  • Patent number: 7628896
    Abstract: A transparent conductive oxide (TCO) based film is formed on a substrate. The film may be formed by sputter-depositing, so as to include both a primary dopant (e.g., Al) and a co-dopant (e.g., Ag). The benefit of using the co-dopant in depositing the TCO inclusive film may be two-fold: (a) it may prevent or reduce self-compensation of the primary dopant by a more proper positioning of the Fermi level, and/or (b) it may promote declustering of the primary dopant, thereby freeing up space in the metal sublattice and permitting more primary dopant to create electrically active centers so as to improve conductivity of the film. Accordingly, the use of the co-dopant permits the primary dopant to be more effective in enhancing conductivity of the TCO inclusive film, without significantly sacrificing visible transmission characteristics. An example TCO in certain embodiments is ZnAlOx:Ag.

  • Patent number: 7450233
    Abstract: A measuring device includes several sequentially disposed coating chambers for measuring optical properties of coated substrates. These coating chambers are separated from one another by partitioning walls, whose free ends are located closely above the substrate. The substrate is preferably a continuous film. By measuring the reflection, the transmission, etc. of the substrate between the individual coating chambers, it becomes possible to carry out measurements within only partially completed layer systems. This yields advantages for the technical operation control of the coating process.

  • Publication number: 20080237034
    Abstract: A target containing an indium oxide and a tin oxide is used and sputtered particles from the target are transported by a forced gas flow of a sputter gas onto an organic substrate and deposited on the organic substrate while applying a DC bias voltage or an RF bias voltage to the organic substrate. The organic substrate is close to the target so that it is positively acted on by plasma. Thus, an ITO transparent conductive film having a resistivity of 10?3 ohm.cm or less is formed on the organic substrate. The formed ITO transparent conductive film has a ratio of 1:1 or more and 4:1 or less between the peak intensity of the plane and the peak intensity of the plane of the indium tin oxide in X-ray diffraction.
