Abstract:
1. A nitride semiconductor light emitting device array comprising: a dielectric layer formed on a first conductivity lower nitride semiconductor layer and having a plurality of windows formed therethrough; a plurality of hexagonal pyramid light emission structures each selectively grown from a surface of the first conductivity lower nitride semiconductor layer exposed through each of the plurality of windows and onto a peripheral area of the plurality of windows of the dielectric layer, each of the hexagonal pyramid light emission structures comprising a first conductivity upper nitride semiconductor layer, an active layer and a second conductivity nitride semiconductor layer formed in this order; a reflective electrode formed on the plurality of hexagonal pyramid light emission structures respectively to be contacted with the second conductivity nitride semiconductor layer; and a conductive support structure formed on the reflective electrode layer and filling spaces between the plurality of hexagonal pyramid light emission structures to provide a substantially planar surface, wherein the plurality of windows are disposed in a grid such that centers of adjacent windows are disposed in perpendicular rows and columns, and wherein a predetermined interval spacing between adjacent rows and columns is such that two opposing side surfaces of one of the plurality of hexagonal pyramid light emission structures abut side surfaces of other adjacent ones of the plurality of hexagonal pyramid light emission structures, and wherein a sum of side surface areas of the plurality of hexagonal pyramid light emission structures is greater than a total growth surface area of the dielectric layer.
