Abstract
A semiconductor device according to an embodiment includes: a light emitting structure including a first conductive semiconductor layer, an active layer under the first conductive semiconductor layer, a second conductive semiconductor layer under the active layer, and a plurality of recesses exposing a lower portion of the first conductive semiconductor layer; at least one pad arranged outside the light emitting structure and arranged to be adjacent to at least one edge; and a plurality of insulation patterns arranged in the recesses and extending to a lower surface of the light emitting structure, in which widths of the plurality of insulation patterns are reduced as the insulation patterns become further away from the pad. The semiconductor device according to the embodiment may prevent a current from being focused on a recess area adjacent to the pad.
