英文摘要	PURPOSE:To give even an optical extracting window an effective electrode function, to increase longitudinal currents in currents flowing through a light- emitting layer consisting of a double hetero-junction and to improve luminous efficiency by forming a GaAlAs layer having low resistance and low Al concentration onto the light-emitting layer and using the GaAlAs layer as the optical extracting window. CONSTITUTION:An n-type GaAs layer 22 as a current constriction layer is deposited on a p-type GaAs substrate 21, a p-type GaAs layer 23 is diffused and formed at the central section of the layer 22, and a p-type GaAlAs clad layer 24 constituting a light-emitting layer consisting of a double hetero-junction, a p-type GaAlAs active layer 25, and an n-type GaAlAs clad layer 26 are laminated and grown on the whole surface containing the layer 23. An n-type GaAlAs layer 27, the composition ratio of Al therein is approximately twice as large as the active layer 25 and impurity concentration thereof extends over 1X10/cm or more, is deposited onto the layer 26, an n type GaAs cap layer 28 and an electrode 29 are shaped onto the layer 27, and an optical extracting window 31 is bored to expose one part of the layer 27. An electrode 30 is also provided onto the back of the substrate 2
