TSMC says Japan plant survived 7.1 quake while Arizona fab begins AI GPU production
Taiwan Semiconductor Manufacturing Co. (TSMC) confirmed that its Japan Advanced Semiconductor Manufacturing (JASM) plant in Kumamoto was structurally intact after a magnitude‑7.1 earthquake on July 29. All employees were safely evacuated and accounted for, and the facility is being brought back online in phases. Inspections found no damage to the second‑phase construction, though some work remains paused pending aftershock risk.
In the United States, TSMC’s Fab 21 in Arizona successfully trial‑produced Nvidia’s GB300 AI GPUs using a 4‑nanometre process. The first chips have rolled off the line, but they must still be flown to Taiwan for advanced CoWoS packaging. TSMC plans a massive $2.65 trillion investment in the U.S., including two new advanced packaging plants in Arizona, to create a full‑scale domestic semiconductor supply chain. Foxconn has opened a GB300 server manufacturing base in Houston, Texas, and Wistron operates a server assembly line in Dallas, Texas, supporting downstream assembly.
Both developments reflect TSMC’s strategy to diversify its global manufacturing footprint, strengthen supply‑chain resilience, and reduce reliance on any single region.

Claims
What the coverage asserts, and how well corroborated each claim is across sources.
- [○ 1 SOURCE] TSMC plans to invest $2.65 trillion in the United States to build advanced packaging facilities. (TSMC outlined a $2,650 billion investment plan for U.S. fabs and packaging plants.)
- [● 3 SOURCES] Operations at the Japan plant are being restored gradually. (TSMC said production is being resumed in phases.)
- [● 3 SOURCES] TSMC's Arizona Fab 21 successfully trial‑produced Nvidia GB300 AI GPUs using a 4‑nanometre process. (TSMC announced the first GB300 chips rolled off the line.)
- [● 2 SOURCES] No damage was observed to the second‑phase construction of the Japan plant. (TSMC reported the second‑phase site was not affected.)
- [● 3 SOURCES] All employees at the Japan plant were safely evacuated and accounted for. (TSMC said all personnel were evacuated and accounted for.)
- [● 3 SOURCES] TSMC's Japan plant was structurally intact after the 7.1 magnitude earthquake. (TSMC confirmed the plant was unscathed.)
- [● 3 SOURCES] The GB300 chips produced in Arizona must be shipped to Taiwan for CoWoS packaging. (TSMC said the chips are air‑freighted to Taiwan for advanced packaging.)
