  • Semiconductor light emitting device and method for fabricating the same
    Patent number: 8993993
    Abstract: Provided are a semiconductor light emitting device and a method for fabricating the same. The semiconductor light emitting device includes a light emitting structure and a pattern. The light emitting structure includes a first-conductivity-type semiconductor layer, an active layer, and a second-conductivity-type semiconductor layer. The pattern is formed on at least one light emitting surface among the surfaces of the light emitting structure. The pattern has a plurality of convex or concave parts that are similar in shape. The light emitting surface with the pattern formed thereon has a plurality of virtual reference regions that are equal in size and are arranged in a regular manner. The convex or concave part is disposed in the reference regions such that a part of the edge thereof is in contact with the outline of one of the plurality of virtual reference regions.
