Abstract
Disclosed in an embodiment is a semiconductor device comprising: a substrate; a light emitting structure including a first conductive semiconductor layer and a second conductive semiconductor layer, which are arranged on the substrate, an active layer arranged between the first conductive semiconductor layer and the second conductive semiconductor layer, a concave part that is concave on the second conductive semiconductor layer toward the first conductive semiconductor layer, and a recess; a first electrode arranged on the concave part and electrically connected to the first conductive semiconductor layer; a second electrode arranged on the light emitting structure and electrically connected to the second conductive semiconductor layer; a first pad arranged on the first electrode; and a second pad arranged on the second electrode, wherein the recess separates the second conductive semiconductor layer and the active layer into an active region and an inactive region, and the first pad vertically overlaps the concave part, the second conductive semiconductor layer on the inactive region, and the recess.
