Abstract: A system and method for manufacturing an LED is provided. A preferred embodiment includes a substrate with a distributed Bragg reflector formed over the substrate. A photonic crystal layer is formed over the distributed Bragg reflector to collimate the light that impinges upon the distributed Bragg reflector, thereby increasing the efficiency of the distributed Bragg reflector. A first contact layer, an active layer, and a second contact layer are preferably either formed over the photonic crystal layer or alternatively attached to the photonic crystal layer.

Abstract: A light-emitting diode (LED) device is provided. The LED device has a lower LED layer and an upper LED layer with a light-emitting layer interposed therebetween. A current blocking layer is formed in the upper LED layer such that current passing between an electrode contacting the upper LED layer flows around the current blocking layer. When the current blocking layer is positioned between the electrode and the light-emitting layer, the light emitted by the light-emitting layer is not blocked by the electrode and the light efficiency is increased. The current blocking layer may be formed by converting a portion of the upper LED layer into a resistive region. In an embodiment, ions such as magnesium, carbon, or silicon are implanted into the upper LED layer to form the current blocking layer.

Abstract: A method of fabricating an LED is provided. A doped layer is formed over a silicon substrate. A plurality of dielectric plugs is formed over the silicon substrate. A light-emitting diode (LED) structure is formed over the doped layer. The LED structure is formed between the dielectric plugs. The dielectric plugs are removed, thereby forming a plurality of openings that partially expose the doped layer. The doped layer is converted into a porous layer at least in part by performing an electro-chemical anodization process through the openings. A conductive substrate is formed over the LED structure. Thereafter, the silicon substrate is removed. The removing of the silicon substrate comprises cleaving the porous layer or chemically etching the porous layer.
