Patent ID: 6887578

Claim:
A method for forming a copolymer thin film on surface of a structure, comprising the steps of: exposing at least two monomer gasses selected independently from the group consisting of organosilicons and halocarbons to a source of heat having a temperature sufficient to pyrolyze the monomer gasses, the monomer gases selected to produce upon pyrolysis sources of reactive species that include polymerizable species and that selectively promote copolymerization, the reactive species sources being in the vicinity of a structure surface on which a copolymer thin film is to be formed; wherein halocarbons are selected from the group consisting of hexafluoropropylene oxide, tetrafluoroethylene, hexafluorocyclopropane, octafluorocyclobutane, perfluorooctanesulfonyl fluoride, octafluoropropane, trifluoromethane, difluoromethane, difluorodichloromethane, difluorodibromomethane, difluorobromomethane, difluorochloromethane, trifluorochloromethane, tetrafluorocyclonronane, tetrachlorodifluorocyclopropane, trichlorotrifluoroethane, and dichlorotetrafluorocyclopropane; and maintaining the structure surface at a substantially lower temperature an that of the heat source to induce deposition and polymerization of the reactive species on the structure surface.
