Abstract:
An apparatus for fabricating a multi-layer structure over a surface of a substrate, comprising:a holder for a supported mask, wherein the mask defines a portion of a layer of said multi-layer structure that is to receive a material provided by electrodeposition, and wherein, prior to and during said electrodeposition, said supported mask and said surface of said substrate are urged together; a movable stage for accurately positioning said substrate relative to said mask and thereafter urging the supported mask against the substrate; means for providing an electrodeposition fluid; an electrical circuit coupling said substrate as an electrode for electrodeposition; and means for repeatedly controlling the movable stage and the electrical circuit during the formation of each of a plurality of layers of the multi-layer structure, wherein material deposited in association with each successive layer is at least in part deposited onto material deposited in association with formation of a previous layer.
