Dec 20, 2011 at 21:52	comment	added	Polynomial		I'm aware of this, but transistors are highly complex in comparison with a mechanical device. In the case of producing very fine filters and sponge-like structures, 20nm is no big deal.

Dec 20, 2011 at 19:28	comment	added	Polynomial		Note that the above just refers to the overall transistor size. The internal layers and interconnects are often smaller than 1nm in at least one dimension. Clearly we already have the capability to produce simple parts at a much smaller scale than 100nm.
Dec 20, 2011 at 19:19	comment	added	Polynomial		I question your "100nm scale microprocessors" remark. We can manufacture microprocessors down to at least 30nm, if not lower. I think the current minimum transistor size is 14nm. Update: Intel and IBM are using 14nm in next-gen fabrication, several other companies are using 15nm. Intel have also been experimenting with 12nm and 11nm units.
