Abstract

Abstract A diamond semiconductor device has a diamond semiconductor with a pn junction formed by vapor phase synthesis process. The device has a p-type semiconductor portion containing boron as an impurity, and an n-type semiconductor portion containing lithium as an impurity. This semiconductor device is produced by vapor phase synthesis having the steps of introducing boron as an impurity into the p-type semiconductor portion, and introducing lithium as an impurity into said n-type semiconductor portion.
