Embodiment

[0114] In this example, a polycarbonate conduit channel with a square cross-section was formed as an integral part of a polycarbonate 100 micron sheet. A conductive transparent form of polythiophene was applied inside the square conduit channel to form a transparent conductive sheet. Terminate square conduit at a common point. The common point is 1 micron below the top surface of the conduit channel, which provides a vertically offset termination of the transparent conductive conduit. This example will illustrate the conductive and transmissive properties of a polymer sheet comprising a conductive transparent polymer and illustrate the use of terminations.

[0115] Square conduits were fabricated by casting molten polycarbonate onto a heated roll containing the opposite side of the square groove pattern. Square groove patterned rolls were fabricated by precision machining a negative mold of the square groove pattern into the smooth steel roll surface using a wire EDM cutting...

Abstract

The present invention discloses an article comprising a polymer sheet, wherein the polymer sheet contains a plurality of integral polymeric conduit channels comprising a transparent conductive material in which two or more such channels terminate.

Description

field of invention [0001] The present invention relates to a transparent patterned conductive sheet comprising below grade conductive channels aligned to form termination points. Background of the invention [0002] As electronic devices become smaller, the requirement for precise electrical connections at extremely fine pitches continues to increase. For example, semiconductors, such as integrated circuits, are formed on a wafer, which is then diced into small dice or chips that can be individually mounted on a substrate. Typically, the substrate has fine conductive circuit lines, and electrical and thermal contact must be made between the substrate and the chip. As electronic equipment such as computers, tape players, televisions, telephones, and other devices become smaller, thinner, and lighter, there is a growing need for electrical connections between semiconductors and between semiconductors and substrates or between flexible circuits and hard printed circuits. The ...
