Abstract:
1. A method of manufacturing a vertical LED, the method comprising: forming a light emission structure in which an n-type GaN layer an active layer, and a p-type GaN layer are sequentially laminated on a substrate; forming a p-electrode on the light emission structure; forming a structure support layer on the p-electrode; removing the substrate to - form an exposed N-polar surface of the n-type GaN layer, after removing the substrate, laser-treating the exposed N-polar surface of the n-type GaN layer to form a Ga layer and a Ga+N layer which are sequentially laminated from the laser-treated surface; and forming an n-electrode on the laser-treated exposed surface of the n-type GaN layer, wherein the laser-treating is performed by laser with a wavelength having energy larger than an energy band gap of GaN.
