  • Patent number: 10237985
    Abstract: The present disclosure provides a method to provide a conductive bus bar on a patterned transparent conductor, such as ITO traces used for touch screen manufacturing. The method can be a cheaper and a more convenient technique to pattern a conductive metal or metal alloy, such as copper, silver, or a copper/silver/titanium alloy, on ITO electrodes in a roll-to-roll process.
    Type: Grant

  • Patent number: 9023229
    Abstract: A double ITO structure, containing sequential layers of indium tin oxide (ITO), silicon dioxide (SiO2) (which may include a dopant material) and ITO, is selectively protected by a patterned photo-resist mask. The sequential layers are etched together in a single etching step using an etchant composition which is an acidic solution containing a transition metal chloride and hydrochloric acid (HCl). Thus, the double ITO structure is etched using a substantially fluoride-free etchant composition.
