Abstract
Provided are a light emitting diode (LED) in which a conductive barrier layer surrounding a reflective metal layer is defined by a protective insulating layer, and a method of manufacturing the same. A reflection pattern including a reflective metal layer and a conductive barrier layer is formed on an emission structure in which a first semiconductor layer, an active layer, and a second semiconductor layer are formed. The conductive barrier layer prevents diffusion of a reflective metal layer and extends to a protective insulating layer recessed under a photoresist pattern having an overhang structure during a forming process. Accordingly, a phenomenon where the conductive barrier layer is in contact with sidewalls of the photoresist pattern having an over-hang structure and the reflective metal layer forms points is prevented. Thus, LED modules having various shapes may be manufactured.
