Summary

Semiconductors are in high demand, and developers in the U.S. are answering the call. In addition to multiple chip-fabrication projects completed in the past year, Industrial Info Resources is tracking more than $630 billion worth of U.S. semiconductor projects planned to kick off in the future and $85 billion worth that are presently under construction in the U.S.

An In-Demand Product

Demand for the semiconductors that power the modern world are in great demand, and chip manufacturers are stepping up in the U.S., with hundreds of billions of dollars' worth of semiconductor projects on the table, although not all of these will be built as planned. According to Industrial Info Resources data, there are 13 U.S. semiconductor projects valued at $85 million now under construction and another $632 billion worth of related capital projects planned for the future.

The geography of semiconductor spending, which has large effects on regional labor and power markets, is scattered throughout the U.S. In regard to current, on-the-ground projects, Arizona and Ohio are neck and neck for leading semiconductor investments, garnering around $28 billion each, while Idaho comes in a close third place thanks to a single $25 billion project.

Active Construction

Those projects giving the states their spending leads come from Taiwan Semiconductor Manufacturing Company (TSMC) in Arizona, Intel in Ohio and Micron Technology in Idaho. All of the companies are benefitting from funding from the CHIPS and Science Act passed in 2022.

TSMC in Arizona

Well before receiving the CHIPS Act funding, however, TSMC had broken ground on the first fabrication facility (fab) of a semiconductor manufacturing hub that the company is constructing in Phoenix, Arizona. That first fab began started operating in late 2024 and early 2025, but TSMC didn't stop there. Another two fabs with a combined investment value of $24 billion are under construction in Phoenix, with startup dates of 2028 and 2030. Subscribers to the Industrial Info Resources Global Market Intelligence (GMI) Industrial Manufacturing Project Database can learn more by viewing the related project reports. Industrial Info Resources is tracking another $330 billion that TSMC is considering dropping on the site, including three additional fabs and expansions to existing facilities.

Intel in Ohio

Intel also received CHIPS and Science Act funding and is concentrating its construction in New Albany, Ohio, just northeast of Columbus. There, the company is investing an estimated $28 billion on Project Cardinal and Project Dragonfly, two semiconductor fabs that are expected to come online in 2030 and 2032, respectively. Each fab measures about 1.4 million square feet and includes equipment such as air-separation units, etching and polishing lines, cleanrooms, and more. The chips will be used across a range of applications, including vehicles, data centers and electronic devices.

Ohio

New Albany, Ohio, is home to about $24 billion worth of data center projects. Industrial Info Resources is tracking 13 data center projects under construction in New Albany valued at $7.25 million, and another $14.1 billion worth in the planning and engineering stages. These 40+ projects don't represent 40 different sites, but rather fewer locations that house multiple data halls. Meta Platforms is at work on five data center buildings in the New Albany area, with plans for more. Another big player, Amazon Web Services, is at work on a $600 million data center project in New Albany, with plans calling for up to 11 additional buildings carrying a price tag of $5.2 billion.

Other companies are lining up for their places in New Albany or are already underway with construction there. Vantage Data Centers is constructing $1.28 billion of data center projects in New Albany. Subscribers can learn more by viewing the related project reports.

Micron in Idaho

Micron Technology's memory chips are integral for storing digital data in applications such as computers, smartphones, data centers and artificial intelligence systems. On June 12 last year, Micron unveiled plans for $200 billion worth of spending-- $150 billion for semiconductor manufacturing and another $50 billion for research and development. Like TSMC, Micron already was at work on a new fab building in Boise when it received funding support from the CHIPS and Science Act. That $25 million, 600,000-square-foot fab is well into construction and expected to begin rolling out dynamic random-access memory (DRAM) chips in 2027.

Micron also is putting its investment funding toward a big project in Clay, New York, where it plans to break ground on a fab building this year, followed by up to three more buildings. The first fab is expected to be completed in 2030.

Future U.S. Fab Construction

Semiconductor fabs often are multibillion-dollar undertakings, and developing moving them from the planning table to active construction requires lots of moving pieces to be accounted for, including funding, power availability, multiple air and land permits, as well as labor availability.

For that reason, which of the $632 billion in semiconductor projects in the planning and engineering stages will actually get moving relatively soon often is hazy. TSMC's additional Arizona projects and Micron's New York projects push those two states into the lead for future U.S. semiconductor project development, with Texas coming in a distant third place. Texas' position comes largely from Texas Instruments' planned work in Sherman, where Industrial Info Resources is tracking two fabs that were completed last year at cost of $13.5 billion, and another two buildings that are planned, carrying a combined price tag of $15.9 billion.

A potential $25 billion expansion of Micron's Idaho plant puts that state just below Texas for future semiconductor spending.

Key Takeaways

Industrial Info Resources is tracking $85 billion worth of U.S. semiconductor projects under construction and another $632 billion in the planning and engineering stages.
• Arizona, Ohio and Idaho are garnering the most on-the-ground semiconductor spending.
• New Albany, Ohio, where Intel is constructing two semiconductors fabs is also a hotspot for data center construction.
