Integrated circuit package including a heat pipe

A plastic-encapsulated integrated circuit comprising:

• a package formed of plastic,
• an integrated circuit embedded in the package, and
• heat-dissipating means for conducting heat from the integrated circuit, including:
• a hermetically sealed container formed of a heat conductive metal material bonded to the integrated circuit and extending therefrom to at least an outer surface of the package, and
• a volatile fluid disposed in the container for absorbing heat from the integrated circuit, without directly contacting the integrated circuit, while converting from a liquid state to a solid state, and
• evaporatively dissipating heat while converting from a vapor state to a liquid state, the container including first and second portions disposed adjacent the integrated circuit and the outer surface of the package, respectively, and an intermediate portion interconnecting the first and second portions, the intermediate portion being of smaller cross-section than the first and second portions.

A plastic-encapsulated integrated circuit comprising:

• a package formed of plastic;
• an integrated circuit embedded in the package, and
• heat-dissipating means for conducting heat from the integrated circuit, including:
• a hermetically sealed container formed of a heat conductive material embedded in the package and extending from the integrated circuit to at least an outer surface of the package with a lower end of the container being bonded to the integrated circuit by a heat-conductive adhesive;
• and
• a volatile fluid disposed in the container, for absorbing heat from the integrated circuit by converting the fluid from a liquid state to a vapor state without directly contacting the integrated circuit, and for evaporatively dissipating heat by converting the fluid from a vapor state to a liquid state.
