  • Patent number: 7960226
    Abstract: On-chip decoupling capacitor structures, and methods of fabricating such decoupling capacitors are disclosed. On-chip decoupling capacitors help to reduce or prevent L di/dt voltage droop on the power grid for high surge current conditions. The inclusion of one or more decoupling capacitors on a chip, in close proximity to the power grid conductors reduces parasitic inductance and thereby provides improved decoupling performance with respect to high frequency noise. In one embodiment of the present invention, a capacitor stack structure is inserted between metal interconnect layers. Such a capacitor stack may consist of a bottom electrode/barrier; a thin dielectric material having a high dielectric constant; and a top electrode/barrier. In an alternative embodiment, the bottom electrode and/or bottom metal interconnect layer have three dimensional texture to increase the surface area of the capacitor.

  • Publication number: 20060286771
    Abstract: A layer transfer technique in which a portion of a donor wafer is doped with positively charged hydrogen ions and positively charged helium ions before it is bonded to a portion of a handle wafer. Furthermore, the bonded wafers are annealed at one of two annealing temperatures, which determines whether the wafers are separated using a thermal cleave or a mechanical cleave process.
