Patent ID: 7482189

Claim:
A method of fabricating a LED, comprising: providing a substrate; forming an n-GaN layer on the substrate; patterning the n-GaN layer to form a plurality of protrusions, wherein a side surface of the protrusions is inclined with a first inclination angle α (35°≦α≦90°) with respect to an upper surface of the substrate; forming an active layer on the surface of the n-GaN layer, wherein the surface of the active layer formed on the side surface of the protrusions is inclined with a second inclination angle β (35°≦β≦α) with respect to the upper surface of the substrate; forming a p-GaN layer on the surface of the active layer, wherein the surface of the p-GaN layer formed on the surface of the inclined portion of the active layer is inclined with a third inclination angle γ (20°≦γ≦β) with respect to the upper surface of the substrate; exposing a predetermined area of the n-GaN layer to form an n-electrode thereon; and forming a p-electrode on the p-GaN layer, wherein an inclined surface of the p-GaN layer is formed not to be parallel with an inclined surface of the active layer and a side surface of the protrusions.
