It was nice when we had round numbers to work with. It was pretty simple to move from 180nm to 120nm and then to 90nm. Then the half nodes started—45/40, 32/28 and 22/20nm.
After 14nm we are poised dangerously over the single-digit process nodes. Intel is working on 10nm, to be followed by 7nm or 5nm. Other companies are looking at 11nm, to be followed by 8nm, 6nm or something even further...
