1. A lateral structure light-emitting diode (LED) chip comprising:
a substrate;
a light-emitting structure disposed on the substrate and comprising an active layer disposed between a first conductivity-type semiconductor layer and a second conductivity-type semiconductor layer, with the light-emitting structure including an L shaped cut-out area cut out from a single corner of the light-emitting structure in which the active layer and the first conductivity-type semiconductor layer are removed to expose a corresponding L shaped portion of the second conductivity-type semiconductor layer;
a pair of dielectric layers disposed above the light-emitting structure with one of the pair of dielectric layers being disposed in the cut-out area;
a pair of wire bond pads disposed on the pair of dielectric layers, respectively, wherein the pair of wire bonds comprise a first wire bond pad disposed above the first conductivity-type semiconductor layer and a second wire bond pad disposed above the second conductivity-type semiconductor layer and in the cut-out area; and
a doped wiring extension extending from the second wire bond pad and into the light-emitting structure.
