Patent ID: 7271424

Claim:
A light-emitting diode, comprising: a sub-mount; a first conductivity type substrate deposed on the sub-mount; a reflector layer deposed between the sub-mount and the first conductivity type substrate; a first conductivity type buffer layer deposed on the first conductivity type substrate, wherein a plurality of openings are formed in a stacked structure, and the stacked structure comprises the first conductivity type substrate and the first conductivity type buffer layer, and the reflector layer conformally covers on the stacked structure; a first conductivity type distributed Bragg reflector layer deposed on the first conductivity type buffer layer; a first conductivity type cladding layer deposed on the first conductivity type distributed Bragg reflector layer; an active layer deposed on the first conductivity type cladding layer; a second conductivity type cladding layer deposed on the active layer; and a second conductivity type window layer deposed on the second conductivity type cladding layer.
