  • Patent number: 8587922
    Abstract: In a feed-through capacitor, a conduction unit having a plurality of conduction inner electrodes can fully secure a tolerable level of DC. A capacitor unit is formed on the mount surface side in a capacitor body, so that high-frequency noise components can be removed by the capacitor unit before reaching the conduction unit. The distance between the grounding inner electrode located closest to the conduction unit and the conduction inner electrode in the conduction unit is greater than that between the signal inner electrode and grounding inner electrode in the capacitor unit. This enhances the impedance between the capacitor unit and the conduction unit, so as to inhibit the high-frequency noise components from flowing into the conduction unit.

  • Publication number: 20130258550
    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.

    Abstract: Technologies are generally described for a nanocomposite polymer dielectric that may incorporate two types of nanoparticles and a polymer. One of the two types of nanoparticle may be a first, smaller nanoparticle, that may occupy spaces between larger second nanoparticles. Another of the two types of nanoparticle may be the second, larger, “high-?” nanoparticle, which supports the overall dielectric constant of the material. In an applied electric field, the first, smaller nanoparticle may redistribute local charge to homogenize electric fields in the dielectric material, tending to avoid the development of “hot spots”. Such a two-nanoparticle nanocomposite dielectric material may provide increased dielectric breakdown strength and voltage endurance in comparison with a nanoparticle dielectric which only contains a single type of “high-?” nanoparticle.

    Abstract: The use of a monolayer or partial monolayer sequencing process, such as atomic layer deposition, to form a dielectric layer of hafnium oxide doped with dysprosium and a method of fabricating such a combination produces a reliable structure for use in a variety of electronic devices. Forming the dielectric structure can include depositing hafnium oxide onto a substrate surface using precursor chemicals, followed by depositing dysprosium oxide onto the substrate using precursor chemicals, and repeating to form a thin laminate structure. A dielectric layer of dysprosium doped hafnium oxide may be used as the gate insulator of a MOSFET, as a capacitor dielectric in a DRAM, as a tunnel gate insulator in flash memories, or as a dielectric in NROM devices, because the high dielectric constant (high-k) of the film provides the functionality of a thinner silicon dioxide film, and because the reduced leakage current of the dielectric layer when the percentage of dysprosium doping is optimized improves memory function.

According to this ceramic capacitor, since the internal electrode dimensions can be easily controlled like this, dimensional control of internal electrode spacing can also be easily carried out.
