  • 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.
