TSMC: Challenges building a Greenfield Project in Arizona

/ editor

Building the Taiwan Semiconductor Manufacturing Company (TSMC) factory in Arizona has been a complex undertaking marked by both significant successes and notable failures and challenges. The project, which started with a $12 billion investment and has since expanded to a monumental $165 billion, represents the largest foreign direct investment in a greenfield project in U.S. history.

Successes

The project has achieved several key milestones and successes, most recently turning a profit and demonstrating strong operational performance.

  • Financial Performance: The Arizona facility achieved profitability in the first half of 2025, a significant turnaround from previous losses. This was attributed to high factory utilization and strong market demand, particularly for chips used in AI applications. The facility is a major contributor to TSMC’s overall earnings, demonstrating that the U.S. manufacturing site is a viable part of the company’s global strategy.
  • High Yield Rates: The TSMC Arizona factory has achieved a remarkable milestone by surpassing the yield rates of its counterpart facilities in Taiwan. Yield rates, which measure the percentage of functional chips produced per wafer, are critical for efficiency and profitability in the semiconductor industry. This success proves that TSMC has successfully adapted its advanced manufacturing techniques to a U.S. environment.
  • Economic Impact and Job Creation: The project has had a transformative effect on the Phoenix area and the broader U.S. economy. It has led to the creation of over 40,000 construction jobs and thousands of high-paying, high-tech jobs. The investment has also spurred growth in supporting industries like real estate, healthcare, and retail, and is contributing to the development of a new high-tech workforce in Arizona.

Failures and Challenges

Despite its successes, the project has been plagued by delays, logistical hurdles, and cultural clashes.

  • Construction Delays and Cost Overruns: The initial production timeline for the first fab was pushed from late 2024 to 2025. Similarly, the second fab’s timeline was delayed from 2026 to at least 2027 or 2028. These delays have been attributed to several factors, including a shortage of skilled labor, unexpected costs, and supply chain issues. TSMC’s founder, Morris Chang, has warned that production costs in Arizona could be significantly higher than in Taiwan.
  • Labor Disputes and Shortages: A major challenge has been the shortage of skilled workers in the U.S. with the specialized expertise required for advanced semiconductor manufacturing. This has led TSMC to seek visas for hundreds of Taiwanese technicians, which sparked controversy and criticism from local labor unions. While an agreement was eventually reached, the issue highlighted a key challenge in “reshoring” advanced manufacturing to the U.S.
  • Cultural and Logistical Hurdles: Reports from both sides indicate significant cultural differences in work practices. American engineers have complained about rigid hierarchies, while some Taiwanese veterans have expressed concerns about what they perceive as a lack of dedication from their American counterparts. Logistical issues, such as constantly changing blueprints and project plans, have also contributed to delays and increased costs.
