  • Patent number: 9520441
    Abstract: A method for fabricating a back-illuminated imager which has a pinned back surface is disclosed. A first insulator layer is formed overlying a mechanical substrate. A conductive layer is deposited overlying the first insulator layer. A second insulator layer is formed overlying the conductive layer to form a first structure, an interface being formed between the conductive layer and the second insulator layer, the conductive layer causing band bending proximal to the interface such that the interface is electrically pinned. Hydrogen is implanted in a separate device wafer to form a bubble layer. A final insulator layer is formed overlying the device wafer to form a second structure. The first structure and the second structure are bonded to form a combined wafer. A portion of the combined wafer is removed underlying the bubble layer to expose a seed layer comprising the semiconductor material substantially overlying the second insulator layer.

  • Patent number: 8507884
    Abstract: A light source having a substantially elliptical cross-section for UV curing lamp assemblies is disclosed. The light source has a pair of end sections and a central section of smaller diameter than the end sections. The end sections are each connected to the central section by a tapered section the diameter of each of which decreases from an end that mates with an end section toward an end that mates with the central section. Each of the end sections has a substantially elliptical cross-section. The central section and the tapered sections may have a substantially elliptical cross-section. The aspect ratio of the elliptical cross-section of the end sections and the central section of the light source is preferably about 2:1.
