New York, 25 June 2026 – IBM has unveiled what it describes as the world’s first chip technology capable of producing semiconductors smaller than one nanometre, marking a major step in the race to build more powerful and energy-efficient processors for artificial intelligence workloads.
The technology features a 0.7 nanometre, or 7 angstrom, transistor architecture known as nanostack. IBM said the breakthrough could allow nearly 100 billion transistors to fit onto a chip the size of a fingernail, almost twice the density of the 2 nanometre chip it introduced in 2021.
