You have to keep in mind that "nanotechnology" as a concept is not that useful in outlining applications and how they're engineered. You could equally well define refrigerators, wheels, motor vehicles and chairs as "macrotechnology," right? But that's not giving you any insight into the problems that are being solved.

There will be some areas of research where Intel's photolithography improvements are relevant and others where they're completely orthogonal, like repairing human tissue. That's just how these things go. :)
