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.

For fully testing and burning-in an integrated circuit chip before it is incorporated into a high density interconnect or other standard hybrid bare chip circuit, a temporary test substrate having pins extending therethrough holds the chip within a cavity. Chip pads are electrically connected with the pins to create a package that can be tested using commercially available testing and burn-in devices. After testing, the chip is retrieved from the test structure undamaged. In using HDI techniques to interconnect the chip with the pins, metal-filled vias in a polymer layer overlying the temporary test substrate electrically connect the chip to the pins through a metal interconnect pattern on the polymer layer. In another embodiment, the chip is interconnected with the pins through wire bonds. Metal-filled vias pass through an insulative coating on the chip and make electrical contact with the chip pad. A temporary buffer pad connected to a respective via and offset from the chip pad connected to that via comprises a wire-bonding site.
