The operation of highly integrated semiconductor devices generates a significant amount of heat which must be dissipated. This heat is conventionally dissipated by either backbonding the device to a suitable substrate and making some suitable cooling provision for the substrate, or, in the instance of flip-chip bonded devices, removing heat from the backside of the device with cooling pistons or other means that serve as a heat conduction bridge to fins or a cooling sink. A structure that can be used for cooling a device 10, solder bonded to substrate 12, is a layer of thermal grease 14 located between device 10 and finned cap 16.
