Patent ID: 8859413

Claim:
A method of manufacturing a light emitting device, comprising: growing GaN single crystals by forming a buffer layer including a TiN group material contacting a silicon substrate, forming a nano-pattern including silicon oxide on the buffer layer, and growing the GaN single crystals on the buffer layer and the nano-pattern; forming an n-GaN layer on the buffer layer and the nano-pattern; forming an active layer on the n-GaN layer; forming a p-GaN layer on the active layer; and forming a p-electrode and an n-electrode, one of the p-electrode and the n-electrode being disposed on a surface of the silicon substrate, wherein forming the nano-pattern includes forming a silicon oxide layer by depositing SiO 2 on the buffer layer, forming a plurality of metal nano-dots on the silicon oxide layer, and dry etching the silicon oxide layer using the metal nano-dots as a mask.
