  • Publication number: 20090273058
    Abstract: Electrical components for microelectronic devices and methods for forming electrical components. One particular embodiment of such a method comprises depositing an underlying layer onto a workpiece, and forming a conductive layer on the underlying layer. The method can continue by disposing a dielectric layer on the conductive layer. The underlying layer is a material that causes the dielectric layer to have a higher dielectric constant than without the underlying layer being present under the conductive layer. For example, the underlying layer can impart a structure or another property to the film stack that causes an otherwise amorphous dielectric layer to crystallize without having to undergo a separate high temperature annealing process after disposing the dielectric layer onto the conductive layer. Several examples of this method are expected to be very useful for forming dielectric layers with high dielectric constants because they avoid using a separate high temperature annealing process.

  • Publication number: 20090195961
    Abstract: Quantum Batteries (super capacitors) which by a new quantum effect “virtual photon resonance” can store electrical energy as a pure electrical battery in ranges up to 15 MJ/kg and more. The battery is basically a capacitor composed of insulating matrix material with either dispersed nanocrystal particles of Rutile TiO2 or alternating layers of Rutile crystal TiO2 deposited by Vapor Deposition Process. After reaching the resonance conditions (electrostatic field has suitable 1) strength and 2) energy content) the capacitor becomes a constant voltage battery and takes up additional energy by Dirac current pulses at very fast rates. Thereby the Rutile crystal (semiconductor) changes its state from an insulator to becoming conductive. The battery can be built flat or wound. Voltage from a few to kVolts and top capacities are only limited to mechanical constraints. Due to the nearly zero source resistance the battery loads and discharges at constant voltage and at extremely high rates.

  • Patent number: 7567426
    Abstract: Disclosed herein is a polymer-ceramic dielectric composition. The dielectric composition comprises a polymer and a ceramic dispersed in the polymer wherein the ceramic is composed of a material having a perovskite structure represented by ABO3 and a metal oxide dopant and has an electrically charged surface. According to the dielectric composition, the surface of the ceramic is electrically charged to induce space-charge polarization (or interfacial polarization) at the polymer/ceramic interface, resulting in an increase in dielectric constant. Since the dielectric composition has a high dielectric constant particularly in a low-frequency range, it can be suitably used to produce decoupling capacitors.
