ABSTRACT:
A method and apparatus for dissipating heat from a semiconductor device. A heat sink embodying the method includes an exterior surface contoured to better facilitate heat dissipation and/or direct a flow of air or fluid over the heat sink. In one embodiment, the heat sink includes a heat sink layer formed from a powdered metal. In another embodiment, the heat sink layer is contoured with a selected combination of bumps, indentations and holes. In yet another embodiment, the heat sink includes a stack of such heat sink layers which are mechanically interfitted and thermally coupled.
