METHOD OF PATTERNING ELECTRICALLY-CONDUCTIVE FILM ON FLEXIBLE SUBSTRATES

摘要

A method of patterning an electrically-conductive film is performed by providing a flexible substrate that carries the electrically-conductive film thereon to form a combined layer. The combined layer is then bent about a radius of curvature, so as to impart a stress on the brittle conductive film along the axis of curvature of the curved surface. The application of the stress to the conductive film results in the formation of crack lines that are substantially perpendicular to the direction to which the substrate and conductive film are bent. The crack lines serve to define and electrically isolate conductive sections therebetween that can be utilized as electrodes and address lines in electronic devices.
