  • Thin-film capacitor structures embedded in semiconductor packages and methods of making
    Patent number: 8391017
    Abstract: Provided are semiconductor packages comprising at least one thin-film capacitor attached to a printed wiring board core through build-up layers, wherein a first electrode of the thin-film capacitor comprises a thin nickel foil, a second electrode of the thin-film capacitor comprises a copper electrode, and a copper layer is formed on the nickel foil. The interconnections between the thin-film capacitor and the semiconductor device provide a low inductance path to transfer charge to and from the semiconductor device. Also provided are methods for fabricating such semiconductor packages.
    Type: Grant
    Filed: April 20, 2010
    Date of Patent: March 5, 2013
    Assignee: Georgia Tech Research Corporation
    Inventors: David Ross McGregor, Cheong-Wo Hunter Chan, Lynne E. Dellis, Fuhan Liu, Deepukumar M. Nair, Venkatesh Sundaram
