1. A method for the deposition of thin film comprising:
- (a) ionizing at least one vaporized non-deposition material to form a flux comprising ions and neutral fragments of such vaporized non-deposition material;
(b) extracting from said flux a primary energetic ion beam consisting essentially of ions of vaporized non-deposition material;
(c) accelerating said primary energetic ion beam of vaporized non-deposition material to an energy level of at least 1 Kev and directing said primary energetic ion beam into a deposition chamber containing a substrate selected from the group consisting of metals, glass, and polymers, said deposition chamber containing also a vaporized deposition material comprising at least one hydrocarbon monomer and an electric field directed toward said substrate;
(d) passing said primary energetic ion beam of non-deposition material through said vaporized deposition material whereby such vaporized deposition material is ionized by interaction with said primary energetic ion beam of non-deposition material, said ions of vaporized deposition material being secondary ions which, under the influence of the aforementioned electric field, are energized and directed toward the surface of said substrate; and
(e) coimpinging said primary energetic ion beam of non-deposition material and secondary ions of vaporized deposition material against a surface of said substrate for a time sufficient to implant at least a portion of said ions of vaporized deposition material into said substrate and to form a thin film comprising a hydrocarbon polymer in and on such substrate, such film being merged into and with ions of vaporized deposition material and the atoms of said substrate.

Abstract
Thin film coatings comprising hydrocarbon polymers are deposited on and merged into a substrate by causing secondary ionically activated and electric field energized atomic or molecular ionic species including hydrocarbon species to be directed to a substrate in conjunction with an ion beam of primary energetic ions.
