Patent ID: 7034340

Claim:
A light-emitting diode array comprising a conductive layer formed on a substrate; a plurality of separate light-emitting portions formed on said conductive layer; a first electrode formed on at least part of an upper surface of each of said light-emitting portions; and a second electrode formed on said conductive layer adjacent to said light-emitting portions, wherein said second electrode is a common electrode for operating said light-emitting portions, and wherein said conductive layer is removed between adjacent light-emitting portions except for areas constituting current paths to the light-emitting portions, which light-emitting diode comprises first and third mesa-etched grooves separating said light-emitting portions from bonding portions, and second mesa-etched grooves separating said light-emitting portions from each other, thereby forming a plurality of separate light-emitting portions; and wherein said second mesa-etched grooves remove said conductive layer between adjacent light-emitting portions, thereby controlling current paths between said first electrodes and said second electrode.
