Huawei’s New Laptop Adds to Evidence of Stalled Chip Advance

Huawei Technologies Co.’s latest computer product is powered by a chip manufactured using years-old technology, suggesting US sanctions are still preventing China from developing cutting-edge semiconductor technologies.

The processor in the MateBook Fold is built with domestic partner Semiconductor Manufacturing International Corp.’s 7-nanometer technology, according to Canada-based consultancy TechInsights, employing the same process technology adopted in the Mate 60 Pro that stunned US officials two years ago. Industry leader Taiwan Semiconductor Manufacturing Co. is expected to start mass producing 2nm chips, which is three generations ahead of 7nm, later this year.
