IBM Unveils Breakthrough Sub-1 Nanometre Chip Technology

On June 25, 2026, IBM announced a groundbreaking leap in semiconductor engineering with the creation of the world’s first sub-1 nanometer, or 0.7 nm, chip technology.

As traditional horizontal scaling reaches its physical limits, IBM has introduced a new paradigm called 'nanostack' architecture.

Instead of simply shrinking components, this method utilizes 3D sequential integration to stack transistors vertically.

This innovative design allows for incredible density, fitting nearly 100 billion transistors onto a chip the size of a fingernail—double the capacity of previous 2 nm chips.

Beyond mere size, the performance benefits are staggering.

This new technology promises up to 50% higher performance or 70% greater energy efficiency, the latter being a crucial development for the power-hungry AI industry.

IBM anticipates this technology will reach the manufacturing stage within the next five years, ensuring that progress in computing power continues well into the next decade.
