Abstract:
A parylene film growth system for forming a parylene film on a substrate, said system comprising:a supply of a precursor comprising a parylene source reagent;a flash vaporizer and pyrolytic cracking unit for flash vaporizing the precursor to form flash vaporized precursor and pyrolytically cracking the flash vaporized precursor to yield a precursor vapor including a parylene source monomer and/or reactive radical species;means for flowing the precursor from the supply thereof to the flash vaporizer and pyrolytic cracking unit, for flash vaporization therein to form the flash vaporized precursor and pyrolytic cracking of the flash vaporized precursor to form precursor vapor including the parylene source monomer and/or reactive radical species;a contacting chamber constructed to hold a substrate therein for contacting with the precursor vapor; andmeans for flowing the precursor vapor from the flash vaporizer and pyrolytic cracking unit to the contacting chamber for contact of the precursor vapor with the substrate under conditions producing condensation of the parylene-source monomer and/or reactive radical species to form a polymeric film of parylene on the substrate.
