Abstract

We report on the development of a non-hermetic micropackage technology that employs multiple layers of polydimethylsiloxane (PDMS), epoxy, and parylene-C thin films for conformai coating of chronic biomedical implantable systems with laboratory testing results in saline bath at 85°C, achieving very long micropackaging lifetime (up to ∼2-5 years). By combining experiments of material characterization and qualitative analysis of the observations, we explain the measured long lifetimes of the micropackages (projected equivalent of ∼2-5 years) using these non-hermetic coating materials and composites.
