Parylene deposition is a method for depositing parylene, a thin, transparent polymer coating that is conformal, usually pinhole free, has high dielectric strength, high surface and volume resistivity, and resists moisture, acids, alkalis, petroleum products and solvents. Parylene is also “body safe” which means it can be used to protect medical devices and implantable electronics.

Equipment

SCS PDS 2035CR

Main article: SCS PDS 2035CR

Materials

  • Parylene type C only

Method of operation

A solid, granular raw material, called dimer, is heated under under vacuum and vaporized into a dimeric gas. The gas is then pyrolized to cleave the dimer to its monomeric form. In the room temperature deposition chamber, the monomer gas deposits on all surfaces as a thin, transparent polymer film.
