Cooling the next generation of chips
Subject: General Tech | June 5, 2008 - 08:59 AM | Jeremy Hellstrom
The research being done at IBM into cooling stacked or 3-D chips is focusing on water. They have managed to pipe water into cooling structures as thin as a human hair (50 microns) between the individual chip layers. They are getting some impressive results, which you can read about over at [H]ard|OCP.
"IBM Researchers, in collaboration with the Fraunhofer Institute in Berlin, demonstrated a prototype that integrates the cooling
system into the 3-D chips by piping water directly between each layer in the stack.
These so-called 3-D chip stacks – which take chips and memory devices that traditionally sit side-by-side on a silicon wafer
and stacks them together on top of one another -- presents one of the most promising approaches to enhancing chip performance
beyond its predicted limits."
