TSMC Arizona Announces Plans for Third Leading-Edge Fab in Phoenix through $6.6B in Proposed CHIPS Act Funding

TSMC Topping of Second Fab in Phoenix

TSMC announced that the U.S. Department of Commerce and TSMC Arizona have signed a non-binding preliminary memorandum of terms (PMT) for up to US$6.6 billion in direct funding under the CHIPS and Science Act. TSMC also announced plans to build a third fab at TSMC Arizona to meet strong customer demand leveraging the most advanced semiconductor process technology in the United States.

As the company makes progress in completing its first fab and continues construction of its second fab at its Arizona subsidiary, the third fab brings TSMC’s total capital expenditure for the Phoenix, Arizona site to more than US$65 billion, making the site the largest foreign direct investment in Arizona history, and the largest foreign direct investments in a greenfield project in U.S. history.

“The CHIPS and Science Act provides TSMC the opportunity to make this unprecedented investment and to offer our foundry service of the most advanced manufacturing technologies in the United States,” said TSMC Chairman Dr. Mark Liu. “Our U.S. operations allow us to better support our U.S. customers, which include several of the world’s leading technology companies. Our U.S. operations will also expand our capability to trailblaze future advancements in semiconductor technology.”

“We are honored to support our customers who have been pioneers in mobile, artificial intelligence and high-performance computing, whether in chip design, hardware systems or software, algorithms, and large language models,” said TSMC CEO Dr. C.C. Wei. “They are the innovators driving demand for the most advanced silicon that TSMC can provide. As their foundry partner, we will help them unleash their innovations by increasing capacity for leading-edge technology through TSMC Arizona. We are thrilled by the progress of our Arizona site to date and are committed to its long-term success.”

TSMC Arizona’s three fabs are expected to create approximately 6,000 direct high-tech, high-wage jobs, building a workforce that will help to support a vibrant and competitive global semiconductor ecosystem that enables leading U.S. companies to gain access to domestically-manufactured, cutting-edge semiconductor products alongside a world-class semiconductor foundry. According to an analysis by the Greater Phoenix Economic Council, this increased investment in three fabs will create more than 20,000 accumulated unique construction jobs, and tens of thousands of indirect supplier and consumer jobs.

TSMC Arizona’s first fab is on track to begin production leveraging 4nm technology in first half of 2025. The second fab will produce the world’s most advanced 2nm process technology with next-generation nanosheet transistors in addition to the previously announced 3nm technology, with production beginning in 2028. The third fab will produce chips using 2nm or more advanced processes, with production beginning by the end of the decade. Each of the three fabs, like all of TSMC’s advanced fabs, will have cleanroom area approximately double the size of an industry standard logic fab.

TSMC practices green manufacturing and aims to serve as a global standard for eco-friendly corporations with constant innovations in energy efficiency, water conservation, waste management, and air pollution control. TSMC Arizona’s fabs are designed and built with that same global vision and aims to achieve a 90% water recycling rate. The company has started the design phase of building an industrial water reclamation plant with a design goal of achieving “near zero liquid discharge”, bringing nearly every drop of water back into the facility.

In addition to the proposed US$6.6 billion in direct funding, the PMT also proposes to provide TSMC with up to US$5 billion in loans. TSMC plans to apply for U.S. Treasury Department Investment Tax Credits of up to 25% of the qualified capital expenditure at TSMC Arizona. The company remains committed to its long-term financial goals, which are 15-20% revenue compound annual growth rate (CAGR) in USD terms, 53% and higher gross margin, and 25% and higher return on equity (ROE).

All TSMC overseas investment are subject to regulatory approvals in Taiwan as necessary.
