A radiation imaging system comprising a scintillator, an imager array, and a lamination layer. Lamination layer bonds and optically couples scintillator to imager array. Lamination layer is comprised of a lamination material that is substantially free from void spaces. Radiation imaging system fabrication comprises the steps of disposing lamination layer between a light imager and a scintillator to form a subassembly. Light imager comprises imager array, an imaging plate surface and a plurality of contact pads. Additional steps include subjecting subassembly to a vacuum; heating subassembly to a bonding temperature, exerting a bonding force on subassembly, maintaining the vacuum, the bonding temperature and the bonding force until light imager is bonded to the scintillator and the lamination layer is comprised of lamination material that is substantially free from void spaces.

A method for fabricating a flexible interconnect film includes applying a resistor layer over one or both surfaces of a dielectric film; applying a metallization layer over the resistor layer with the resistor layer including a material facilitating adhesion of the dielectric film and the metallization layer; applying a capacitor dielectric layer over the metallization layer; and applying a capacitor electrode layer over the capacitor dielectric layer. The capacitor electrode layer is patterned to form a first capacitor electrode; the capacitor dielectric layer is patterned; the metallization layer is patterned to form a resistor; and the metallization layer and the resistor layer are patterned to form an inductor and a second capacitor electrode. In one embodiment, the dielectric film includes a polyimide, the resistor layer includes tantalum nitride, and the capacitor dielectric layer includes amorphous hydrogenated carbon or tantalum oxide. If the resistor and metallization layers are applied over both surfaces of the dielectric film, passive components can be fabricated on both surfaces of the dielectric film. The dielectric film can have vias therein with the resistor and metallization layers extending through the vias. A circuit chip can be attached and coupled to the passive components by metallization patterned through vias in an additional dielectric layer.
