CVD diamond film sink for high power MCMs

As electronic packages become more compact, run at faster speeds and dissipate more heat, package designers need more effective thermal management materials. CVD Diamond, because of its high thermal conductivity, low dielectric loss and its great mechanical strength, is an excellent material for three dimensional (3-D) multichip modules (MCMs) in the next generation compact, high speed computers and high power microwave components. In this paper, we have synthesized a large area free-standing diamond films and substrates, and polished diamond substrates, which make MCMs diamond film sink becomes a reality.
