Abstract:
A microelectronic substrate having a substrate core with at least one plated through hole extending therethrough, wherein the plated through hole includes a fluorescent conductive fill material. In one embodiment, the plated through hole may comprise a hole defined to extend from a first surface to an opposing second surface of the substrate core, wherein a conductive material layer is formed on a sidewall(s) of the substrate core hole and a conductive fill material, having a fluorescent component, is disposed to fill the remaining substrate core hole after forming the conductive material layer. In another embodiment of the present description, the fluorescent conductive fill material is used for the detection of defects.
Abstract:
The present invention relates to a pattern-forming composition used to form a conductive circuit pattern. The pattern-forming composition comprises Cu powders, a solder for electrically coupling the Cu powders, a polymer resin, a curing agent and a reductant. According to the present invention, a circuit pattern having superior conductivity can be formed at low cost.
Abstract:
Discloses herein is a patterned transparent conductive electrode, comprises a substrate and a substantial single conductive layer on top of the substrate. The single conductive layer comprises a first region having a network of metal nanowires; and a second region, having a metal/metal oxide nanowire in a core shell structure.
Abstract:
An article includes a multilayer structure, such as, e.g., a touch sensor, having two opposing sides and comprising a central polymeric UV transparent substrate, a transparent conductive layer on each of the two major opposing surfaces of the polymeric substrate, a metallic conductive layer on each transparent conductive layer, and a patterned photoimaging mask on each metallic conductive layer.
