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.

Abstract:
An electronic package and method for spatially distributing a clock signal is presented. The electronic package includes a low-loss structure, a semiconductor die, clocking vias, and clock receivers on the die. The low-loss structure is constructed and arranged to be driven by a clock signal and to produce standing waves. The clocking vias are constructed and arranged to connect the low-loss structure to the die and to conduct the standing waves to the die. The clock receivers generate respective synchronous on-chip clock signals based at least in part on the conducted standing waves.
Abstract:
A method of fabricating a microelectronic package having a direct contact heat spreader, a package formed according to the method, a die-heat spreader combination formed according to the method, and a system incorporating the package. The method comprises metallizing a backside of a microelectronic die to form a heat spreader body directly contacting and fixed to the backside of the die thus yielding a die-heat spreader combination. The package includes the die-heat spreader combination and a substrate bonded to the die.
