-Huawei Technologies’ new MateBook Fold laptop is powered by an older-generation chip made by SMIC, highlighting how U.S. export curbs are hindering China’s top foundry from advancing to next-generation semiconductor manufacturing.The laptops are the first to be sold with Huawei’s Harmony operating system. It has not officially disclosed the processor used, though past models have used Intel chips.The U.S. curbs limited SMIC’s access to advanced chipmaking tools, including extreme ultraviolet lithography. China-based foundries have to now rely on less efficient multi-patterning techniques that reduce yield. Will US criple China semi-conductor supply chain completely ?
