June 25 : IBM on Thursday unveiled what it said was the world’s first technology capable of producing chips smaller than one nanometer, as tech companies race to build semiconductors that can handle increasingly demanding AI workloads.
Shares of the Armonk, New York-based company rose over 6 per cent in premarket trading. They have fallen about 11 per cent so far this year.
The announcement comes at a time when chipmakers are searching for ways to maintain the decades-long trend of cramming more computing power into smaller spaces, a phenomenon known as Moore’s Law.
The new chip technology, which bolsters IBM’s position to compete with contract chipmakers TSMC and Intel, has a transistor architecture of 0.7 nanometers, or 7 angstroms.

Last week, Intel said the new generation of its 18A manufacturing process, which makes 1.8 nanometer chips, moved into risk production, the testing phase before commercial manufacturing.
IBM said the 0.7-nanometer chip packs nearly 100 billion transistors onto a fingernail-sized surface, about twice the density of its 2-nanometer chip unveiled in 2021, delivering up to 50 per cent higher performance or 70 per cent greater energy efficiency.
To get there, IBM developed a new transistor design called “nanostack”. Instead of laying transistors flat, the design stacks them on top of each other in three dimensions, fitting more into the same volume of space.
“With our new nanostack architecture, we’re not just making smaller transistors, we’re reinventing how chips are built to deliver dramatically more power and energy efficiency,” director of IBM Research Jay Gambetta said.
IBM says production could begin within five years. The company has previously licensed chip technologies to Samsung and Japan’s Rapidus. It has not announced a manufacturing partner for this technology.
