High light efficiency solid-state light emitting structure and methods to manufacturing the same

In one embodiment of an epitaxial LED device, a buffer layer (e.g. dielectric layer) between the current spreading layer and the substitute substrate includes a plurality of vias and has a refractive index that is below that of the current spreading layer. A reflective metal layer between the buffer...
