Abstract

A first diffusion layer in which phosphor of a low concentration is diffused is formed in a semiconductor body, and a second diffusion layer in which arsenic or antimony of a high concentration is formed in a portion of the upper face of the first diffusion layer. Further, a third diffusion layer in which phosphor of a high concentration is formed in the range of the second diffusion layer on the surface of the semiconductor body in a deeper condition than the first diffusion layer is formed.
