  • Publication number: 20020051343
    Abstract: A heat dissipation system and method for extracting heat from an integrated circuit die includes attaching an integrated circuit die to a heat extraction substrate capable of extracting heat from the integrated circuit die. Further, a heat transport medium is attached to the heat extraction substrate, to transport the extracted heat from the heat extraction substrate to ambient. In some embodiments, the heat dissipation device can further include a heat sink, attached to the heat transport medium, to further facilitate the transporting of the heat from the heat transport medium to ambient.
