Patent ID: 8552441

Claim:
An AlGaInP light-emitting diode (LED) having a vertical structure, comprising: an epitaxial layer, comprising an n-type textured confined layer, an n-type contact layer, an active layer, a p-type confined layer and a p-type window layer that are stacked; a stacked transparent layers having at least two periods, formed below the p-type window layer, wherein the stacked transparent layers comprises stacked transparent conducting layers and transparent dielectric layers; a series of through-holes, distributed in the stacked transparent layers; a total-reflection metal layer, formed below the stacked transparent layers, wherein the total-reflection metal layer fills up the through-holes; a permanent substrate, bonded with the epitaxial layer via a metal bonding layer, wherein the total-reflection metal layer is in contact with the bonding layer; an n-type extension electrode, in ohmic contact with the n-type contact layer; and an n-type pad, formed on the n-type textured confined layer.
