Abstract

A plastic-encapsulated integrated circuit includes a package formed of plastic, an integrated circuit embedded in the package, and heat-dissipating means for conducting heat from the integrated circuit, which means include 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, and a volatile fluid disposed in the container. In operation, the volatile fluid absorbs heat from the integrated circuit when it changes from the liquid state to the vapor state, and dissipates heat when it changes from the vapor state to the liquid state.
