  • Publication number: 20090002919
    Abstract: An organic dielectric material comprises a branched and/or hyperbranched macromolecule having delocalized electrons. Such macro-molecular organic material systems have desirable delocalized charge and optionally one or more micro-crystalline regions. Organic dielectric materials include, for example, branched polyanilines and phthalocyanines. Delocalized excitations within the macromolecular framework of the organic dielectric material may be used in various applications, such as light harvesting, nonlinear optical, quantum optical, and electronic applications, e.g., capacitors. Electrical devices may comprise such dielectric materials, including capacitors that have very high energy density, storage, and transfer. Also provided are methods of preparing such materials.

  • Patent number: 7471500
    Abstract: A multi-segment parallel wire capacitor includes substantially identical multiple capacitor segments fabricated on a semiconductor substrate. Each segment comprises at least first and second interleaved metal finger formed in a first metal layer above the substrate and third and fourth interleaved metal fingers formed in a second metal layer. The first and fourth sets are connected together to form one plate of the capacitor and the second and third sets are connected to form a second plate. The multiple capacitor segments are arranged in a matrix having M rows and N columns. The multiple capacitor segments are inter-connected in such a manner that the capacitor segments in each column of the matrix are connected in parallel. First and second metal lines selectively connect the plates of the different capacitor segments in the first and last rows and serve as the two opposite terminals of the multi-segment parallel wire capacitor.

  • Patent number: 7468881
    Abstract: A multilayer electronic component has: a first capacitive electrode layer of a rectangular shape on which four capacitive electrode portions are formed at four comers; and a ground electrode layer which is laid on the first capacitive electrode layer and on which a ground electrode is formed so as to be arranged as superposed over the four capacitive electrode portions. The four capacitive electrode portions are equidistant from a first facing edge pair of the first capacitive electrode layer and equidistant from a second facing edge pair different from the first edge pair. This configuration equalizes distributions of electric fields established between the respective capacitive electrode portions and the ground electrode, which realizes uniformization of the capacitances in the four respective capacitive electrode portions.

  • Patent number: 7466538
    Abstract: A highly reliable multilayer ceramic electronic device is obtained while preventing crack defects generated in a ceramic laminate by application of a heat shock in a mounting step or the like. The multilayer ceramic electronic device is constructed such that the average value of continuities of internal electrodes located in two regions (f) is lower by 5% to 20% inclusive than the average value of continuities of internal electrodes located in the central portion in a lamination direction. The two regions (f) are the regions from the topmost internal electrode and the bottommost internal electrode located in the lamination direction to the inside, respectively, within 10% of the distance (d) therebetween. Continuity is defined by (X?Y)/X in which X is the length of a cross section of an internal electrode in one direction and Y indicates the sum of gaps (g) formed by pores in the cross section of the internal electrode.

  • Patent number: 7466536
    Abstract: An electrical-energy-storage unit (EESU) has as a basis material a high-permittivity composition-modified barium titanate ceramic powder. This powder is single coated with aluminum oxide and then immersed in a matrix of poly(ethylene terephthalate) (PET) plastic for use in screen-printing systems. The ink that is used to process the powders via screen-printing is based on a nitrocellulose resin that provide a binder burnout, sintering, and hot isostatic pressing temperatures that are allowed by the PET plastic. These lower temperatures that are in the range of 40° C. to 150° C. also allows aluminum powder to be used for the electrode material. The components of the EESU are manufactured with the use of conventional ceramic and plastic fabrication techniques which include screen printing alternating multilayers of aluminum electrodes and high-permittivity composition-modified barium titanate powder, sintering to a closed-pore porous body, followed by hot-isostatic pressing to a void-free body.

  • Patent number: 7463475
    Abstract: A multilayer electronic component having a ceramic substrate and a resin layer mounted on a mounting substrate. Recess portions are formed at an outside-facing major surface side of the resin layer. In the resin layer, columnar conductors are disposed so that axis line directions thereof are aligned in a thickness direction of the resin layer. End portions of the columnar conductors are located inside the recess portions further from opening faces thereof and have end surfaces exposed in the recess portions. When a multilayer electronic component is mounted on a mounting substrate, solder is provided on the end surfaces of the columnar conductors in the recess portions. The thickness of solder used in the above mounting does not interfere with a reduction in size and height of an electronic device that includes the above multilayer electronic component.
