发明名称 SEMICONDUCTOR LIGHT EMITTING ELEMENT
摘要 PROBLEM TO BE SOLVED: To provide a semiconductor light emitting element, which has a structure wherein a uniform current is made to flow to an LED operating region uniformly so as not, to generate the unbalanced concentration of a current when an LED is operated, and in which, as a result, the product life of the LED is made long. SOLUTION: A first clad layer 12, an active layer 13, a second clad layer 14, a current diffusion layer 15 and a contact layer 16 are laminated sequentially on a substrate 11. A lower-part electrode 10 is formed on the rear side of the substrate 11 on the opposite side of a laminated structure. A current blocking layer 17 is formed partly on the surface of the laminated structure. A translucent transparent electrode 18 covers the current blocking layer 17 and the second clad layer 14. An upper-part electrode 19 is connected to the surface of the transparent electrode 18, it is formed so as to cover the upper part of the current blocking layer 17, it is extended up to the surface of the neighboring transparent electrode 18 via a step by the side part in the whole circumference of the current blocking layer 17, and it compensates the coverage of the transparent electrode 18 in the step of the current blocking layer 17.
