IBM Introduces World's First Sub-1 Nanometer Chip Technology, Including Transistor Architecture At The 0.7 Nm Or 7 Angstrom Node

The achievement marks a landmark moment for an industry facing the physical limits of traditional chip scaling. Semiconductors play critical roles in everything from computing, to appliances, to communication devices, transportation systems, and critical infrastructure.

IBM Corp (IBM.US)'s new sub-1 nm chip packs nearly 100 billion transistors onto a chip the size of a fingernail, nearly twice the density of IBM's 2 nm chip, unveiled in 2021. Enabled by a series of structural and material innovations, including IBM's groundbreaking three-dimensional nanostack architecture, the technology demonstrates how continued gains in performance and efficiency remain possible even as chip features approach atomic dimensions.
