Claim:
1. A light emitting diode (LED) package, comprising; a substrate; an n type semiconductor layer formed over the substrate; a plurality of LED cells formed over the substrate, each LED cell comprising an n type semiconductor layer being a part of the n type semiconductor layer formed over the substrate, an active layer formed over the part of the n type semiconductor layer, and a p type semiconductor layer formed over the active layer, the plurality of LED cells comprising at least two separate groups of LED cells, each separate group including two or more LED cells; an insulation layer formed over the n type semiconductor layer surrounding the plurality of LED cells, the insulation layer including a trench that exposes part of the underlying n type semiconductor layer in a part of an area around the LED cells; one n type pad electrode which is connected to and extends from the n type semiconductor layer of the LED cells and is formed on the n type semiconductor layer exposed by the trench, the n type pad electrode forming one common n type electrode layer for all the LED cells; and a p type contact electrode for each separate group of LED cells each of which is connected to and extends from each of the p type electrodes of a respective separate group of LED cells and are formed over the insulation layer.
