英文摘要	PURPOSE:To form an excellent epitaxial layer onto an Si base body by adopting an InP-GaP group lattice relaxing layer and imparting a graded composition change or shaping a superlattice structure. CONSTITUTION:An InP composition is increased in succession from an N-type GaP composition and an N-type InxGa1-xP graded layer 2 (a lattice relaxing layer), N-type and P-type AlGaInP clad layers 3, 5, an InxGa1-xP active layer 4, a P-type AlGaInP buried layer 6 and an N-type AlGaInP buried layer 7 are formed onto an N-type Si base body. Currents flow through the layers 3, 4, 5 by forward bias applied to electrodes 8, 9, electrons and holes are recombined in the active region 4, and light is emitted. One part of emitted beams is confined by the layers 3, 5, 6, 7 having refractive indices lower than the active region, and emitted in the direction vertical to sectional structure. Accordingly, the crystallizability of a light-emitting region shaped onto the layers is improved, thus acquiring an excellent light-emitting device.
