英文摘要	PURPOSE:To prevent emission light from shifting to be shorter in wavelength and an oscillation threshold current from increasing by a method wherein a semiconductor light emitting element of InGaAlP double hetero-junction structure is provided, where an active layer is doped with Si as an N-type dopant. CONSTITUTION:In an InGaAlP double hetero-junction type light emitting element, an In1-y(Ga1-xAlx)Py (0<=x<1, yapprox.=0.5) active layer 4 is doped with Si as a dopant which does not change the active layer 4 in crystal structure to prevent a dopant contained in a P-type InGaAlP clad layer 5 from diffusing into the active layer 4. By this setup, the emission light of a light emitting element is prevented from shifting to be shorter in wavelength and the oscillation threshold current is also prevented from increasing, and the element can be improved in yield and reliability.
