摘要： A multi-chip module and heat-sink cap assembly and method of fabrication, which provides sufficient cooling for higher power density chips. The heat-sink cap has heat-sink columns disposed over each chip on a substrate. The heat-sink columns are interconnected by flexible members to provide a unitary cover. Thin film metallization of at least a portion of the mating surfaces of the substrate, chips and heat-sink column permits soldering of the cap to the chips and substrate to form the package which is a mechanically stable structure with no degradation of interconnection fatigue life due to thermal cycling of the assembly when in use.

摘要： A ternary-alloy/glass composite suitable for use in vias in glass-ceramic electronic structures includes gold, palladium, and either platinum or silver in the alloy where the gold is less than 50% by weight of the alloy. The alloy is combined with glass frit where the glass is present as 5-50% by volume in the composition. The ternary-alloy glass composite is sintered in the glass-ceramic structure and provides a hermetic seal. Chips and pins can be bonded directly to the ternary-alloy/glass composite using a eutectic braze without causing cracks in the glass-ceramic. The ternary-alloy/glass composite has good adhesion with glass-ceramics and is useful in vias in electronic structures.

摘要： Solder compositions are introduced to interface between an IC chip and its associated heat exchanger cover. The solder compositions have a solidus-liquidus temperature range that encompasses the IC chip operational temperature range. The solder composition has the desired property of absorbing and rejecting heat energy by changing state or phase with each temperature rise and decline that result from temperature fluctuations associated with the thermal cycles of the integrated circuit chips. A path for high thermal conduction (low thermal resistance) from the IC chip to the heat exchanger to the ambient air is provided by an electronic module cover, configured as a cap with a heat exchanger formed or attached as a single construction, and made of the same material as the substrate, or made with materials of compatible thermal coefficients of expansion to mitigate the effects of vertical displacement during thermal cycling. The cap-heat exchanger cover is constructed to be compliant, and to contact both the IC chip and substrate.
