| titleOfInvention | Semiconductor light emitting device and manufacturing method thereof |
| abstract | The present invention relates to a semiconductor light emitting device and a method for manufacturing the same, which improve light extraction efficiency of a nitride-based LED device and enable direction angle control. In the semiconductor light emitting device according to the present invention, a plurality of protrusions having an inclined surface are formed in an array form on the nitride semiconductor layer, and the plurality of protrusions are each composed of a plurality of stacked transparent conductive films having different refractive indices. The refractive index of the transparent conductive film is formed to have a stepwise decrease between the refractive index of the nitride semiconductor layer and the refractive index of the air layer. Therefore, a plurality of transparent electrodes having different refractive indices are inclined structure to maximize light extraction efficiency and to prevent the scattering effect occurring on the surface of the chip, while directing the light to the light output surface as much as possible. The light output efficiency and the electrical / optical characteristics of the device is greatly improved. In addition, the method of manufacturing a semiconductor light emitting device according to the present invention is very simple compared to other research results, thereby reducing the process cost, and since the surface roughening process is not required, the process is simplified and the semiconductor light emitting device is damaged. It can be prevented that it is possible to improve the reliability of the semiconductor light emitting device. |
