  • Patent number: 7852189
    Abstract: A spiral inductor is disposed above a substrate that includes two different materials. A dielectric film is the first material that provides structural integrity for the substrate. A second dielectric is the second material that provides a low dielectric-constant (low-K) material closest to the spiral inductor coil. A process of forming the spiral inductor includes patterning the substrate to allow a recess as a receptacle for the second dielectric, followed by forming the spiral inductor mostly above the second dielectric.
    Type: Grant

  • Patent number: 7535080
    Abstract: A method to reduce parasitic mutual capacitances in embedded passives. A first capacitor is formed by first and second electrodes embedding a dielectric layer. A second capacitor is formed by third and fourth electrodes embedding the dielectric layer. The third and first electrodes are etched from a first metal layer. The fourth and second electrodes are etched from a second metal layer. The first and the fourth electrodes are connected by a connection through the dielectric layer to shield a mutual capacitance between the first and second capacitors.

  • Patent number: 7255573
    Abstract: Data signal interconnections are described that offer reduced cross talk particularly with high speed differential signaling. In one example, the invention includes a plurality of interconnects to carry data signals between a first component and a second component, the plurality of interconnects including a first set of interconnects oriented in a first direction and a second set of interconnects oriented in a second direction, different from the first direction.

  • Publication number: 20070146105
    Abstract: Complementary inductor structures. The inductor structure may include two or more sub-inductors that have positive coupling to provide a total inductance approximately equal to the sum of the inductance provided by the two or more sub-inductors. Radiation from the two or more sub-inductors may be in different phases to partially, or even totally, cancel and result in a reduced overall radiation, which may reduce electromagnetic interference and/or electromagnetic coupling.

  • Patent number: 7227247
    Abstract: In one embodiment, an integrated circuit package comprises a substrate including a first surface having a plurality of signal land pads and a second surface having a plurality of signal die pads; a plurality of signal connectors arranged to electrically couple the plurality of the signal land pads to the plurality of the signal die pads; and a ground plane, disposed in an adjacent, spaced-apart relationship to the plurality of signal land pads. The ground plane includes a plurality of holes with at least one of the holes having at least one of the signal connectors extending therethrough and being dimensioned and configured approximately to be as large or larger than at least one of the signal land pads disposed adjacent to the at least one hole.
