Abstract

Removal of heat from modules containing high power semiconductor chips can be accomplished in a variety of ways. One technique, shown in Fig 1A, uses conduction through a solid body 10, such as a metal piston, to provide a low resistance path between an IC chip 12 and the package containing them. A spring-loading mechanism 14 insures close contact between the piston and the chip, thereby minimizing interface resistance.
