Abstract:
The semiconductor light emitting element is a semiconductor light emitting element comprising a semiconductor layer including a light emitting layer, wherein a surface of the semiconductor light emitting element includes a light extraction surface. At least one of the light extraction surface and an interface between two layers having different refractive indexes in the semiconductor light emitting element is provided with a periodic recessed and projecting structure having a period that exceeds 0.5 times as great as a wavelength of light emitted from the light emitting layer, and a minute recessed and projecting structure located on a surface of the periodic recessed and projecting structure and having an average diameter that is not more than 0.5 times as great as the wavelength of the light.

Claim (Index 14):
A method for manufacturing a semiconductor light emitting element, comprising:\n preparing an element member that forms a semiconductor light emitting element including a semiconductor layer including a light emitting layer; forming a mask layer including a pattern on a region of the element member that forms a light extraction surface of the semiconductor light emitting element; and forming a periodic recessed and projecting structure by partially removing the region that forms the light extraction surface by etching using the mask layer as a mask; wherein the mask layer is a metal mask layer; in the forming a periodic recessed and projecting structure, the periodic recessed and projecting structure is formed and a minute recessed and projecting structure is formed on a surface of the periodic recessed and projecting structure, by performing dry etching using an etching gas; the periodic recessed and projecting structure has a period that exceeds 0.5 times a wavelength of light extracted from the semiconductor light emitting element; and the minute recessed and projecting structure has an average diameter that is not more than 0.5 times the wavelength of the light; wherein the forming the periodic recessed and projecting structure includes:\n the performing dry etching; and \n removing the metal mask layer; \n the period of the periodic recessed and projecting structure is the same as a period of the metal mask layer; in the performing dry etching, a reactant of the metal mask layer and the etching gas adheres to the region that forms the light extraction surface.
