  • Patent number: 9318266
    Abstract: A multi-layered capacitor includes three or more capacitor layers. A first layer includes a first DC-biased, tunable capacitor. A second layer, acoustically coupled to the first layer, includes a second DC-biased, tunable capacitor. A third layer, acoustically coupled to the second layer, includes a third DC-biased, tunable capacitor. Each dielectric of the first, second, and third capacitors has a resonance of about the same frequency, within 5%, and inner electrodes of the first, second, and third capacitors have a resonance of about the same frequency, within 5%. The resonance of each layer is a function of at least thickness, density, and material. The first, second, and third layers are biased to generate destructive acoustic interference, and the multi-layer capacitor is operable at frequencies greater than 0.1 GHz.

  • Publication number: 20140370673
    Abstract: An electronic component is provided on a substrate. A thin-film capacitor is attached to the substrate, the thin-film capacitor includes a pyrochlore or perovskite dielectric layer between a plurality of electrode layers, the electrode layers being formed from a conductive thin-film material. A reactive barrier layer is deposited over the thin-film capacitor. The reactive barrier layer includes an oxide having an element with more than one valence state, wherein the element with more than one valence state has a molar ratio of the molar amount of the element that is in its highest valence state to its total molar amount in the barrier of 50% to 100%. Optionally layers of other materials may intervene between the capacitor and reactive barrier layer. The reactive barrier layer may be paraelectric and the electronic component may be a tunable capacitor.
