Abstract
A UV light emitting diode includes a substrate having a plurality of holes surrounded by a flat surface, a first conductivity type semiconductor layer disposed on the substrate, a second conductivity type semiconductor layer disposed on the first conductivity type semiconductor layer, an active layer disposed between the first conductivity type semiconductor layer and the second conductivity type semiconductor layer. A distance from the flat surface to the active layer is smaller than a distance from bottom surfaces of the plurality of holes to the active layer. The flat surface is in contact with the first conductivity type semiconductor layer.
