TSMC has started production of 4nm chips at a new plant in Arizona, which will cost more than the same chips from Taiwan

TSMC has officially started mass production of 4nm chips at its Fab 21 fab in Arizona, USA. This event was a major milestone for the US semiconductor industry.
Here's What We Know
TSMC CEO C.C. Wei confirmed that production began in the fourth quarter of 2024 using the N4P process, which offers yields comparable to operations in Taiwan. However, manufacturing in Arizona is more expensive due to higher amortisation costs, smaller scale of production, a weak local ecosystem and the additional cost of shipping chips back to Asia for packaging.
Despite this, customers appreciate the "geographic flexibility" of chips made in the US, even at higher prices. The Arizona plant, part of TSMC's $65 billion investment, is currently operating in Phase 1A with a production capacity of about 10,000 wafers per month. Among the fab's early customers are Apple, AMD and Nvidia, which are testing their chips produced at the facility.
TSMC plans to expand its presence in the US and introduce the 2nm process by 2028.
