TSMC, Intel, and Samsung have all been pushing to produce low‑single‑nanometer chips in the next two years, while planning to produce sub nanometer chips sometime by decade's end. That race may be over, however, even before it began. IBM unveiled what it says is the world's first sub 1 nanometer chip technology based on a new 3D NanoStack transistor architecture at the 0.7 nm — or 7 angstrom — node. The research device, introduced ahead of VLSI 2026
