Abstract
Embodiments of the invention comprise a homogeneous heat spreading cap element in chip packages to facilitate better heat spreading and dissipation. The heat spreading cap comprises a single high-K graphite layer supported by a copper frame for increased stability and reduced thermal warpage during handling and operation while minimizing thermal penalty by reducing the amount of material having a relatively low heat conductivity that is needed in conventional heat spreading caps.
