Patent ID: 7841075

Claim:
A method of making a device comprising a printed wiring board, the method comprising: providing at least one foil structure having two sides and comprising a known good, thin-film, fired-on-foil capacitor comprising a dielectric layer and a second electrode layer having a footprint; applying metal to a side of the foil structure containing the second electrode; patterning a side of the foil structure not containing the second electrode to form a plurality of first electrodes; laminating the patterned side of the foil structure to a build-up layer of a printed wiring board (PWB); patterning the side of the foil structure containing the second electrode of the fired-on-foil capacitor to form a plurality of second electrodes within the footprint of the second electrode layer, wherein the forming of the plurality of the first electrodes and of the plurality of the second electrodes forms a plurality of singulated capacitors of a certain size and pitch such that each electrodes is available to be directly attached to a terminal of an integrated circuit; and wherein the plurality of singulated capacitors lies directly under and within an area of the integrated circuit.
