Abstract: PURPOSE:To enable a high-speed type diode to be restrained from increasing in forward voltage and enhanced in reverse recovery characteristic by a method wherein the semiconductor substrate of the diode is set an off angle 3-5 degrees. CONSTITUTION:An N<+>-type Si substrate 1 which is sliced at an angle of 4 degrees inclined to a <010> inclination direction and whose primary face is a (100) plane is employed. An N epitaxial layer 2 is provided onto a substrate 1, and a P<+>-type Si layer 3 in deep junction with the N-layer 2 and a P<->-type Si layer 4 in shallow junction with the N-layer 2 are formed so as to be alternately arranged at an adequate interval. An Al layer 6 is formed taking advantage of the opening of an SiO2 film 5, and a Cr layer 7 is deposited on the N<+> substrate 1. When a reverse voltage is applied to a P-N junction, carriers in a region b small in thickness in the N-layer are quickly lessened in number, and carriers in a region large in thickness are gradually decreased in number. Therefore, a semiconductor device of this design has such characteristics that di/dt is small at a reverse recovery or the device recovers softly at a reverse recovery.
