  • Publication number: 20100117488
    Abstract: An electrical generator includes a substrate, a semiconductor piezoelectric structure having a first end and an opposite second end disposed adjacent to the substrate, a first conductive contact and a second conductive contact. The structure bends when a force is applied adjacent to the first end, thereby causing an electrical potential difference to exist between a first side and a second side of the structure. The first conductive contact is in electrical communication with the first end and includes a material that creates a Schottky barrier between a portion of the first end of the structure and the first conductive contact. The first conductive contact is also disposed relative to the structure in a position so that the Schottky barrier is forward biased when the structure is deformed, thereby allowing current to flow from the first conductive contact into the first end.

  • Patent number: 7576440
    Abstract: A semiconductor chip comprises a semiconductor substrate having integrated circuits formed on a cell region and a peripheral circuit region adjacent to each other. A bond pad-wiring pattern is formed on the semiconductor substrate. A pad-rearrangement pattern is electrically connected to the bond pad-wiring pattern. The pad-rearrangement pattern includes a bond pad disposed over at least a part of the cell region. The bond pad-wiring pattern is formed substantially in a center region of the semiconductor substrate. Thus, with the embodiments of the present invention, the overall chip size can thereby be substantially reduced and an MCP can be fabricated without the problems mentioned above.

  • Patent number: 7465951
    Abstract: The invention provides for a write-once nonvolatile memory array, the memory cells comprising a phase change material, such as a chalcogenide. Phase change is achieved in chalcogenide memories by thermal means. The initial, unprogrammed state of each memory cell is a crystalline, low-resistance state, while the programmed state is an amorphous, high-resistance state. Optimizing the circuitry for a write-only memory array, the wordlines or bitlines can be long, with at least 256 cells on a wordline or bitline, and in some embodiments, having thousands of cells on a wordline or bitline. In a preferred embodiment, such an array can be a monolithic three dimensional memory array comprising stacked memory levels.

    Abstract: The difficulty of miniaturization of large-scale integrated circuits in electric devices based on the conventional techniques involving three-dimensional device structures or the introduction of novel materials is solved. Wires 2 and 3 are disposed to intersect one another in midair in a matrix. The ends of the wires 2 and 3 in midair are designed to be in direct contact with the insides of a package which contains a semiconductor device so that electrical connection and/or physical support can be acquired. Cross point 1 where wires 2 and 3 are in contact with each other is a region which has current switching function similar to the function of a channel of a common MOSFET. Cross point 1 is a region where base wire 2 functioning as a substrate and gate electrode wire 3 functioning as a control electrode (gate electrode) intersect in contact with one another, or a region where base wire 2 and a lead wire 4 overlap.
