An integrated circuit heat dissipation system for reducing the number of junctions in packaged integrated circuits thereby decreasing thermal impedance and increasing thermal dissipation efficiency. The integrated circuit heat dissipation system includes a lid attached to a substrate, a cap attached about the lid creating a heat dissipation chamber, and a semiconductor chip attached to the lid by a thermally conductive adhesive. The lid may or may not form a cavity about the semiconductor chip depending upon the substrate utilized. The lid preferably includes a plurality of fins extending from thereof defining a plurality of channels or a plurality of grooves thereby increasing the heat flux of the lid.
