Abstract

See full text

A computer module includes a substrate having redistribution layers comprising conductors and dielectrics formed on both sides of the substrate. Selected thin film conductors have a half pitch of 2 μm or less. Semiconductor components selected from bare die, chiplets, stacked devices, and low-profile packaged devices are flip chip mounted on the substrate. After grinding and polishing operations, a polished planar surface extends across each side of the substrate, coincident with the back side of the semiconductor components. Copper sheets are bonded to the polished planar surfaces using die attach films. A water-cooled server comprises multiple computer modules disposed in a tank with cooling water circulating around the modules. It dissipates 6.3 MW at a water flow rate of 339 gallons per minute and has a power density of 1 kW/in3.
