Top-emitting N-based light emitting device and method of manufacturing the same
First Claim
1. A method of manufacturing an N-based light emitting device, the method comprising:
- forming a transparent conductive thin film on a p-type clad layer of a light emitting structure in which an n-type clad layer, an active layer, and the p-type clad layer are sequentially stacked on a substrate;
wet-etching the transparent conductive thin film; and
annealing the wet-etched transparent conductive thin film.

Abstract
Provided is a top-emitting N-based light emitting device and a method of manufacturing the same. The N-based light emitting device may include an n-type clad layer, an active layer, a p-type clad layer, and a transparent conductive thin film which may be sequentially stacked on a substrate. The transparent conductive thin film may have a surface nano-scale patterned by wet-etching and then annealing without using a mask for improving the light extraction rate. A light emitting device having a higher brightness may be prepared by increasing or maximizing the light extraction rate by employing the transparent conductive thin film having the surface patterned by wet-etching and then annealing.
