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.

Method of patterning a metal on a transparent conductor

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 via extending from the second major surface to the first major surface. The conductive layer includes electrically separated first and second portions configured to support and electrically connect a light emitting semi-conductor device to the conductive layer.

Flexible light emitting semiconductor device

Provided is a flexible light emitting semiconductor device, such as an LED device, that includes a flexible dielectric layer having first and second major surfaces with a conductive layer on the first major surface and at least one cavity in the first major surface with a conductive layer in the cavity that supports a light emitting semiconductor device. The conductive layer in the cavity is electrically isolated from the second major surface of the dielectric layer.

Flexible LED device for thermal management

An article includes a flexible polymeric dielectric layer having first and second major surfaces. The first major surface has a conductive layer thereon and at least one cavity therein. The at least one cavity contains a conductive material including electrically separated first and second portions supporting and electrically connecting a light emitting semiconductor device to the conductive layer on the first major surface.

Flexible LED device with wire bond free die

A double ITO structure, containing sequential layers of indium tin oxide (ITO), silicon dioxide (SiO) (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.
