IBM shares fell 1.86% to $258.07 after the company introduced the world’s first chip technology below one nanometer. The new 0.7-nanometer chip uses an advanced transistor structure and holds nearly 100 billion transistors. IBM expects the design to improve computing performance while reducing energy use across demanding workloads.

IBM Introduces New Nanostack Transistor Design
IBM developed a three-dimensional transistor architecture called nanostack to extend semiconductor scaling beyond existing nanosheet technology. The structure vertically stacks and staggers transistors, allowing designers to place more components within a smaller chip area. It also supports different materials across stacked layers, which improves control over power use and performance.
Researchers validated the design through thin dielectric bonding, dual-channel engineering, and working complementary metal-oxide semiconductor inverter tests. These experiments showed that the architecture can support physical production and perform the switching operations required for computing. IBM sees nanostack as a practical path toward chip development at the seven-angstrom technology node.
The company also demonstrated a 40% improvement in static random-access memory scaling during research presented at VLSI 2026. That advancement could give chip designers more memory capacity while preserving space for additional computing components. Denser memory could support the high-bandwidth data requirements of cloud platforms and large-scale machine learning systems.
Sub-1nm Chip Targets Higher Performance and Efficiency
IBM projects that the new technology could deliver 50% more performance than chips based on its two-nanometer technology. Manufacturers could achieve 70% greater energy efficiency while maintaining similar performance levels. These gains could support data centers, communication systems, transportation equipment, consumer devices, and other digital infrastructure.
The chip holds nearly twice the transistor density of IBM’s two-nanometer chip, which the company introduced during 2021. IBM achieved the increase through new materials, structural changes, and three-dimensional integration rather than traditional horizontal scaling. The company expects chip development to continue despite growing physical limits within conventional transistor designs.
Node names now describe manufacturing generations and no longer represent every physical feature within a semiconductor. However, IBM’s 0.7-nanometer demonstration shows that manufacturers can still increase density near atomic dimensions. The company’s semiconductor roadmap now outlines at least another decade of potential scaling through advanced architectures and materials.
IBM Targets Production Within Five Years
IBM conducts much of its semiconductor research at its Albany facility in New York alongside several industry partners. The facility will receive a High Numerical Aperture Extreme Ultraviolet lithography system developed by Dutch equipment maker ASML. This system prints smaller circuit patterns and supports future manufacturing processes for increasingly dense logic chips.
IBM also works with Lam Research, Tokyo Electron, and SCREEN Semiconductor Solutions on processes for High NA EUV production. The partners have already used related equipment and techniques to produce working semiconductor devices.IBM expects the research program to connect laboratory breakthroughs with future commercial manufacturing requirements.
The company expects manufacturers could adopt nanostack technology for production within the next five years. IBM continues developing silicon processors, artificial intelligence hardware, and quantum technologies alongside its traditional semiconductor research operations. IBM shares remained under pressure and stabilized near their intraday low following an earlier trading spike.
