  • Patent number: 8648478
    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.

  • Patent number: 8250750
    Abstract: A method for manufacturing a tape wiring board in accordance with the present invention may employ an imprinting process in forming a wiring pattern, thereby reducing the number of processes for manufacturing a tape wiring board and allowing the manufacturing process to proceed in a single production line. Therefore, the manufacturing time and cost may be reduced. A profile of the wiring pattern may be determined by the shape of an impression pattern of a mold. This may establish the top width of inner and outer leads and incorporate tine pad pitch. Although ILB and OLB process may use an NCP, connection reliability may be established due to the soft and elastic wiring pattern.
