Semiconductor light-emitting element and method of manufacturing the same

摘要

There is disclosed a semiconductor light-emitting element comprising a substrate (10) having a first surface and a second surface, and a semiconductor laminate formed on the first surface of the substrate and containing a light-emitting layer (12) and a current diffusion layer (15) having a light-extracting surface, which is characterized in that the light-emitting element is provided with a light-extracting surface which is constituted by a finely recessed/projected surface, 90% of which is constructed such that the height of the projected portion thereof having a cone-like configuration is 100 nm or more, and the width of the base of the projected portion is within the range of 10-500 nm.
