ABSTRACT:
An N-type impurity is ion-implanted in the exposed surface of a semiconductor substrate, thereby forming N-type diffusion layers. A P-type impurity is ion-implanted in the semiconductor substrate covered with a cover film, thereby forming P-type diffusion layers. A compound film of a semiconductor and a metal is formed on each of the surfaces of the N-type and P-type diffusion layers.
