"Chiang said that the move to 20nm creates gate density and a chip performance to cost ratio that are superior to 22nm process technology"

why don't they skip to 1nm instead? it probably wont yield anyways but it sounds awesome!!! n_n

Hey TSMC, why not work out the problems with yields in 40nm before you go bragging about 20nm?

But, your ARM customers will be swept by Intel Atom.

in favour of 28nm (they probably couldn't solve the technical problems quick enough to make it worth while before 28nm became available) so 22 probably didn't look as attractive at that point.

Second half 2012.. that's simply great! 20nm! They had problems with 40nm... I'm worried that this is advertisement, not and announcement :(
