Parylene also has a low dissipation factor, and high surface and volume resistivity that remain virtually constant with changes in temperature. Other raw materials, such as the cleaning materials and adhesion promotion mediums, also factor into the materials costs for parylene. NOTE: Insert the boat only far enough to close the vaporizer door. Apply the MicroSoap to: the interior of the coating chamber; The plasma deposition of the parylene-C film was carried out using a custom-built parylene coater from Femto Science Co.
