IBM unveils tech for chip smaller than 1 nanometer in AI computing push

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% in premarket trading, ‌though later pared ⁠gains ⁠to about 1.9%. They have fallen about 11% 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.
