Semiconductor Manufacturing International Corp has likely advanced its production technology by two generations, defying US sanctions intended to halt the rise of China’s largest chipmaker. From a report: The Shanghai-based manufacturer is shipping Bitcoin-mining semiconductors built using 7-nanometer technology, industry watcher TechInsights wrote in a blog post on Tuesday. That’s well ahead of SMIC’s established 14nm technology, a measure of fabrication complexity in which narrower transistor widths help produce faster and more efficient chips. Since late 2020, the US has barred the unlicensed sale to the Chinese firm of equipment that can be used to fabricate semiconductors of 10nm and beyond, infuriating Beijing.

A person familiar with the developments confirmed the report, asking not to be named as they were not authorized to discuss it publicly. SMIC’s surprising progress raises questions about how effective export controls have been and whether Washington can indeed thwart China’s ambition to foster a world-class chip industry at home and reduce reliance on foreign technologies. It also comes at a time American lawmakers have urged Washington to close loopholes in its Chinese-oriented curbs and ensure Beijing isn’t supplying crucial technology to Russia. The restrictions effectively derailed Huawei Technologies’s smartphone business by cutting it off from the tools to compete at the cutting edge — but that company is now quietly staffing up a renewed effort to develop its in-house chipmaking acumen.
