Using the oxide film mask 11 patterned as above, p-type dopant ions are implanted. Then, the p<->-type layers 6 and 7 partially overlapping each other are obtained through thermal diffusion. At this point, the thermal diffusion is executed under such a condition that the mask width of a region sandwiched between the openings 12 and 13 of the oxide film mask 11 is made almost equal to the diffusion depth of thermal diffusion, whereby the p<->-type layer 7 region formed through multiple diffusion, as a whole, is lower than the p<->-type layer 6 in dopant concentration per unit area. A doped layer high in reverse breakdown strength can be obtained.
