Abstract

An embodiment provides a semiconductor device comprising: a substrate; a semiconductor structure disposed on the substrate and including a first conductive semiconductor layer, a second conductive semiconductor layer, and an activation layer disposed between the first conductive semiconductor layer and the second conductive semiconductor layer; a bonding layer disposed between the semiconductor structure and the substrate; a cover layer disposed between the bonding layer and the semiconductor structure; and an electrode pad disposed on the cover layer and spaced apart from the semiconductor structure, wherein: the semiconductor structure further comprises a stepped portion at which the lateral surface of the second conductive semiconductor layer, the lateral surface of the activation layer, and the lower surface of the first conductive semiconductor layer are exposed; the stepped portion is disposed at the outer portion of the semiconductor structure; and the cover layer is disposed to extend from a region vertically overlapping the electrode pad to a region vertically overlapping a part of the exposed lower surface of the first conductive semiconductor layer.
