IBM Claims First Sub-1 Nanometer Chip Technology

*IBM says its nanostack transistors mark the first chip process below one nanometer, with potential gains in performance or efficiency.*

IBM announced it has created what it calls the world’s first sub-1 nanometer chip technology. The company points to a new transistor design called nanostack as the basis for the claim.

The announcement appeared on IBM’s newsroom site and was covered by Ars Technica and Engadget. IBM states the transistors could raise either performance or energy efficiency, though it provided no further metrics or timelines in the initial release.

No independent verification or competing claims from other chip makers have surfaced yet.

Why it matters

Chip makers have spent decades shrinking transistors to pack more of them onto each die. IBM’s announcement extends that effort into territory below one nanometer, where conventional silicon scaling grows difficult. Whether the approach yields working products or remains a laboratory result will determine its effect on the broader industry.
