摘要：Heat spreaders can help promote heat distribution at the surface of a heat sink. However, overly isotropic or anisotropic heat conduction through heat spreaders can limit their effectiveness. Heat spreaders providing for lateral distribution of heat can include a tapered structure containing a metal-diamond composite. The metal-diamond composite includes a continuous metallic phase and a plurality of micron-scale diamond particles located in spaced apart regions of the continuous metallic phase. An interlayer containing the continuous metallic phase but lacking micron-scale diamond particles is disposed between each of the spaced apart regions, and the metal-diamond composite increases in lateral size in a direction of increased tapering. Heat spreaders can be formed by disposing a first mixture containing micron-scale diamond particles and metal nanoparticles in first regions that are vertically spaced apart from each other, and at least partially fusing the metal nanoparticles to form a tapered structure.
