  • Patent number: 7083993
    Abstract: Methods of making multi-layer light-emitting devices and related components and systems are disclosed. The light-emitting devices can include a layer of reflective material bonded with a layer of p-doped material. The reflective material can be capable of reflecting at least about 50% of light generated by a light-generating region that impinges on the layer of reflective material.

  • Patent number: 7074631
    Abstract: A method includes disposing a planarization layer on a surface of a layer of semiconductor material and disposing a lithography layer on a surface of the planarization layer. The method also includes performing nanolithography to remove at least a portion of the planarization layer, at least a portion of the lithography layer and at least a portion of the layer of semiconductor material, thereby forming a dielectric function in the surface of the layer of semiconductor material that varies spatially according to a pattern.
