Abstract
A method for forming electrically conductive paths on a substrate wherein at least a selected surface (or surfaces) of the substrate on which the paths are to be formed is made of a composition which comprises a first material, preferably a polymer material having a metal compound, preferably a metal oxide, incorporated as a filler therein. The selected surface is heated, preferably as by a high intensity laser beam, at the locations where the paths are to be formed to a temperature sufficient to reduce the metal compound to its elemental state whereby the desired electrically conductive paths are formed
Claims13
A method for forming electrically conductive regions at selected locations on at least one surface of a substrate comprising the steps of
- forming at least selected portions, which contain said selected locations, of said at least one surface of said substrate of a composition comprising a matrix of a first reducing material having a metal compound incorporated as a filler therein;
- heating said selected locations to a temperature sufficient to reduce said metal compound to its elemental metal state whereby electrically conductive regions are formed at said selected locations on said at least one surface.
A method for forming one or more electrically conductive paths on at least one surface of a substrate comprising the steps of
- forming said at least one surface of said substrate of a composition comprising a matrix of a polymer reducing material having a metal compound incorporated as a filler therein;
- heating said at least one surface of said substrate at selected locations where it is desired to form said one or more electrically conductive paths to a temperature sufficient to reduce said metal compound to its elemental metal state at said selected locations.
