Process of making components for electronic and optical devices using laser processing on a patterned conductive film

A process of making an electrical component, an optical component or a combined electrical and optical component, said process comprising:

• a) applying one or more coatings of electrically conductive material to a substrate having a first side and a second side, said one or more coatings of electrically conductive material being applied to at least the first side of said substrate;
• b) using a laser to remove a portion of said electrically conductive material to form a pattern of electrically conductive material electrodes on said substrate;
• c) applying one or more chemical coatings in the form of a continuous film over said patterned electrical conductive material to form a coated substrate, wherein
• (i) said patterned electrical conductive material comprises a material selected from the group consisting of poly(3,4-ethylenedioxythiophene), poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, poly(pyrrole), polycarbazoles, polyindoles, polyazepines, Cr, Mo, Ti, Sc, Ni, V, Hf, W, Nb, Au, Ag, Cu, and Pt and mixtures thereof;
• (ii) said one or more chemical coatings each independently comprising a transition metal and an element selected from the group consisting of hydrogen, carbon, nitrogen, oxygen, sulfur, selenium, phosphorous and mixtures thereof, said one or more chemical coatings each independently comprising at least one of an amorphous, nanocrystalline, microcrystalline or crystalline region;
• and
• d) pattern illumination-based annealing said coated substrate, said pattern illumination-based annealing comprising using one or more lasers and/or lamps to achieve at least one of a chemical change or change in crystallization in at least a portion of at least one of said one or more chemical coatings on at least one side of said substrate, wherein said chemical change or change in crystallization changes said at least said portion to a semiconducting material, which semiconducting material is in contact with the underlying patterned electrical conductive material that was formed on said substrate.
