On September 5, the U.S. government revoked the exemption that had allowed TSMC to ship crucial equipment to its major chip - manufacturing facility in mainland China. This action follows similar steps the U.S. previously took against South Korea's Samsung Electronics and SK Hynix.

Analysts in Taiwan point out that this decision is likely to hamper TSMC's chip - production capabilities in mainland China. In response, TSMC announced that it is currently evaluating the situation and implementing measures. These measures include engaging in communication with the U.S. government to safeguard the uninterrupted operation of its Nanjing plant.

The TSMC Nanjing plant mainly specializes in the production of mature - process chips, encompassing 16 - nanometer and 28 - nanometer technologies. These chips find extensive applications in automotive electronics, the Internet of Things, and various other sectors.
