ABSTRACT:
After the active layer including indium is formed, the evaporation preventing layer is formed at a temperature which does not cause liberation of indium. The p-type Al.sub.X Ga.sub.1-X N (0.ltoreq.X.ltoreq.1) or the like is used for the evaporation preventing layer. Increasing the substrate temperature to as high as 1020.degree. C. for forming the upper cladding layer does not cause liberation of indium from the active layer because the evaporation preventing layer is provided. As a result, the composition ratio of indium can be easily controlled and the high-quality active layer and the high-quality interface between the active layer and the upper cladding layer can be provided.
