Abstract:
A semiconductor light emitting device comprising:a semiconductor substrate; a semiconductor laminating portion provided on said semiconductor substrate and including a light emitting layer forming portion having at least an n-type layer and a p-type layer and a window layer; an upper electrode partially provided on said semiconductor laminating portion; a lower electrode provided on a back surface of said semiconductor substrate; and a current blocking layer which is provided on a part of a surface of said semiconductor laminating portion beneath said upper electrode, wherein a surface of said current blocking layer and the surface of said semiconductor laminating portion are flat without a step, wherein said current blocking layer is formed of a high resistance layer caused by a crystalline defect of a semiconductor layer of the surface of said semiconductor laminating portion and wherein said semiconductor layer of the surface of said semiconductor laminating portion is made of AIGaAs or InGaP, and As or P of a part of said semiconductor layer is evaporated, whereby the crystalline defect partially occurs in said semiconductor layer and said current blocking layer is formed in the high resistance layer.
