Abstract:
1. A method of manufacturing a semiconductor light emitting diode, comprising operations of: sequentially forming a first semiconductor layer, an active layer, and a second semiconductor layer on a substrate; in-situ depositing a mask layer on a region of a surface of the second semiconductor layer; selectively growing a third semiconductor layer in a textured structure on the second semiconductor layer by depositing the same material as that of the second semiconductor layer on the second semiconductor layer and the mask layer; and forming a transparent electrode on the third semiconductor, wherein in the in-situ depositing of the mask layer, openings having irregular sizes and periods are formed in the mask layer, without etching, the first semiconductor layer is formed of an n-type semiconductor material and the second semiconductor layer is formed of a p-type semiconductor material, the third semiconductor layer in the textured structure is formed through the openings, the transparent electrode is formed to have a textured structure having a shape which corresponds to that of the textured structure of the third semiconductor layer, and light generated by the active layer is extracted to the outside through the transparent electrode.
