Claim Text:
1. A method of making an implantable device comprising: forming a substrate including an electrically non-conductive body and electrically conductive feedthroughs through the electrically non-conductive body; forming first bond pads on a first side of the substrate electrically connected to the feedthroughs; attaching electronics to a second side of the of the substrate and electrically connecting the electronics to the feedthroughs; attaching a cover to the second side of the substrate forming a hermetic package enclosing the electronics; forming a flexible circuit having a first polymer layer, conductive traces on the first polymer layer, and a second polymer layer on the conductive traces, the first polymer layer defining voids connecting second bond pads to the conductive traces; and aligning the first bond pads with the second bond pads and bonding the flexible circuit to the substrate.
