Jun. 29, 2026 –
By Kang Da-eun, chosun.com
U.S. IT giant IBM has unveiled the world’s first semiconductor process technology below 1 nanometer (nm·one-billionth of a meter). If commercialized, the technology is expected to significantly reduce power consumption while dramatically boosting computing performance, serving as a technological breakthrough for AI data centers and next-generation high-performance semiconductors.
IBM announced on the 25th (local time) that it has developed a 0.7-nanometer (7 angstroms) process technology, the world’s first “sub-1nm” chip technology. While TSMC, Samsung Electronics, and Intel are competing to commercialize 2nm-class processes, IBM has presented a more advanced technology. In semiconductor processes, nanometers indicate fineness, with smaller numbers representing more sophisticated technology.
