Tom's Hardware: U.S. Wants China's SMIC to Stop Making 14nm Chips. https://www.tomshardware.com/news/us-wants-china-smic-to-stop-making-14nm-chips
When the U.S. Department of Commerce (DOC) restricted access of China's largest contract chipmaker Semiconductor Manufacturing International Corp. (SMIC) to fab equipment used to make10nm-class chips, it was considered a tough but not too severe move. Now the U.S. government is mulling restricting China from producing logic chips using a 14nm-class fabrication process. The DOC is examining the possibility of prohibiting the exportation of chipmaking tools to companies in China that can make logic chips using 14nm-class manufacturing nodes and thinner, according to a Reuters report that cites five people familiar with the matter. The only company in China currently producing chips using its 14nm fabrication process is SMIC, which has been doing so since late 2019. What is not completely clear from the report is whether the DOC wants to ban SMIC from getting tools used to make semiconductors on its 14nm node and thinner, or if it wants to ban SMIC from getting any tools at all because it is capable of making chips using its 14nm technology.
