Abstract

PURPOSE:To eliminate any excessive impurity dopant by a method wherein, after growing a GaAlAs layer on a substrate, the substrate is removed to form an active layer further forming electrode layers on the opposite side surfaces. CONSTITUTION:A GaAlAs layer 2 is grown on a GaAs substrate 1 by liquid epitaxial process. The substrate 1 is removed to expose the GaAlAs layer 2 for finishing an exposed surface 4 as a mirror surface. Next, PN junction layers 5 are grown on the exposed surface by liquid epitaxial process. Thus, electrode layers 6, 7 as light emitters are formed respectively on the end surface of GaAlAs layer 2 and the surface of PN junction layer 5. Through these procedures, the electrode layers 6, 7 can be formed on the growing end surface sides of the GaAlAs layer 2 to assure the excellent electrode characteristics using less impurity dopant.
