Claim 18:
19. A deep UV light emitting diode, comprising:
a substrate;
an n-type semiconductor layer located on the substrate;
a mesa disposed on the n-type semiconductor layer, including an active layer and a p-type semiconductor layer, and including a plurality of vias exposing the n-type semiconductor layer;
an n-ohmic contact layer contacting the n-type semiconductor layer exposed around the mesa and the n-type semiconductor layer exposed to the plurality of vias, respectively;
first reflection layers covering upper and side surfaces of the n-ohmic contact layer and located lower than the mesa;
a second reflection layer connected to the first reflection layers and extending to an upper region of the mesa from the first reflection layers;
an n-bump connected to the second reflection layer; and
a p-bump electrically connected to the p-type semiconductor layer, wherein the n-ohmic contact layer, the first reflection layers, and the second reflection layer include Al.
