Abstract
A light emitting diode (LED) comprises a substrate, an epitaxial layer and an aluminum nitride (AlN) layer sequentially disposed on the substrate. The AlN layer comprises a plurality of stacks separated from each other, wherein the epitaxial layer entirely covers the plurality of stacks of the AlN layer. The AlN layer with a plurality of stacks reflects upwardly light generated by the epitaxial layer and downwardly toward the substrate to an outside of LED through a top plan of the LED. A method for forming the LED is also disclosed.
