They went smaller than that if I recall.  They used a tunneling electron
microscope to actually build a transistor atom by atom.  Of course, that was
a tad labor intensive and not applicable to any known fab process.  :)  But
it did work although I don't remember how small the actual transistor actually
was.  But the number "A few atoms" comes to mind.  I'll try to find the
reference...

IE data-flow?  (Circa 1970 or so)??  :)
