Patent ID: 7656025

Claim:
A semiconductor package, comprising: a semiconductor chip having at least one heat-generating semiconductor device; and a volumetrically expandable chamber disposed to sealingly surround the semiconductor chip, the volumetrically expandable chamber entirely filled with a non-electrically conductive liquid in contact with the semiconductor device and circulated within the volumetrically expandable chamber at least in part by the generated heat of the at least one semiconductor device to cool the at least one semiconductor device; wherein the semiconductor chip is coupled to a substrate; and the volumetrically expandable chamber is formed by structures comprising a concave structure sealingly coupled directly to the substrate on a substrate surface facing the semiconductor chip; and a second semiconductor chip having at least one second heat-generating semiconductor, the second semiconductor chip coupled to a second substrate; wherein the structures further comprise a second concave structure sealingly coupled directly to the second substrate on a second substrate surface facing the second semiconductor chip; a community cover disposed on a side of the semiconductor chip and the second semiconductor chip, the integrated cover having passages permitting fluid communication between a first cavity formed by the concave structure, the substrate and the cover, a second cavity formed by the second concave structure, the second substrate and the cover; and a volumetrically expandable auxiliary chamber, coupled to the passages to permit the volumetric expansion of the non-electrically conductive liquid.
