But when it comes to cost, evidently replacing many passes and other complicated processes with DUV machines with fewer EUV passes is a net win. And the energy required to create these chips must be a small fraction of the energy they will use in their lifetimes, so improved efficiency of the smaller nodes enabled by EUV would surely be a win, all else being equal.
