Patent ID: 7083993

Claim:
A method of making a light-emitting device comprising a multi-layer stack of materials including a layer of p-doped material, a light-generating region, and a first layer, the method comprising: bonding the first layer with a substrate; subsequent to bonding the first layer with the substrate, bonding a layer of a reflective material with the layer of p-doped material, the multi-layer stack of materials being between the substrate and the layer of reflective material; and removing the substrate, wherein: the first layer includes a surface having a dielectric function that varies spatially according to a pattern; the reflective material is capable of reflecting at least about 50% of light generated by the light-generating region that impinges on the layer of reflective material; and the substrate is removed after bonding the layer of the reflective material with the layer of p-doped material.
