摘要：
An object of the present invention is to provide a light emitting diode having a heterogeneous material structure and a method of manufacturing thereof, in which efficiency of extracting light to outside is improved by forming depressions and prominences configured of heterogeneous materials different from each other before or in the middle of forming a semiconductor material on a substrate in order to improve the light extraction efficiency.
