Claim:
1. A method, comprising: supplying liquid coolant into a central inlet manifold formed through a central region of a chip stack, the chip stack comprising a plurality of conjoined chips disposed on a substrate; feeding liquid coolant from the central inlet manifold into flow channels that are formed between pairs of conjoined chips in the chip stack, wherein the liquid coolant is fed into the flow channels through inlet nozzles formed along a sidewall of the central inlet manifold of the chip stack, wherein the liquid coolant flows through the flow channels in a direction that is perpendicular to a flow of liquid coolant in the central inlet manifold; collecting heated liquid vapor that exits out from output ports of the flow channels around an outer periphery of the chip stack, wherein supplying liquid coolant into the central inlet manifold of the chip stack comprises: wherein collecting the heated liquid vapor comprises collecting the heated liquid vapor though a peripheral outlet of the package lid, wherein the peripheral outlet of the package lid is aligned to the peripheral output manifold region within the interior region of the package lid.
