IBM Introduces the World’s First 2-nm Node Chip
Well if I were the referee I'd point out there's no scale bar on that. But this helps explain what we're looking at:
(from The Nanosheet Transistor Is the Next (and Maybe Last) Step in Moore’s Law)
I noted that the process uses silicon germanium, but only because there are chemicals which etch SiGe and not Si, so you can etch the SiGe layers away from between the Si to leave these free-standing Si ribbons.
