ABSTRACT:
A diamond heat sink having a very high thermal property, to be used for radiation of semiconductor devices or compressors, includes a plate-shaped diamond substrate and fins for increasing the thermal property. The fins are combined with the substrate and are of a material having a heat conductivity of at least 1 (W/cm.multidot.K), for example, diamond. Such heat sink is produced by a simple process including arranging a base material and fins for growing diamond in such a manner that the surface of the base material and the upper ends of the fins are substantially the same height by the use of a suitable supporting member or by working the base material itself and growing diamond thereon by a gaseous phase synthesis method.
