Coating Spotlight: SCS ALD+Parylene Multilayer Coatings

A newer technology at SCS, ALD+Parylene combines atomic layer deposition (ALD) coatings with Parylene  to form an enhanced multilayer coating that offers increased barrier properties to protect devices in extreme environments. Multilayer coatings are stacked structures that alternate different layers of organic and inorganic thin films. ALD films can be made of numerous inorganic materials, including aluminum oxide, titanium oxide and hafnium oxide.
