摘要 | PURPOSE:To obtain a semiconductor light-emitting element and a semiconductor laser having excellent current injection efficiency and a high radiant power output by forming a current block layer substantially in parallel with the main surface on a substrate and a recessed section shaped substantially vertically to the main surface on the substrate and forming a P-N junction mainly onto the side face of the recessed section. CONSTITUTION:A semiconductor substrate 101, a light-emitting layer, which is shaped to the main surface of the semiconductor substrate 101, has a P-N junction 108 and emits light in the direction substantially vertical to said main surface in the vicinity of the P-N junction 108, a current block layer 130, in which a semiconductor light-emitting device with electrodes 106, 107 injecting currents to the light-emitting layer is formed substantially in parallel with said main surface on the substrate 101, and a recessed section 140 formed substantially vertically to said main surface to a laminating section on the substrate 101 are provided, and the P-N junction 108 is formed along the side face of the recessed section 140. The cylindrical recessed section 140 is shaped to an N-type GaAs epitaxial layer 102, and Zn, etc., are diffused to the internal side face of the recessed section 140 and a P-type diffusion region 131 is formed. |
