Abstract: A system is disclosed. The system includes an external waveguide and an IC coupled to the external waveguide. The IC includes at least two lenses and a second waveguide. The lenses couple radiant energy from the external waveguide to the second waveguide.

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: Embodiments of the invention provide one or more valves in which an electroactive material acts to open or close the valves to increase efficiency of a pump, which may be a pump that uses an electroactive diaphragm to pump fluid. The valves and pump may pump fluid to cool a device in a system.

Abstract: An IC package is assembled from a bumpless die, a die carrier having a plurality of solder bumps thereon, and a heat spreader lid. The bumpless die is bonded to the heat spreader lid to form a module and then the module is bonded to the bumped die carrier.

Abstract: A die package and a method and apparatus for integrating an electro-osmotic pump and a microchannel cooling assembly into a die package.

Abstract: A low cost technique for packaging microelectronic circuit chips fixes a die within an opening in a package core. At least one metallic build up layer is then formed on the die/core assembly and a grid array interposer unit is laminated to the build up layer. The grid array interposer unit can then be mounted within an external circuit using any of a plurality of mounting technologies (e.g., ball grid array (BGA), land grid array (LGA), pin grid array (PGA), surface mount technology (SMT), and/or others). In one embodiment, a single build up layer is formed on the die/core assembly before lamination of the interposer.

Abstract: A system may include a plurality of pliant conductive elements, a first end of one of the plurality of pliant conductive elements to be electrically coupled to a first electrical contact of an integrated circuit substrate and a second end of the one of the plurality of pliant conductive elements to be electrically coupled to a second electrical contact of an integrated circuit die.

Abstract: Optical devices and methods for constructing the same are disclosed. An example optical device includes an optical transmitter, a photodetector and a waveguide optically coupling the optical transmitter and the photodetector. It also includes a substrate having a first cavity to receive the optical transmitter and a second cavity to receive the second transmitter. The first and second cavities are located and dimensioned to passively align the optical transmitter, the waveguide and the photodetector when the transmitter is inserted into the first cavity and the photodetector is inserted into the second cavity.

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.
