How scaling is done from 90 to 45nm then to 22nm directly?

How scaling is done from 90 to 45nm then to 22nm directly??

will designers check from 90, 89, 87...50,49..45 likewise??

or will designers predict an optimistic length(nm) at the very early stage and start analysing??


plzz explain briefly how its happening.

nm Technology

it is purely based on invention of new methods for mask formation.... by increasing the precision with which the mask can be made the technology is scaled....
