US Semiconductor Boom: Getting Bigger

Updated: Dec 15, 2022

The Taiwan Semiconductor Corporation (TSMC) announced (December 6) that it will build a second semiconductor chip manufacturing facility at the same location of its first US facility north of Phoenix, Arizona.

The first facility will initially produce the company’s 5-nanometer chips using the company's new and advanced manufacturing process (i.e., "N4"). The facility is expected to be fully operational in 2024 and create 2,000 TSMC jobs.

The second facility will produce the company's future 3-nanometer chips, among the most advanced chips, increasing the number of TSMC jobs to 4,500. The company says that the additional facility will take the company's total planned US investment to $40 billion, and is expected to be fully operational by 2026.

This TSMC announcement could be the final big US semiconductor manufacturing announcement before the Commerce Department begins its formal process early next year in support of the distribution of more than $50 billion in funding intended to bolster US domestic semiconductor manufacturing growth. The funding that was provided under the 2022 CHIPS and Science Act. Virtually every major semiconductor company operating in the United States is likely to seek a portion of the funds.

Other Significant Announced Facilities

Outside of the TSMC Arizona facilities, here are the other key facilities planned or under construction around the United States:

Intel Semiconductor Production Facilities (Arizona & Ohio)

Two new chip production facilities with a $20 billion investment on an existing Intel campus in Chandler, Arizona. Production at the new facilities is expected to begin in 2024, and Intel will add 3,000 jobs. In Ohio, Intel will add two new production facilities near Columbus, Ohio, with a $20 billion investment and creating 3,000 Intel jobs. Intel indicates that the Columbus location could eventually be expanded to 8 production facilities. Production at the initial facilities could come online as soon as 2025.

Micron Memory Production Facilities (Idaho & New York)

Two new facilities. A $15 billion investment for a new semiconductor production facility in Boise, Idaho, producing DRAM memory chips. Initial production is expected to come online in 2025 with 2,000 Micron jobs. The company will invest $20 billion over the next ten years to design and build a memory chip “megafab” production facility in New York. The investment could increase to $100 billion over twenty years, and add a total of 9,000 Micron jobs. Construction of the initial megafab facility is expected to begin in 2024.

Texas Instruments Production Facilities (Sherman, Texas)

As many as four new semiconductor production facilities with a $30 billion investment in Sherman, Texas, producing the company’s new 300-millimeter semiconductor wafer. All facilities are expected to produce 3,000 new Texas Instruments jobs. The first facility is expected to come online in 2025.

Samsung Production Facility (Taylor, Texas)

A new production facility with a $17 billion investment for the production of “advanced logic semiconductor solutions” including for mobile, 5G, high-performance computing (HPC) and artificial intelligence (AI). Initial production is expected by the second half of 2024, and will employ 2,000 Samsung workers.

GlobalFoundries Second NY Facility (Malta, New York)

GlobalFoundries says that it plans on building a second production facility near its existing Malta, New York campus, though this may depend in part up receiving US Federal subsidies under the CHIPS and Science Act. Separately, Qualcomm announced that it would increase its planned chip purchasing from GlobalFoundries' Malta facility to $4.2 billion as part of a $1 billion production expansion plan at the existing location.

Skywater Technology (West Lafayette, Indiana)

Invest in a $1.8 billion semiconductor R&D and production facility on the Purdue University campus. The company claims that the facility will help Skywater "accelerate domestic semiconductor capabilities, ensure IP security and support a more resilient and comprehensive supply chain, providing powerful competitive advantages for its U.S. government and commercial customers."


The Semiconductor Industry Association published a complete list of semiconductor and related semiconductor projects across the United States that have been announced and/or are underway.
