  • Patent number: 8184439
    Abstract: A semiconductor module includes a semiconductor package generating thermal energy, a heat collecting member transferring thermal energy from the semiconductor package to a heat collection area in the heat collecting member, a heat radiating member transferring thermal energy received from the heat collecting member and package to the outside, and a thermoelectric device transferring thermal energy through the heat collection area to the heat radiating member via the thermoelectric effect. The heat collecting member and heat radiating member may be otherwise insulated so thermal energy is transferred and controlled by the thermoelectric device. The package may be a dynamic random access memory (DRAM), microprocessor, central processing unit (CPU), graphic processing unit (GPU), or flash memory. The heat radiating member may be an external case of a solid state disk (SSD), and the thermoelectric device may be a Peltier cooler controlled through a power line.

  • Publication number: 20120119351
    Abstract: A system for clamping a heat sink that prevents excessive clamping force is provided. The system may include a heat sink, a semiconductor device, a printed circuit board, and a cover. The semiconductor device may be mounted onto the circuit board and attached to the cover. The heat sink may be designed to interface with the semiconductor device to transfer heat away from the semiconductor device and dissipate the heat into the environment. Accordingly, the heat sink may be clamped into a tight mechanical connection with the semiconductor device to minimize thermal resistance between the semiconductor device and the heat sink. To prevent excessive clamping force from damaging the semiconductor device, loading columns may extend between the cover and the heat sink.

  • Patent number: 8174112
    Abstract: An integrated circuit device includes an integrated circuit formed in a semiconductor die and an integrated circuit package containing the semiconductor die. The integrated circuit package includes a thermal interface material substantially between the semiconductor die and a heat spreader of the integrated circuit device for conducting heat from the semiconductor die to the heat spreader. The thermal interface material includes diamond particles and has a thickness selected to reduce capacitance between the semiconductor die and the heat spreader over that of a conventional integrated circuit device without reducing the rate of thermal conduction from the semiconductor die to the heat spreader. As a result, the integrated circuit device has improved electrostatic discharge immunity.

  • Patent number: 8134835
    Abstract: The present invention relates to a clamping device for compression clamping of one or more semiconductor devices and associated semiconductor components with a desired compression force equally distributed across the opposing surfaces of the devices and associated components. The semiconductor devices and components are located between opposing jaws that are joined together by at least two tie rods, which compressively load the opposing jaws to apply the desired compression force to the semiconductor devices and components. The desired compression force is first achieved in even distribution between independent clamp pressure set point assemblies and the first jaw, where each of the independent clamp pressure set point assemblies is associated with one of the tie rods.

  • Patent number: 8120171
    Abstract: A power drive unit is configured to comprise a heat sink, a power module pressed by a press member to the heat sink to be fastened thereto and a spring member that has a substantially circular shape and is installed between the power module and the press member. With this, the power module can be fastened to the heat sink without incurring layout limitation, degradation of heat release performance and the like. Also, since the power drive unit further includes a projection that protrudes from the press member to be engaged with an engagement hole bored at the center of the spring member, engagement of the projection of the press member with the engagement hole of the spring member functions to prevent displacement of the press member relative to the spring member, thereby making loads acting on the power modules uniform.

  • Patent number: 8115301
    Abstract: Methods for fabricating flip-chips are disclosed. In an exemplary method, a flip-chip is mounted, active-surface downward, onto a substrate such that a back-side of the flip-chip is facing upward and electrical connections are made between the chip and an upward-facing surface of the substrate. An adhesive is applied to selected regions not occupied by the flip-chip. A heat-spreader is applied to contact the applied adhesive without contacting the back-side of the flip-chip, leaving a gap between the heat-spreader and the back-side of the flip-chip. The heat-spreader defines at least one through-hole that, when the heat-spreader is placed, is within a perimeter of the flip-chip. The adhesive is cured, and a thermal-insulating material (TIM) is applied through the at least one through-hole so as to fill the gap with the TIM. The methods substantially reduce the probability of die damage that otherwise occurs during attachment of heat-spreaders.

    Abstract: A heat sink includes a first adhesive layer, and a heat dissipation layer disposed on the first adhesive layer, and has ventilation ports that extend therethrough including through the first adhesive layer and the heat dissipation layer. The heat sink forms an outermost part of a semiconductor package. Thus, when the heat sink is bonded via its adhesive layer to underlying structure during a manufacturing process, the ventilation ports allow air to pass therethrough. As a result, air is not trapped in the form of bubbles between the heat sink and the underlying structure.
