Abstract:
Integrated circuit (IC) packages employing two-phase microchannel heat exchangers for cooling the packages' IC dies and cooling systems employing the same are disclosed. The heat exchangers include thermal masses having a plurality of microchannels formed therein. In one set of configurations, the IC die is thermally coupled to a pair of microchannel heat exchangers disposed on opposite sides of the die. Top-side microchannel heat exchangers include a thermal mass having a plurality of open microchannels having wall bases that are hermetically sealed with the top surface of the die, thus forming a plurality of closed microchannels. Alternatively, a separate microchannel heat exchanger is thermally coupled to an IC die and operatively coupled to the IC die via coupling to a substrate on which the IC die is mounted. Bottom-side heat exchangers include substrates and chip carriers having microchannels formed therethrough that are thermally coupled to the IC die. The cooling systems employ a plurality of microchannel heat exchangers to cool selected electronic components.
Abstract:
The present invention discloses a method of confining a liquid metal alloy within a closed-loop system; distributing a first portion of the liquid metal alloy in a cavity within the closed-loop system; turning on an electromagnet to generate a magnetic field to permeate flexible sidewalls of the cavity; attracting the liquid metal alloy in the cavity towards the electromagnet to expand the flexible sidewalls; inducing a second portion of the liquid metal alloy to enter the cavity from an inlet end of a heat pipe within the closed-loop system; turning off the electromagnet; repelling the liquid metal alloy in the cavity away from the electromagnet to contract the flexible sidewalls; and inducing a third portion of the liquid metal alloy to exit the cavity to an outlet end of the heat pipe.
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:
A microelectronic die is provided having an integrated thermoelectric module. The microelectronic die has a die substrate, a microelectronic circuit formed on a front side of the die substrate, and the thermoelectric module on a backside of the die substrate. Vias in the substrate interconnect the thermoelectric module with power and ground planes on the front side of the die substrate.
Abstract:
An integrated circuit package that contains an underfill material between an integrated circuit and a substrate. The integrated circuit may be mounted to the substrate with solder bumps in a C4 process. The underfill material may extend from an edge of the integrated circuit a length that is no less than approximately 25% of the length between the integrated circuit edge and the integrated circuit center. It has been discovered that a length greater than approximately 25% does not provide a significant reduction in the strain of the solder bumps.
Abstract:
A flip chip integrated circuit package which provides stress relief for the solder bumps of the package. The package includes an integrated circuit that is mounted to a substrate. The integrated circuit is attached to a plurality of bond pads of the substrate by a number of corresponding solder bumps. The substrate has a first layer that is attached to a second layer. An area that is located between the layers and adjacent to the bond pads is left unattached so that a portion of the first layer can move independent of the remaining portion of the substrate. The unattached area allows the integrated circuit to “float” and expand at a different rate than the substrate when the package is thermally cycled.
