Patent ID: 10483247

Abstract:
The semiconductor element according to an embodiment comprises: a light-emitting structure comprising a p-type semiconductor layer, an active layer disposed under the p-type semiconductor layer, and an n-type semiconductor layer disposed under the active layer; a protective layer disposed on the side surface and upper surface of the light-emitting structure; a p-type contact layer disposed over the p-type semiconductor layer; and an n-type contact layer disposed under the n-type semiconductor layer, wherein: the width of the lower surface of the n-type semiconductor layer is provided greater than that of the lower surface of the p-type semiconductor layer; the width of the upper surface of the n-type contact layer is provided greater than that of the upper surface of the n-type semiconductor layer; and the angle between the lower surface of the n-type semiconductor layer and the side surface of the light-emitting structure may be 30-80 degrees.
