(Bloomberg) — Semiconductor Manufacturing International Corp. has likely advanced its production technology by two generations, defying U.S. sanctions intended to halt the rise of China’s largest chipmaker.

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 U.S. has barred the unlicensed sale to the Chinese firm of equipment that can be used to fabricate semiconductors of 10nm and beyond, infuriating Beijing.
