ABSTRACT:
A method for manufacturing a semiconductor device comprises evaporating phosphorus on a silicon substrate to form a thin phosphorus layer and growing gallium phosphide on the substrate having the thin phosphorus layer, heterojunction being defined between the substrate and the semiconductor layer only in the region where the thin film had been formed prior to the growth of gallium phosphide.
