Abstract:
1. A method for manufacturing a light emitting device, comprising: forming an n-type nitride semiconductor layer on a substrate; forming an active layer on the n-type nitride semiconductor layer; forming an AlN/GaN layer of a super lattice structure by alternately growing an AlN layer and a GaN layer on the active layer; and forming a p-type nitride semiconductor layer on the AlN/GaN layer of the super lattice structure, wherein the AlN layer is doped with a p-type dopant, and the GaN layer is a u-GaN layer, wherein the forming of an AlN/GaN layer of a super lattice structure is performed in a reaction chamber, and comprises: wherein, when repeating (a) to (d), the p-type dopant source gas is supplied in different flows into the reaction chamber, such that the AlN layers comprise different amounts of the p-type dopant.
