Patent ID: 6998281

Claim:
A method of making a packaged light emitting diode, comprising: forming a first conductivity type semiconductor contact layer on a transparent substrate; forming a semiconductor active layer over a first surface of the first conductivity type semiconductor contact layer; forming a second conductivity type semiconductor contact layer over the active layer; patterning the first conductivity type semiconductor layer, the second conductivity type semiconductor contact layer and the active layer; forming a first metal containing electrode contacting the first conductivity type semiconductor contact layer; forming a second metal containing electrode contacting the second conductivity type semiconductor contact layer to yield a light emitting diode; and forming a packaged light emitting diode containing at least one integrated microoptical element above the light emitting diode, wherein forming the packaged light emitting diode comprises: mounting the light emitting diode in a flip chip configuration on a package, wherein the first electrode electrically contacts a first lead on the package, the second electrode electrically contacts a second lead on the package and the substrate is positioned toward a light emitting surface of the package; forming a transparent encapsulating material layer over the transparent substrate, through which light from the light emitting diode passes; forming a flexible sheet over the encapsulating material layer; and etching the at least one microoptical element on the flexible sheet, through which light from the light emitting diode passes after passage through the encapsulating material layer.
