20140057377 | METHOD FOR MANUFACTURING DEVICE - A method for manufacturing a device having a concavo-convex structure includes forming an organic resist film on an n-type semiconductor layer in which a fine concavo-convex structure is to be formed; forming a silicon-containing resist film on the organic resist film; patterning the silicon-containing resist film by nanoimprint; oxidizing the silicon-containing resist film with oxygen-containing plasma to form a silicon oxide film; dry-etching the organic resist film by using the silicon oxide film as an etching mask; dry-etching the n-type semiconductor layer by using the silicon oxide film and the organic resist film as an etching masks; and removing the silicon oxide film and the organic resist film. | 02-27-2014 |
20140167066 | LIGHT EMITTING ELEMENT AND METHOD FOR MANUFACTURING SAME - A semiconductor light emitting element including, in a light extraction layer thereof, a photonic crystal periodic structure including two systems (structures) with different refractive indices. An interface between the two systems (structures) satisfies Bragg scattering conditions, and the photonic crystal periodic structure has a photonic band gap. | 06-19-2014 |
20160042102 | SEMICONDUCTOR LIGHT EMITTING ELEMENT AND METHOD FOR PRODUCING THE SAME - A semiconductor light emitting element with a design wavelength of λ, comprising a photonic crystal periodic structure having two structures with different refractive indices at each of one or more interfaces between layers that form the light emitting element. The period a and the radius R that are parameters of each of the one or more periodic structures and the design wavelength λ satisfy Bragg conditions. The ratio (R/a) between the period a and the radius R is a value determined so that a predetermined photonic band gap (PBG) for TE light becomes maximum for each periodic structure. The parameters of each periodic structure are determined so that light extraction efficiency of the entire semiconductor light emitting element with respect to light with the wavelength λ becomes maximum as a result of conducting a simulation analysis with a FDTD method using as variables the depth h of the periodic structure that is of greater than or equal to 0.5a and the period a and the radius R that are determined for each order m of the Bragg conditions. | 02-11-2016 |
