Semiconductor light emitting device substrate including an uneven structure having convex portions, and a flat surface therebetween

Abstract

A semiconductor light emitting device substrate including an uneven structure on one surface, the uneven structure including numerous convex portions and a flat surface between the convex portions, and multiple areas in which the central portions of seven adjacent convex portions are continuously and positionally aligned to become six vertices and intersection points of diagonal lines of a regular hexagon, and the area, shape and lattice orientation of the plurality of areas are random. A semiconductor light emitting device including the semiconductor light emitting device substrate; and a semiconductor functional layer laminated on the semiconductor light emitting device substrate.
