Taiwan Semiconductor Manufacturing Company’s groundbreaking ceremony for its third fabrication facility in Arizona represents a monumental achievement in the company’s unprecedented $165 billion commitment to semiconductor manufacturing in the United States. The TSMC Arizona project officially commenced construction in late April 2025, marking a significant milestone that solidifies what stands as the largest foreign direct investment in American history.
Accelerated Project Timeline
In a notable development, TSMC Arizona has moved forward its construction schedule for the third fabrication facility. Initially planned for construction in 2026, the company accelerated the groundbreaking to 2025, demonstrating its commitment to expanding U.S. production capacity amid potentially growing demand for advanced semiconductors. This expedited timeline follows TSMC’s board meeting held on U.S. soil for the first time in the company’s 37-year history in February 2025, signaling the potentially increasing strategic importance of its American operations.
Leading-Edge Manufacturing Capabilities
The third facility will manufacture chips using 2-nanometer or more advanced process technology, with production potentially scheduled to begin by the end of this decade. This TSMC Arizona facility complements the first Arizona fab, which is expected to start volume production of 4-nanometer chips in late 2024, and a second fab currently under construction that will focus on advanced 2-nanometer technology with next-generation nanosheet transistors, targeted for production in 2028.
What distinguishes these facilities is their exceptional scale — each will feature cleanroom areas approximately double the size of a typical logic fab. This expanded capacity is designed to accommodate the extensive equipment required for leading-edge production, potentially positioning the complex at the forefront of semiconductor manufacturing technology in the United States.
Advanced Packaging Integration
Beyond chip fabrication, the company is enhancing its U.S. presence through advanced packaging capabilities. In October 2024, TSMC Arizona signed an agreement with Amkor Technology to collaborate on advanced packaging at Amkor’s planned $2 billion facility in Peoria, Arizona. The partnership focuses on TSMC’s Integrated Fan-Out (InFO) and Chip on Wafer on Substrate (CoWoS) packaging technologies, which are critical for smartphone applications and artificial intelligence GPUs.
The proximity of front-end fabs and Amkor’s back-end facility is designed to accelerate overall product cycle times, potentially creating a more integrated and efficient semiconductor manufacturing ecosystem. This collaboration addresses a crucial aspect of the semiconductor supply chain, which has been previously concentrated in Asia, allowing U.S. customers to have their chips both fabricated and packaged domestically.
Economic Transformation and Employment
The expanded operation represents a potentially transformative investment for the region’s economy. When fully operational, the three fabs are expected to create approximately 6,000 direct high-tech jobs. The construction phase alone may generate many direct construction jobs, with many additional indirect supplier and consumer jobs anticipated throughout this decade.
The company currently employs more than 3,000 people at its TSMC Arizona campus, which spans 1,100 acres. Beyond direct employment, the presence has catalyzed a broader semiconductor ecosystem in Arizona. The Greater Phoenix Economic Council reports that the region has attracted 39 semiconductor-related companies, resulting in the creation of more than 7,700 jobs and over $37 billion in capital investment. This clustering effect is transforming Phoenix into what some industry observers have dubbed the “Silicon Desert.”
Investment Growth and Government Support
The investment has undergone significant changes since its initial announcement. What began as a $12 billion commitment in 2020 expanded to $40 billion in 2022, then to $65 billion in 2024 with the addition of the third fab. In March 2025, an additional $100 billion investment brought the total to $165 billion.
Significant federal incentives under the CHIPS and Science Act have supported this expansion. In November 2024, the U.S. Department of Commerce finalized an award of up to $6.6 billion in direct funding for TSMC Arizona, along with up to $5 billion in loans. The company is also eligible for Investment Tax Credits of up to 25% on qualified capital expenditures.
Strategic Industry Partnerships
Major technology companies have expressed support for the project and its importance to their operations. NVIDIA’s Jensen Huang emphasized the importance of manufacturing AI infrastructure in America. AMD’s Lisa Su highlighted their relationship as one of the first and largest high-performance computing customers, stating they’re proud to begin production of their leadership 5th Gen AMD EPYC server processors later this year.
Apple has positioned itself as the largest customer at the TSMC Arizona facility, committing to sourcing chips as part of its broader $500 billion U.S. investment plan. The campus incorporates significant sustainability measures, including a target of 90% water recycling through an advanced Industrial Water Reclamation Plant designed to achieve “Near Zero Liquid Discharge.”
By the end of this decade, when all three Arizona fabs are operational, the facility will potentially establish a comprehensive semiconductor manufacturing ecosystem in the United States, thereby strengthening supply chain resilience for critical technologies and reducing dependency on offshore production.
