TSMC's Chief Financial Officer announced on a Monday investor call that the company is accelerating the construction of its $100 billion total investment wafer fab in Arizona, USA, to meet the surging market demand for artificial intelligence chips.



Taiwan Semiconductor Manufacturing's Arizona project represents the largest single foreign greenfield investment in U.S. history. Originally planned for construction in six phases, each with a capacity of approximately 50,000 wafers per month, the CFO revealed that Phase 1 achieved mass production in early 2025 and its current monthly capacity already exceeds 40,000 wafers, with a yield rate surpassing 95% of comparable facilities in Taiwan. Phase 2, initially scheduled for production by the end of 2027, has been brought forward to the first quarter of 2027. Phase 3 construction also commenced in May of this year, about four months ahead of the original schedule.



The impetus for this accelerated expansion comes directly from several major clients. Companies including Nvidia, AMD, Apple, and Qualcomm have all requested that TSMC increase its advanced process capacity on U.S. soil. With the explosive growth in AI training and inference demand, these companies' requirements for chips based on 3-nanometer and more advanced processes have far exceeded expectations.



TSMC's CFO stated that the Arizona fab's capacity is fully booked by major customers through 2028, indicating strong order visibility.



The U.S. government has expressed support for this development. A U.S. Department of Commerce official noted that TSMC's accelerated expansion aligns closely with the industrial objectives of the CHIPS and Science Act, aiding the long-term goal of boosting the U.S. share of global advanced chip manufacturing from less than 1% to over 20%. TSMC has already received approximately $11.6 billion in direct grants and loan support.



However, the accelerated expansion faces practical challenges. A notable shortage of local skilled technical personnel remains a prominent issue. TSMC has dispatched around 3,000 additional engineers and technicians from Taiwan to support the U.S. operations, which has sparked ongoing protests from local labor unions.



Water consumption is another contentious point. Located in an arid region, semiconductor manufacturing is water-intensive, and environmental groups have raised concerns about the fab's long-term water usage plans. TSMC has stated it has invested in building advanced wastewater recycling systems and is committed to achieving a plant-wide water recycling rate exceeding 80%.



TSMC estimates that upon completion of all six phases in Arizona, the complex could generate approximately $25 billion in annual output value, directly employ over 6,000 people, and create tens of thousands of additional jobs in the surrounding supply chain. The CFO emphasized that the company is advancing this investment at an unprecedented pace, with the goal of making the United States an indispensable part of the global AI chip supply chain.
