  • Patent number: 8283744
    Abstract: Methods of forming transparent conducting oxides and devices formed by these methods are shown. Monolayers that contain indium and monolayers that contain molybdenum are deposited onto a substrate and subsequently processed to form molybdenum-doped indium oxide. The resulting transparent conducing oxide includes properties such as an amorphous or nanocrystalline microstructure. Devices that include transparent conducing oxides formed with these methods have better step coverage over substrate topography and more robust film mechanical properties.

  • Patent number: 8258563
    Abstract: A nonvolatile memory device includes a semiconductor substrate having a first well region of a first conductivity type, and at least one semiconductor layer formed on the semiconductor substrate. A first cell array is formed on the semiconductor substrate, and a second cell array formed on the semiconductor layer. The semiconductor layer includes a second well region of the first conductivity type having a doping concentration greater than a doping concentration of the first well region of the first conductivity type. As the doping concentration of the second well region is increased, a resistance difference may be reduced between the first and second well regions.
