Claim 12:
13. 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; and
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 the reaction mixture is cycled or recirculated through the reaction vessel to remove byproducts or change the composition of the reaction mixture.
