Better Processors Through Carbon Dioxide
According to <a href="http://www.techreview.com/articles/upstream.asp" target="_blank">an article</a> in the Technology Review, researchers have discovered a way to use supercritical carbon dioxide to rinse processors and also to deposit 100nm copper wiring, both at extremely high degrees of accuracy and with no risk of damage to the chip.
As a bonus, the CO2 replaces ultrapure water and several nasty chemical solvents, reducing the environmental impact of chip manufacture.

The salient properties are that supercritical material has next to no viscosity and no surface tension. This means that it can get into extremely tight spots without gumming up, and that it doesn't exert pressure on the extremely small, delicate components it's cleaning - the surface tension of water is apparently strong enough to do just that.
Details are in the article.
har har har
Woops, I really should try harder, but i am just to lazy
Man Id love to see those some time.
