Patent ID: 7833809

Claim:
A method of fabricating a light emitting diode structure, comprising: providing a substrate; spreading a metallic material on the substrate, wherein the metallic material is selected from a group consisting of aluminum, magnesium and indium; providing a nitrogen-containing gas so that the metallic material reacts with the nitrogen-containing gas to form a strain-reducing seed layer, wherein the strain-reducing seed layer comprises a plurality of clusters, and a material of the clusters is selected from a group consisting of aluminum nitride, magnesium nitride and indium nitride; forming an epitaxial layer on the strain-reducing seed layer, wherein the epitaxial layer comprises a first type doped semiconductor layer, a light emitting layer and a second type doped semiconductor layer sequentially stacked over the strain-reducing seed layer, and the light emitting layer is formed on a portion of the first type doped semiconductor layer; and forming a first electrode and a second electrode on the exposed first type doped semiconductor layer and the second type doped semiconductor layer respectively, wherein the first electrode is electrically connected to the first type doped semiconductor layer, and the second electrode is electrically connected to the second type doped semiconductor layer.
