# IBM Unveils World's First Sub-1 Nanometer Chip, Packing 100 Billion Transistors on a Fingernail-Sized Die

> IBM announced the world's first sub-1 nanometer chip at 0.7 nm, packing 100 billion transistors with 50% more performance and 70% greater energy efficiency than its 2 nm predecessor.

IBM has debuted the world's first sub-1 nanometer chip technology, a 0.7 nm "Nanostack" design that crams nearly 100 billion transistors onto a piece of silicon no larger than a fingernail — roughly twice the density of IBM's own 2 nm chip from 2021. The breakthrough was announced on June 25, 2026, and relies on a three-dimensional architecture that stacks and staggers transistors vertically using complementary field-effect transistors (CFETs), building upward rather than shrinking laterally.

The new node delivers up to 50% more performance or up to 70% greater energy efficiency compared to the 2 nm generation, along with a 40% improvement in SRAM scaling. Industry analysts say the innovation could extend Moore's Law by another 10 to 15 years at a time when traditional lithographic scaling has nearly reached its physical limits. "This industry-first innovation continues IBM's legacy of leading in next-generation technologies and sets the foundation for the next era of computing," said Jay Gambella, Director of IBM Research.

Commercial chips based on the technology are still roughly five years from production, with IBM targeting deployment in data centres, GPUs, and CPUs within the decade. The announcement reinforces IBM's position as a semiconductor research leader alongside TSMC and Intel, which are pursuing their own advanced-node roadmaps for AI and high-performance computing workloads.
