SEMICONDUCTOR LIGHT EMITTING ELEMENT AND METHOD OF MANUFACTURING SAME

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor light emitting element capable of improving extraction efficiency of light, and a method of manufacturing the same.

SOLUTION: The semiconductor light emitting element 1 has a support substrate 2 and a semiconductor laminate structure 6 including an MQW active layer 13 emitting the light and an uppermost n-GaN layer 14. A plurality of conic protrusions 14a are formed on the upper surface of the n-GaN layer 14 of the structure 6. Where wavelength of the light emitted from the MQW active layer is λ and a refractive index of the n-GaN layer 14 is n, the protrusion 14a is formed to satisfy WA≥λ/n in which WArefers to an average of width W of the bottom face of the protrusion 14.
