VERTICAL LIGHT EMITTING DIODE AND FABRICATION METHOD

摘要

A vertical LED with current blocking structure and its associated fabrication method involve an anisotropic conductive material and a conductive substrate with concave-convex structure. The anisotropic conductive material forms a bonding layer with vertical conduction and horizontal insulation between the concave-convex substrate and the light-emitting epitaxial layer, thereby forming a vertical LED with current blocking function.

1. A vertical light emitting diode (LED), comprising:
a conductive substrate including a front surface and a back surface, wherein the front main surface has a patterned concave-convex structure; an anisotropic conductive material layer disposed over the front surface of the conductive substrate with the patterned concave-convex structure, and forming electrical coupling with a convex portion of the conductive substrate and non-electrical coupling with a concave portion of the conductive substrate, thereby forming a current blocking structure; and a light emitting epitaxial structure formed over the anisotropic conductive material layer.
