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.

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.

Abstract: A flexible polymeric dielectric layer has first and second major surfaces. The first major surface has a conductive layer thereon. The dielectric layer has at least one cavity extending from the second major surface toward the first major surface. The conductive layer includes electrically separated first and second portions configured to support and electrically connect a light emitting semiconductor device to the conductive layer.
