Abstract
A light-emitting diode (LED) includes an epitaxial laminated layer with an upper surface and an opposing lower surface, the LED including: a first-type semiconductor layer; an active layer; and a second-type semiconductor layer. A portion of the first-type semiconductor layer and the active layer are etched to expose a portion of the second-type semiconductor layer; a first electrode and a second electrode are disposed over the lower surface of the epitaxial laminated layer; the first electrode is disposed over a surface of the first-type semiconductor layer; the second electrode is disposed over a surface of the exposed second-type semiconductor layer; a transparent medium layer over the upper surface of the epitaxial laminated layer, having a refractive index n> 1.6; a transparent bonding medium layer over one upper surface of the transparent medium layer, having a refractive index n<n1.
