Patent ID: 7934314

Claim:
A method for forming a conductive film structure, comprising: providing a flexible insulating substrate; forming a conductive film overlying the flexible insulating substrate; patterning the conductive film to form a plurality of micro-wires overlying the flexible insulating substrate, wherein the micro-wires are extended substantially parallel to each other; forming an insulating layer overlying the flexible insulating substrate and the micro-wires, wherein the insulating layer comprises a polymer layer with an adhesive layer added thereon or an adhesive polymer layer; winding or folding the flexible insulating substrate along an axis substantially parallel to an extending direction of the micro-wires to form a conducting lump; and depositing a conductive material overlying two opposite ends of the micro-wires by electrochemical deposition to elongate the micro-wires such that the opposite ends thereof are exposed or protrude from the conducting lump.
