Abstract
PURPOSE:To restrain a semiconductor light emitting element from deteriorating so as to lengthen the span of life by a method wherein In is doped into a GaAs epitaxial film which composes a bufter layer, where the amout of In to be doped is 0.001-1% of Ga by mole. CONSTITUTION:An n-type In doped GaAs buffer layer 2 and an n-type GaAs active layer 3 are successively formed on a GaAs substrate 1, where In 0.001-1% if Ga by mole is doped into a GaAs epitaxial layer which composes the buffer layer 2. Then, the mismatching between the substrate 1 and the buffer layer 2 is eliminated, the dislocation of the buffer layer 2 from the sub strate 1 is prevented, and a p-n junction is formed, where an injection current is small. By these processes, a semiconductor light emitting element is prevented from deteriorating, and thus it can be lengthened in life.
