Abstract:
1. An implantable device, comprising: a first electrically non-conductive substrate; a plurality of electrically conductive vias through said first electrically non-conductive substrate; a first flip-chip circuit attached to said first electrically non-conductive substrate using conductive bumps and electrically connected to at least a subset of said plurality of electrically conductive vias; a braze stop on said first electrically non-conductive substrate and along a periphery of said non-conductive substrate surrounding said plurality of conductive vias, and separating a braze joint from said plurality of conductive vias; a second flip-chip circuit electrically connected to said first flip-chip circuit; a second electrically non-conductive substrate attached to said second flip-chip circuit using conductive bumps; discrete passives attached to said second electrically non-conductive substrate; a cover bonded to said first electrically non-conductive substrate, said cover, said first electrically non-conductive substrate and said plurality of electrically conductive vias forming said implantable device; and said implantable device being hermetically sealed.
