ABSTRACT:
An inventive method includes the steps of: growing a first p-type semiconductor layer of a compound semiconductor containing phosphorus on a substrate; and growing a second p-type semiconductor layer of a compound semiconductor containing arsenic on the first p-type semiconductor layer. While the first p-type semiconductor layer is grown, magnesium is added to the first semiconductor layer. While the second p-type semiconductor layer is grown, a p-type impurity other than magnesium is added to the second semiconductor layer.
