Claim 12:
13. 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, and including an active layer and a p-type semiconductor layer;
an n-ohmic contact layer in contact with the n-type semiconductor layer; and
a p-ohmic contact layer in contact with the p-type semiconductor layer, wherein:
the mesa includes a plurality of vias exposing the n-type semiconductor layer,
the mesa has an elongated rectangular shape along a longitudinal direction,
the mesa has a mirror symmetrical structure with respect to a first plane passing through a center of the mesa along the longitudinal direction of the mesa, and with respect to a second plane passing through the center of the mesa along a direction perpendicular to the longitudinal direction of the mesa.
