Claim Text:
1. A light-emitting device comprising: a substrate; a semiconductor stack layer on the substrate, comprising a first semiconductor layer; an active layer formed on the first semiconductor layer; and a second semiconductor layer formed on the active layer, wherein the second semiconductor layer comprises a first surface composed of a first non-recess region and a first recess region closer to the active layer than the first non-recess region, the first semiconductor layer comprises a second surface composed of a second recess region and a second non-recess region; a first current blocking layer comprising an insulating material formed on the first recess region; a second current blocking layer formed on the second recess region; a first electrode on the first recess region and separated from the first current blocking layer; and a second electrode located right above the second recess region.
