Patent ID: 8642994

Claim:
A light emitting diode array, comprising: a substrate having an array comprising a plurality of light emitting diode (LED) chips disposed thereon, wherein each of the LED chips is isolated from another LED chip adjacent thereto by a trench, and each of the LED chips comprises: a buffer layer; a first type semiconductor layer over the buffer layer, having a relatively higher second platform area and a relatively lower first platform area; an active layer over the second mesa area; a second type semiconductor layer over the active layer; a first type electrode over the first platform area; and a second type electrode over the second type semiconductor layer; a dielectric layer covering a surface of the substrate exposed by the trench, sidewalls of the LED chips, and portions of the first semiconductive layer and the second type semiconductor layer adjacent to the trench, exposing the first type electrode and the second electrode; a plug filling the trench and disposed over the dielectric layer and surrounded by the dielectric layer; and a conductive connection layer over the plug and the dielectric layer to connect the first type electrode of each of the LED chips with the second type electrode of the LED chips adjacent thereto.
