first and third quadrants can be obtained by having the same thickness and concentration of the n<-> -layer 2 of the lower part layer and the n<-> -layer 8 of the upper part layer.
