If I am not mistaken, a 14nm feature is about 20 or so Si atoms wide, so a 7nm feature would be about 10 or so Si atoms wide. If this is correct, clearly the next process node after 7nm (3.5nm, presuming halving each time) would be the last process node that allows an integer breadth (5 Si atoms). Beyond that you'd be down to non-integer feature breadths (or alternatively, non-integer average breadths with wide variances).
