ABSTRACT:
The capability of the microbellows cooling technique to remove heat from multi-chip modules is enhanced with a highly conductive, rigid, heat spreader. The heat spreader has a planar surface urged against a planar surface of the chip by the flexible microbellows. The surface area of the heat spreader is greater than the mating surface area of the chip. The heat spreader is attached to the bottom surface of the microbellows. The surface area of the heat spreader which mates with the surface of the chip is highly polished and coated with a highly conductive soft metal. A jet of coolant is forced into the inner surface of the microbellows.
