  • Patent number: 8879266
    Abstract: Electronic devices having a multi-layer structure that provides enhanced conductivity (thermal and/or electrical conductivity) are disclosed. The multi-layer structure can have a plurality of adjacent layers. At least one layer can primarily provide structural rigidity, and at least another layer can primarily provide enhanced conductivity. The layer of high conductivity can serve to provide the electronic device with greater ability to disperse generated heat and/or to provide an accessible voltage potential (e.g., ground plane). Advantageously, the multi-layer structure can provide enhanced conductivity using an otherwise required structural component and without necessitating an increase in thickness.

  • Publication number: 20130250522
    Abstract: A heat sink employs a scalloped surface profile to facilitate interface to thermally conductive materials. The scalloped surface profile reduces the surface area initially as the thermally conductive material is compressed for assembly. The reduced surface area allows the required compression force to be decreased, which helps reduce the risk of damages to the heat generating devices due to excessive force. The scalloped surface profile increases the final surface area in contact with the thermally conductive material after assembly. The increased final surface area helps improve the transfer capacities of the heat sink.

    Abstract: Disclosed is a heat dissipation structure of an electronic device that has an IC chip that is a heat generating element mounted on a substrate and a heat dissipation sheet disposed between the IC chip and a cover member so as to dissipate heat. In such a heat dissipation structure, even if variation in a gap between the IC chip and the cover member is generated, the heat dissipation sheet can come in contact with the IC chip and with the cover member with appropriate pressure. This way, heat is sufficiently dissipated, and therefore, reliability of the electronic device can be improved. A heat dissipation sheet (1) has a double-layered structure in which a first heat dissipation sheet (11) and a second heat dissipation sheet (12) are laminated in a thickness direction.

  • Publication number: 20130003310
    Abstract: A chip package includes a processor, an interposer chip and a voltage regulator module (VRM). The interposer chip is electrically coupled to the processor by first electrical connectors proximate to a surface of the interposer chip. Moreover, the interposer chip includes second electrical connectors proximate to another surface of the interposer chip, which are electrically coupled to the first electrical connectors by through-substrate vias (TSVs) in the interposer chip. Note that the second electrical connectors can electrically couple the interposer chip to a circuit board. Furthermore, the VRM is electrically coupled to the processor by the interposer chip, and is proximate to the processor in the chip package, thereby reducing voltage droop. For example, the VRM may be electrically coupled to the surface of the interposer chip, and may be adjacent to the processor. Alternatively, the VRM may be electrically coupled to the other surface of the interposer chip.

  • Patent number: 8335083
    Abstract: An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.

  • Patent number: 8331092
    Abstract: A semiconductor element cooling apparatus includes: a first member whose first surface on which a semiconductor element is mounted, and whose second surface has fins that define coolant flow paths, and that extend in a first direction, and that stand from the second surface to a predetermined height, and that are spaced from each other by predetermined intervals; and a second member that defines the coolant flow paths that extend in the first direction. The fins have grooves which extend in a second direction that intersects the first direction, and which have a depth that extends from the distal end side of the fins toward the second surface. The depth of the grooves is smaller than the height of the fins. A protrusion-forming member is disposed in the grooves, and extends across adjacent fins, and forms protrusions in the coolant flow paths defined by the adjacent fins.
