Claim Text:
1. A light-emitting device, comprising: a first semiconductor layer; an active layer formed under the first semiconductor layer; a second semiconductor layer formed under the active layer; a first electrode electrically connected to the first semiconductor layer and a second electrode electrically connected to the second semiconductor layer, the first and second electrodes form a layout, comprising, in a top view, a first region and a second region; a metal pattern comprising a first metal and designed to correspond the layout, the metal pattern being denser in the second region than in the first region; a transparent conductive oxide layer on the first semiconductor layer; and a diffusion region formed within the transparent conductive oxide layer and comprising diffused atoms of the first metal, wherein, during operation of the light-emitting device, electrical current in the transparent conductive oxide layer has a higher current density under the first region than under the second region.
