Much of the semiconductor industry has operated for decades via Moore’s Law, the foreshadowing that transistor counts effectively double about every two years. Yet, as engineers moved toward the atomic scale, skeptics anticipated an approaching wall. They argued that transistors could not shrink indefinitely, and would eventually be limited by quantum effects, heat, or simply the nature of materials.
IBM has unveiled the world’s first chip technology that scales below one nanometer, a feat once thought impossible, now realized at the 0.7 nm, or 7 angstrom node.
This fingernail-sized marvel contains nearly 100 billion transistors, each smaller than the width of a strand of DNA. It is not just another incremental advance in semiconductor scaling; it is a leap into the angstrom era, where dimensions brush against the size of individual atoms.
IBM’s new chip is a rebuttal to that fatalism. By introducing a radical transistor architecture called nanostack, IBM has shown that scaling can continue below the one-nanometer threshold. Nanostack is the industry’s first three-dimensional, nanosheet-based design.

Instead of laying transistors side by side, IBM stacks and staggers them vertically, using 3D sequential integration to pack more into the same footprint. Each layer can even employ different materials, tuned for performance or efficiency, like a skyscraper built from alternating steel and glass.
Compared to IBM’s 2 nm node chips, the new design promises up to 50 percent more performance or 70 percent greater energy efficiency. That means faster generative AI models, more efficient cloud infrastructure, and consumer devices that sip power rather than guzzle it.
IBM researchers experimentally validated ultra-thin dielectric bonding in CMOS integration, dual-channel engineering, and for CMOS inverter operation at the VLSI 2026 conference. Put simply, they…
