Claim 16:
17. A method for deposition of patterns on surfaces by directed energy deposition of carbon, comprising the steps of:
selecting a pattern for deposition on a surface of a solid substrate;
providing a reaction mixture comprised of a deposit precursor, a directed electromagnetic radiation apparatus, said solid substrate, and a reaction vessel;
placing the substrate and reaction mixture in the form of a gas or liquid, which is absorbed or adsorbed to the substrate, into the reaction vessel;
selectively sending directed electromagnetic radiation towards the adsorbed or absorbed reaction mixture in the reaction vessel with the directed energy emission apparatus;
causing a polymerization and/or decomposition reaction within the reaction mixture adjacent to a point of incidence of the directed energy emission on the surface of the substrate to produce a nonhomogeneous or nonuniform deposit layer having the selected pattern,
wherein directed energy is either a focused or collimated beam or a laser beam,
wherein the reaction mixture is comprised of a deposit precursor, which can be decomposed to form a deposit of carbon, and
wherein the reaction mixture is comprised of trichlorobenzene.
