Claim Text:
1. A method of manufacturing a substrate for a high efficiency nitride-based light emitting diode on which a nano to micron sized pattern is formed, comprising: a convex section forming step of forming a convex section including any one selected from the group consisting of SiO a crystallization step of annealing the substrate including the convex section and crystallizing the convex section of the nano to micron sized pattern; wherein: in the convex section forming step, the substrate is processed through UV ozone processing, piranha solution processing, O the nano to micron sized pattern comprises a bottom section and the convex section, and a lower end diameter of the convex section is 0.1 to 3 times a light emission wavelength of the light emitting diode, the bottom section and the convex section of the nano to micron sized pattern are alternately repeatedly formed, and a formation cycle of a first convex section and a second convex section adjacent to the first convex section is 0.2 to 6 times the light emission wavelength of the light emitting diode, and the nano to micron sized pattern repeatedly comprises any one selected from the group consisting of a hemispherical shape, a triangular pyramidal shape, a quadrangular pyramidal shape, a hexagonal pyramidal shape, a conical shape and a cut-spherical shape.
