We are coming to the end of Moors Law. It will be larger than the 5 atoms listed in the Article.
Experiments from the mid 1990's on showed what the limits of miniaturization really are. For a transistor, it is 7 atoms. For a capacitor, it's around 100 times that. For a wire, metal wires have to be at least 60 atoms wide to reliably carry current. The proposals to use Nano tubes are about that size. So, the limit on lithography will be established with the minimum size that can connect trace wires that are 60 Atoms wide, or around 5 to 10 nanometers. That's about eight times denser than anything we can achieve today.
We have already reached one limit on Moors Law. The increases in clock speed that were expected and commonplace 20 years ago are no longer happening. the reason is that the heat dissipated in the circuit is a function of the frequency. by 2002, the fastest chips were literally melting the microprocessor. That's the whole reason for water based cooling, and other attempts to increase cooling.
To be able to increase the clock speeds again, we will need to replace silicone with carbon. That lets us raise the temperature of the chips by over an order of magnitude.
Moors law will not stop, it will instead just slow down.
For example, between 1980 and 1990, microprocessor speed went from 3 MHZ on the original PC, to 100 MHZ on the Pentium. From 1990 to 2000, microprocessor speed went from 100 MHZ to 400 MHZ. From 2000 to 2010, microprocessor speed went from 400 MHZ to around 2 to 3 GHZ. There it stalled since around 2004. Intel doesn't even advertize it's products any more based on processor speed. There have been increases in processor speed, but, they are not dramatic any more.
