Parylene Coating Service

CMC provides access to parylene coating service through Advanced Coating. A thin film of parylene-c polymer can be conformally coated onto various devices, substrates, and circuit boards to provide protection against certain harsh environment conditions or to improve biocompatibility.

Applications

  • Protection of microsystem components or circuit boards against moisture, chemical corrosion, and dielectric breakdown
  • Biocompatible coating of CMOS/MEMS bio- or chemosensors and other biomedical device

Overview

  • Conformal coating is applied by a vapor phase deposition process
  • Thickness ranges from a few micrometers to tens of micrometers
  • Coating works better on a textured surface than a highly polished surface
  • Selective coating is available subject to device dimensions
  • Parylene is well accepted in medical device industry due to its good biocompatibility and low cytotoxicity

Cost 

TBD with Prototyping Subscription
