ABSTRACT:
A method and apparatus for forming a low dielectric constant polymeric film on a substrate, by liquid delivery of a parylene precursor reagent, in the form of an organic solution or a neat liquid, subsequent flash vaporization of the neat liquid or organic solution, pyrolytic "cracking" of the precursor to form the reactive monomer and/or reactive radical species, and condensation and polymerization of the monomer and/or reactive radical species to form a low dielectric constant polymeric film on the substrate. The low dielectric constant polymeric film may comprise a parylene film, formed from a precursor such as [2.2]paracyclophane, an alkyl- and/or halo-substituted derivative thereof, or an analogous compound of a p-xylene derivative.
