Huawei Teardown Shows 5nm Chip Made in Taiwan, Not China (1)

Huawei Technologies Co.’s newest laptop runs on a chip made by Taiwan Semiconductor Manufacturing Co., a teardown of the device showed, quashing talk of another Chinese technological breakthrough.

The Qingyun L540 notebook contains a 5-nanometer chip made by the Taiwanese company in 2020, around the time US sanctions cut off Huawei’s access to the chipmaker, research firm TechInsights found after dismantling the device for Bloomberg News.
