Abstract
The present invention relates to a method for forming a conformal coating having a reactive surface. In the method, an ultrathin layer composed of a polymer having repeating units derived from unsubstituted p-xylylene, substituted p-xylylene, phenylene vinylene, phenylene ethynylene, 1,4-methylene naphthalene, 2,6-methylene naphthalene, 1,4-vinylene naphthalene, 2,6-vinylene naphthalene, 1,4-ethynylene naphthalene, 2,6-ethynylene naphthalene, combinations thereof, precursors therefor or combinations of precursors therefor, is deposited on a substrate by a thermal CVD process. The ultrathin layer is optionally exposed to a source of oxygen and then exposed to a reagent selected from ammonium hydroxide, tetramethylammonium hydroxide, ammonium sulfide, dimethyl sulfide, thioacetic acid, sodium hydrosulfide, sodium sulfide, hydrazine, acetamide and combinations thereof. The surface may be modified readily after the treatment.
