#276 Diamond can take the heat

While deliberating in the previous blog (#275) on the pivotal role carbon (in its various forms) is bound to play in future electronics, I should have made a stronger point regarding thermal properties of diamond. 


Well, even if it may be a well known fact, it is certainly not emphasaized enough: diamond is by far the best thermal conductor among all the solids. With its thermal conductivity in the range (depending on whether it is natural or synthetic)  of ~ 10-30 W/cmK, diamond is about six times better thermal conductor than copper. Considering challenges facing management  of heat generated by advanced logic ICs (and the need to dissipate it before the chip  will melt), it seems to be only a matter of time before synthetic diamond will become an integral part of all high-end IC packages.
