摘要:
In a semiconductor light emitting device, a semiconductor light emitting element has a light extracted surface on which a plurality of convex structures is formed. The convex structures each have a conical mesa portion constituting a refractive index gradient structure, a cylindrical portion constituting a diffraction grating structure, and a conical portion constituting a refractive index gradient structure. The mesa portion, cylindrical portion, and conical portion are arranged in this order from the light extracted surface. The period between the convex structures is longer than 1/(the refractive index of an external medium+the refractive index of the convex structures) of an emission wavelength and equal to or shorter than the emission wavelength. The circle-equivalent average diameter of the cylindrical portion is ⅓ to 9/10 of that of the bottom of the mesa portion.

摘要:
A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved.The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index. The surface of such light-emitting element is obtained by forming a thin film on the surface of the light-emitting element using a resin composition which contains a block copolymer or graft copolymer and forms a micophase-separated structure in a self-organization manner; selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface; and etching the surface of the light-emitting element using the remaining phase as an etching mask.
