Abstract
A package for an integrated circuit that is attached to a rigid substrate by the flip-chip method has a heat spreader that is attached to the IC by a thermally conductive, compliant adhesive and that is attached to the package substrate by a set of rigid posts of adhesive, the result of which is that the heat spreader is more closely parallel to the substrate than was the case for a stiffener bonded to the substrate by a thin film extending over a large area.
