Following its strong second-quarter financial results, TSMC confirmed plans to increase its investment in Arizona to a total of $265 billion, adding another $100 billion to its expansion programme. The move reflects growing demand from customers seeking advanced chips to power artificial intelligence applications.
TSMC Chief Financial Officer Wendell Huang said the company remains encouraged by the progress of its Arizona operations and believes the demand outlook remains strong.
“We will continue to invest,” Huang said, while expressing appreciation for support from the U.S. government.
He added that the company continues to see “strong demand — multi-year structural demand” from customers.
As the primary manufacturer of some of the world’s most advanced AI processors and a key supplier to companies such as Nvidia, TSMC has become a major indicator of the health of the global semiconductor industry. Its rapid expansion, increasing capital spending, and strong profit margins highlight the growing importance of AI-related chip production.
Arizona Expansion Reaches New Phase
TSMC’s first Arizona fabrication facility, known as a fab, is already operational and has achieved production results comparable to the company’s leading facilities in Taiwan, according to Huang.
The second fab is expected to begin equipment installation soon, while construction continues on a third facility. Preparatory work has also started on a fourth fab and the company’s first advanced packaging facility in the region.
Once completed, TSMC’s Arizona operations are expected to include 12 fabrication and advanced packaging facilities alongside a research and development centre.
However, Huang acknowledged that the expansion is not without difficulties. The company faces practical limitations, including a shortage of available construction workers and infrastructure challenges.
“There are physical constraints — the number of construction workers available, the infrastructures available,” Huang said. “We’ll work closely with the government to solve these issues.”
The company is also continuing major investments in Taiwan, where it plans to build 13 advanced manufacturing and packaging facilities over the coming years.
Huang explained that Taiwan remains essential for the development of the company’s most advanced technologies because of the close relationship between research and manufacturing teams.
“When you ramp the most leading-edge technologies, you need very close collaboration between the R&D and operation functions,” he said. “It has to be in Taiwan. And after it stabilizes, then we can consider transferring overseas.”
Geopolitical Pressure and Export Challenges
Despite its ambitious growth plans, TSMC continues to navigate geopolitical tensions between the United States and China, particularly around restrictions on advanced semiconductor exports.
The company has faced scrutiny over whether one of its chips was later used in a Huawei artificial intelligence processor, leading to a U.S. export control investigation. Reports have suggested TSMC could face a significant financial penalty if the matter results in a settlement.
Huang directed questions about the investigation’s status to the U.S. government but said TSMC regularly reviews and strengthens its internal export control systems.
“I have to say there is only so much we can do in terms of complying with all the rules and regulations, but when the customers sell to customers, they sell to customers,” he said.
“At some point in time, you lose the visibility. That’s the reality.”
Competition Intensifies in the AI Chip Race
While TSMC remains the dominant force in advanced semiconductor manufacturing, competitors are working to close the gap.
Companies such as Samsung Electronics and Intel are increasing their efforts in advanced chip production, with Intel receiving significant support from the U.S. government as part of efforts to expand domestic semiconductor manufacturing.
At the same time, concerns about whether the current AI boom can justify massive infrastructure investments have returned among investors. TSMC shares declined despite the company reporting record results, although the stock has still recorded strong gains over the year.
Huang said TSMC remains confident in its ability to maintain its leadership position.
“We do not intend to leave anything on the table,” he said. “Our competitors are good, but we are even better.”
With AI demand continuing to reshape the semiconductor industry, TSMC’s ability to scale production, manage geopolitical risks, and overcome operational challenges will determine whether it can maintain its position at the centre of the global chip race.
