[This Causes an Error]

Remember this is a chart of product yield, not defect density, and they are comparing yields of a 82mm^2 part on 14nm with a 130mm^2 22nm part; there's a lot more that can go wrong when you try to fabricate a 130mm^2 part than an 82mm^2 part, so the fact that the 130mm^2 part's yields are higher pretty loudly tells us something.

So yes, I completely agree that defect density on 14nm is substantially higher than at 22nm, which is why DCG is going to take it on the chip next year in terms of product costs as it transitions from 22nm parts to 14nm (very big dies).

And yes, the lack of an actual scale also serves to obscure things, too.
