Biocompatible ALD barrier coatings for medical devices

Atomic layer deposition (ALD) is widely in use for depositing a variety of materials, such as metal oxides, metal nitrides and metals, in a conformal and defect-free form at low temperatures on high aspect-ratio substrates. These advantages make ALD uniquely powerful method for applications where sensitive substrate materials combine with extreme demands on coating quality and temperature/chemical resistance, such as those often seen in the medical applications
