Abstract:
A method of making an infrared sensing integrated circuit, comprising:fabricating a substrate which includes a plurality of electrically conductive elements, and including a plurality of thermally sensitive elements which are each disposed over a respective one of said electrically conductive elements; andforming an infrared absorptive, conductive-polymer coating on said substrate, above all of said thermally sensitive elements by:generating a low-melting-point electrical conductor vapor;generating a polymer vapor with a pyrolysis furnace;mixing said electrical conductor vapor and said polymer vapor in a first vacuum chamber;exposing said substrate to said vapors to allow deposition of said vapors on said substrate; andashing said conductive-polymer coating after said exposing said substrate to said vapors, in order to facilitate infrared absorption by said conductive-polymer layer.
