英文摘要 | PURPOSE:To improve a semiconductor laser in property and manufacturing yield by a method wherein an epitaxial layer which is provided with a flat face and high in carrier concentration is used as a current constriction layer. CONSTITUTION:A semiconductor laser is composed of a P-type substrate 7 and an epitaxial layer highly doped with Sn used as a current constriction layer 6. The epitaxial layer using Sn as a dopant is hard to degrade the evenness of its superficial layer even if a large amount of dopant is used. Therefore, when an epitaxial layer highly doped with Sn is used as an n-type current constriction layer, the surface of the epitaxial layer is made flat notwithstanding that the layer is high in carrier concentration. By these processes, a semiconductor laser is decreased not only in a threshold current but also in the variability of property and improved in a manufacturing yield. |
