Patent ID: 8391017

Claim:
A method of making a semiconductor package comprising: providing a fired-on-foil thin film capacitor having a nickel foil, a first copper layer, and a thin-film dielectric between and in contact with said nickel foil and said first copper layer; patterning said first copper layer to form a first electrode of said fired-on-foil capacitor and a plurality of pads separated from and electrically isolated from the first electrode; providing build-up material and a PWB core having a first surface; positioning the build-up material between the patterned first copper layer and the first surface of the PWB core; attaching the patterned first copper layer of the thin-film capacitor to said PWB core by way of said build-up material; forming at least three microvias through each of the nickel foil, the thin-film dielectric, and the first copper layer of said fired-on foil capacitor, wherein two of said at least three microvias pass through different of the plurality of pads patterned from said first copper layer and one of said at least three microvias passes through the first electrode patterned from said first copper layer; depositing a second copper layer onto the nickel foil and into the at least three microvias, said deposited second copper layer contacting each of the nickel foil, the thin film dielectric, and the copper first layer; and depositing a third copper layer onto the second copper layer deposited on the nickel foil and patterning said third copper layer, said second copper layer and said nickel foil to form a plurality of nickel-copper pads and a nickel-copper second electrode, wherein the plurality of nickel-copper pads are electrically isolated from each other and are electrically isolated from the nickel-copper second electrode, and wherein at least two of said nickel-copper pads are each aligned with and electrically connected to one of the at least three microvias, and wherein said nickel-copper second electrode is aligned with and electrically connected to another one of the at least three microvias.
