A power outage at a TSMC supplier in Arizona caused a disruption at Fab 21, leading to the scrapping of some wafers in production. While the exact financial impact remains unclear, the outage affected the delivery of essential materials for operation. TSMC's reliance on outsourced functions in the U.S. leaves its facilities vulnerable to such interruptions, but understanding these weak points can help prevent future incidents. Operational disruptions are common in the semiconductor industry, and the financial implications of halting production at advanced fabs like Fab 21 can be significant.

US stops exports of tools to China’s number two chip maker — Hua Hong and Huali Microelectronics reportedly on the cusp of starting a 7-nm fab in Shanghai

The US Department of Commerce has instructed toolmakers to cease exports to Hua Hong, China's second-largest chipmaker, which is gearing up to establish a 7-nm production line in Shanghai. This move is part of the US strategy to impede China's semiconductor self-sufficiency efforts. Companies like TSMC and ASML have also faced restrictions in providing advanced services to Chinese tech firms. The ban on exports could strain US-China relations, impacting both Chinese companies' progress and potential losses for American toolmakers.
