Abstract:
A semi-polar LED epitaxial structure includes, from bottom to up: a sapphire substrate; a semiconductor bottom layer structure; and a semiconductor functional layer; wherein: a surface of the semiconductor bottom structure has V pits; and a side of the V pits is a semi-polar surface, corresponding to (1-101) family of crystal planes. A fabrication method includes: providing a sapphire substrate; growing a semiconductor bottom structure over the sapphire substrate to form V pits on a surface, wherein a side of the V pits is a semi-polar surface, corresponding to (1-101) family of crystal planes; and growing a semiconductor functional layer over the semi-polar surface of the semiconductor bottom structure.

Claim (Index 20):
The fabrication method of  claim 15 , wherein:\n the semiconductor functional layer comprises a first semiconductor functional layer and a second semiconductor functional layer, wherein, the first semiconductor functional layer surface has the nanometer V pits; and the nanometer V pits of the first semiconductor functional layer are obtained by quickening growth rate of the semi-polar surface to 5-10 times of that of a conventional polar surface, or extend the growth time to 5-10 times of that of a conventional polar surface.
