  • Publication number: 20110157775
    Abstract: A decoupling device includes a lead frame, a capacitor unit, a metal layer, and a high dielectric organic-inorganic composite material layer. The lead frame includes a cathode terminal portion and an anode terminal portion. The capacitor unit is disposed on the lead frame. The capacitor unit includes a cathode portion, an anode portion, and an insulation portion located between the cathode portion and the anode portion. The cathode portion is electrically connected to the cathode terminal portion, and the anode portion is electrically connected to the anode terminal portion. The high dielectric organic-inorganic composite material layer is connected to the capacitor unit in parallel via the metal layer.

  • Patent number: 7894178
    Abstract: A through hole capacitor at least including a substrate, an anode layer, a dielectric layer, a first cathode layer, and a second cathode layer is provided. The substrate has a plurality of through holes. The anode layer is disposed on the inner surface of at least one through hole, and the surface of the anode layer is a porous structure. The dielectric layer is disposed on the porous structure of the anode layer. The first cathode layer covers a surface of the dielectric layer. The second cathode layer covers a surface of the first cathode layer, and the conductivity of the second cathode layer is greater than that of the first cathode layer. The through hole capacitor can be used for impedance control, as the cathode layers of the through hole are used for signal transmission.
