Abstract
A flip-chip light LED includes: a substrate; an epitaxial layer on the substrate, wherein, the epitaxial layer comprises: a first semiconductor layer, a second semiconductor layer and a light emitting layer between the first semiconductor layer and the second semiconductor layer; at least one opening structure, which is at the epitaxial layer edge and extends to the substrate surface, making parts of the side wall of the epitaxial layer and the substrate surface exposed, such that the epitaxial layer is divided into an epitaxial bulk layer and a barrier structure; and an insulating layer on the opening structure as the metal electrode isolating layer.
