摘要: A compliant thermally conductive, preferably dielectric, compound that enhances the power dissipation capability of high-powered electrical components such as bipolar VLSI semiconductor chips. The compound has chemically stable thermal conduction and viscosity properties; is not subject to phase separation during use and may be applied in small gaps to maximize thermal conduction. The compound preferably comprises a liquid carrier having thermal filler particles dispersed therein and a coupling agent having a functionality which is reactive with the calcined surface of the thermal filler particles, and a functionality having preferential wetting of the thermal filler particles over self-condensation. Additional additives such as fumed silica and polyisobutylene enhance the phase stability and resistance to thermo-mechanical shear force degradation of the thermally conductive compound encountered during functional usage, e.g., fluctuating power cycles.

摘要: The cracking experienced during thermal cycling of metal:dielectric semiconductor packages results from a mismatch in thermal co-efficients of expansion. The non-hermeticity associated with such cracking can be addressed by backfilling the permeable cracks with a flexible material. Uniform gaps between the metal and dielectric materials can similarly be filled with flexible materials to provide stress relief, bulk compressibility and strength to the package. Furthermore, a permeable, skeletal dielectric can be fabricated as a fired, multilayer structure having sintered metallurgy and subsequently infused with a flexible, temperature-stable material to provide hermeticity and strength.
