Abstract:
1. A method for fabricating a flexible thin-film substrate for attachment of a device to be implanted, the method comprising: depositing a first thin-film layer on a silicon-wafer to form a bottom thin-film layer; depositing a metal to the bottom thin-film layer to form an electrical connection; depositing a second thin-film layer adjacent to the metal to form a top thin-film layer and to thereby form a thin-film metal thin-film sandwich; providing a mask adjacent to the second thin-film layer; directing an etching beam onto the mask to fabricate the flexible thin-film for attachment of the device, detaching the silicon-wafer from the flexible thin-film substrate and attaching the device, wherein the device is an integrated circuit chip (IC Chip), which electrically connects the flexible thin-film substrate to the IC Chip, and wherein the flexible thin-film substrate and device are encapsulated for biocompatibility.
