IBM announced the world’s first sub-1 nanometer semiconductor technology at a 0.7nm node. This innovation utilizes a three-dimensional nanostack architecture to stack transistors vertically. The design departs from traditional two-dimensional chip layouts to maximize density.
The nanostack method fits nearly 100 billion transistors onto a fingernail-sized chip. This density doubles the capacity of IBM’s 2nm predecessor released in 2021.
The technology delivers up to 50% higher performance than 2nm chips. It also offers up to 70% greater energy efficiency. IBM expects this platform to sustain chip scaling for at least another decade.
The breakthrough addresses industry concerns regarding the physical limits of miniaturization. IBM anticipates moving the technology into production within approximately five years.
