  • Patent number: 10276475
    Abstract: A thermal conductive stress relaxation structure is interposed between a high-temperature substance and a low-temperature substance to conduct heat in a heat-transfer direction from the high-temperature substance to the low-temperature substance. The structure includes an assembly configured such that a thermal conductive material gathers in a non-bonded state having stress relaxation effect. Such an assembly is a rolled-up body configured such that a carbon-based sheet material and a metal-based sheet material are alternately rolled up, for example. This structure has one or more interfaces at which adjacent parts can slide, thereby dividing a deformable region to relax the thermal stress. It has a low rigidity and can thus deform to release the thermal stress. The structure can suppress the thermal stresses and the shape changes that would be generated in the high-temperature substance and the low-temperature substance, and each physical body located there between.

  • Patent number: 7683479
    Abstract: A semiconductor chip 36 is mounted on a package substrate 30 with its circuit side facing to a board 38. Heat is dissipated from an upper side of the semiconductor chip 36 opposite to the circuit side. A sealing resin 32 seals around the periphery of the semiconductor chip 36 so that the upper side of the semiconductor chip 36 is exposed to atmosphere. A fixing member 34 is buried in the sealing resin 32 so that a hook 40 formed on the tip of the fixing member 34 extends above the upper side of the semiconductor chip 36. A spreader 10 dissipates heat emitted from the semiconductor chip 36. A guiding slot 12 is formed on the side facing to the package substrate 30 of the spreader 10. The hooks 40 of the fixing members 34 are inserted into the guiding slots 12 respectively, and then the spreader 10 is rotated by predetermined angle against the package substrate 30. Then, the hooks 40 travel along the slots 12.

  • Patent number: 7638814
    Abstract: Standard solderless connectors extend from a molded package body supporting at least one high power LED. The package includes a relatively large metal slug extending completely through the package. The LED is mounted over the top surface of the metal slug with an electrically insulating ceramic submount in-between the LED and metal slug. Electrodes on the submount are connected to the package connectors. Solderless clamping means, such as screw openings, are provided on the package for firmly clamping the package on a thermally conductive mounting board. The slug in the package thermally contacts the board to sink heat away from the LED. Fiducial structures (e,g., holes) in the package precisely position the package on corresponding fiducial structures on the board. Other packages are described that do not use a molded body.

  • Patent number: 7427809
    Abstract: A tightly packed three-dimensional electronic system or subsystem comprising multiple stacks of semiconductor elements is described. The system is repairable because the elements connect together using re-workable flip chip connectors; each flip chip connector comprises a conductive spring element on one side and a corresponding well filled with solder on the other side. The spring elements relieve stresses at the interfaces and allow the component stacks to remain flat; they also provide vertical compliance for easing assembly of elements that have been imperfectly thinned or planarized. Semiconductor integration platforms may be used to integrate active and passive devices, multi-layer interconnections, through wafer connections, I/O plugs, and terminals for attachment of other semiconductor elements or cables.
