Abstract:
1. A micro-fabricated biocompatible component implantable in a human body, comprising: an active element of the type selected from among the group consisting of a sensor for the measurement of a physiologic parameter, a micro-electromechanical system, and an integrated electronic circuit; a base substrate having a first face and a second face, said active element being integrated on said first face; metal pads that are biocompatible formed on said second face of said base substrate, said second face of said base substrate configured to be exposed to said body tissues or fluids when implanted in the human body; electrical connections integrated on the base substrate for connecting said metal pads to the active element; holes in the substrate for connecting said metal pads to said electrical connections in contact with said active element, said holes being hollowed through the base substrate and filled with a metal; and a lid made of silicon or quartz covering and peripherally enclosing said base substrate in a hermetic manner, said lid being a thin film layer deposited on the side of said first face of the base substrate integrating the active element, and having a raised portion such that the lid is separated from the active element to form a cavity, the cavity being free of any filler material; wherein said lid is formed on the base substrate according to a thin film packaging process; and wherein said base substrate and said lid form a biocompatible component capable of withstanding prolonged exposure to body tissues or fluids of the human body, and wherein the biocompatible component is essentially void of a metallic case for insulation between said active element and said body tissues or fluids, and void of insulating feedthroughs for electrical connection to the active element.
