  • Patent number: 8513720
    Abstract: A top gate and bottom gate thin film transistor (TFT) are provided with an associated fabrication method. The TFT is fabricated from a substrate, and an active metal oxide semiconductor (MOS) layer overlying the substrate. Source/drain (S/D) regions are formed in contact with the active MOS layer. A channel region is interposed between the S/D regions. The TFT includes a gate electrode, and a gate dielectric interposed between the channel region and the gate electrode. The active MOS layer may be ZnOx, InOx, GaOx, SnOx, or combinations of the above-mentioned materials. The active MOS layer also includes a primary dopant such as H, K, Sc, La, Mo, Bi, Ce, Pr, Nd, Sm, Dy, or combinations of the above-mentioned dopants. The active MOS layer may also include a secondary dopant.

  • Patent number: 8404302
    Abstract: A solution process is provided for forming a textured transparent conductive oxide (TCO) film. The process provides a substrate, and forms a first layer on the substrate of metal oxide nanoparticles such as ZnO, In2O3, or SnO2. The metal oxide nanoparticles have a faceted structure with an average size greater than 100 nanometers (nm). Voids between the metal oxide nanoparticles have a size about equal to the size of the metal oxide nanoparticles. Then, a second layer is formed overlaying the first layer, filling the voids between the nanoparticles of the first layer, and completely covering the substrate. The result is a continuous TCO film having an average surface roughness that is created by the combination of first and second layers.
