A hermetically sealed housing encloses an inert gas atmosphere, and an electrical interconnect has at least one electrically conductive signal trace embedded onto a liquid crystal polymer body to extend from an interior of the housing to an exterior of the housing. The platform comprises a platform shelf and a plurality of spaced-apart platform supports integral with the platform shelf and interfused with surfaces of the base. At least a portion of the device is coated with a coating that at least partially inhibits adhesion of organic molecules to the device following implantation. A central substrate of lower doping concentration may be provided to provide a resistor in series below the capacitor bottom plate. In one embodiment, the denture base snap-fits onto the support bar.
