Abstract
A light emitting diode and a method of manufacturing the light emitting diode are provided. The light emitting diode includes an n-type semiconductor layer, an inclined type superlattice thin film layer, an active layer, and a p-type semiconductor layer. The n-type semiconductor layer is disposed on a substrate. The inclined type superlattice thin film layer is disposed on the n-type semiconductor layer and includes a plurality of thin film pairs in which InGaN thin films and GaN thin films are sequentially stacked. The active layer having a quantum well structure is disposed on the inclined type superlattice thin film layer. The p-type semiconductor layer is disposed on the active layer. Composition ratio of Indium (In) included in the InGaN thin film is increased as getting closer to the active layer. Thus, internal residual strain is reduced, and quantum confinement effect is enhanced, and internal quantum efficiency is increased.
