A Greener Chip Manufacturing Process

gardenermike writes "A new chip manufacturing process has been developed which uses UV light instead of high temperatures to prepare the silicon. This could lead to cheaper chips and greener factories if it pans out. Apparently the main problem is defects in the material, which are currently 'ironed out' as a side-effect of the extreme temperatures used."

Just in time to be obsolete

[erice]

Silicon dioxide is the all purpose dielectric in most current chips. It is slowly and painfully being replaced by "low K" materials between wires and "high K" materials under the gate electrodes. The transition to Low K/High K has been pushed out again and again but it is being used in some chips now. If the this new method of growing silicon dioxide is still in research, it seems doomed to reach production shortly after it is no longer needed.

Solar power applications?

Would this process also be useful for making silicon based solar cells? Or is it at a step of silicon processing that's too far towards chip specific manufacturing? If solar cells can be made more cheaply, I wonder what this could make the initial $/watt investment.
