IBM just squeezed roughly 100 billion transistors onto a chip the size of a fingernail. That’s not a typo, and it’s not a theoretical exercise. On June 25, the company unveiled the world’s first 0.7-nanometer chip technology, crossing the sub-1nm threshold that many in the semiconductor world thought was still years away. To put the scale in perspective: a nanometer is one billionth of a meter. IBM’s new chip operates at 7 angstroms, which is 0.7nm. The technology uses what IBM calls a “nanostack” 3D transistor architecture, a design that stacks components vertically rather than just spreading them across a flat surface. IBM’s previous milestone was its 2nm chip technology, introduced back in 2021. The new 0.7nm design nearly doubles the transistor density of that already cutting-edge predecessor.
