First Claim
Patent Images
1. A packaged integrated circuit comprising:
- a stack including an integrated circuit chip to be cooled and a cooling integrated circuit chip formed of a semiconductor substrate, said cooling integrated circuit chip including microchannels formed in said substrate for the circulation of a cooling fluid through said cooling integrated circuit chip;
an integrated circuit package receiving said stack, said substrate having formed therein an inlet fluid reservoir and an outlet fluid reservoir to communicate with said microchannels; and
an external heat exchanger mounted on said package by a pair of cooling fluid circulating tubes.

Abstract
An integrated circuit to be cooled may be abutted in face-to-face abutment with a cooling integrated circuit. The cooling integrated circuit may include electroosmotic pumps to pump cooling fluid through the cooling integrated circuits via microchannels to thereby cool the heat generating integrated circuit. The electroosmotic pumps may be fluidically coupled to external radiators which extend upwardly away from a package including the integrated circuits. In particular, the external radiators may be mounted on tubes which extend the radiators away from the package.
