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
