Abstract:
A method for making a semiconductor device comprising: depositing at least one Group II-VI compound semiconductor layer comprising at least one Group II element selected from the group consisting of zinc, magnesium, manganese, beryllium, cadmium and mercury and at least one Group VI element selected from the group consisting of oxygen, sulfur, selenium and tellurium onto a Group III-V compound semiconductor layer comprising at least one Group III element selected from the group consisting of gallium, aluminum, boron and indium and at least one Group V element selected from the group consisting of nitrogen, phosphorus, arsenic, antimony and bismuth; whereinbefore depositing said Group II-VI compound semiconductor layer, a particle beam composed of at least one Group II element selected from the group consisting of zinc, magnesium, beryllium, cadmium and mercury is radiated onto the surface of said Group III-V compound semiconductor layer for a multiplet structure in the<110>direction on said surface observed by RHEED to change from a quadruplet pattern (4.times.) to a singlet pattern (1.times.).
