Abstract
Methods of manufacturing a biocompatible, hermetic feedthrough monolithically integrated with a biocompatible ribbon cable are described, as well as the resulting devices themselves. The hermetic feedthrough is created by placing glass over a mold of doped silicon or other material with a higher melting temperature than the glass and heating it to reflow the glass into the mold. The glass is then ground or otherwise removed to reveal a flat surface, and tiny pillars that were in the mold are isolated in the glass to form electrically conductive vias. The flat surface is used to cast a polymer and build up a ribbon cable, photolithographically or otherwise, that is monolithically attached to the vias.
