TSMC adds Arizona packaging plant
- TSMC plans to open a chip packaging plant in Arizona by 2029, expanding U.S. backend capacity beyond wafer fabs. (reuters.com) - Reports say TSMC is investing about $165 billion in the U.S. for five new fabs and two advanced packaging facilities.

TSMC plans to open a chip-packaging plant in Arizona by 2029, adding a final assembly step that its U.S. chip site did not yet have. (finance.yahoo.com) Chip packaging is the stage where separate pieces of silicon are connected into one finished processor, and it has become a choke point for artificial-intelligence chips from companies such as Nvidia. Reuters reported the Arizona facility would reduce the need to send U.S.-made chips back to Taiwan for that work. (money.usnews.com) TSMC had already said in its January 15, 2026 earnings materials that it was applying for permits to build its first advanced packaging plant in an existing Arizona facility. The company did not give a startup date then; the new target is by 2029. (investor.tsmc.com, economictimes.indiatimes.com) The Arizona move extends a much larger U.S. buildout. TSMC said in March 2025 that it intended to raise its total U.S. investment to $165 billion, including three additional wafer fabs, two advanced packaging facilities and an research-and-development center. (pr.tsmc.com) TSMC’s Arizona site is already producing chips. The company says its first fab began high-volume production on 4-nanometer technology in the fourth quarter of 2024, while its second fab is targeted for volume production in the second half of 2027. (tsmc.com) That sequence matters for U.S. customers because a domestic fab without domestic packaging still leaves a key manufacturing step overseas. TSMC said its U.S. advanced packaging investment would help complete a domestic artificial-intelligence supply chain. (pr.tsmc.com) The packaging push also tracks where demand is strongest. On its January 2026 earnings call, TSMC said it expected 2026 capital spending of $52 billion to $56 billion as artificial-intelligence demand stayed strong. (investor.tsmc.com, finance.yahoo.com) By 2029, TSMC is aiming for Arizona to do more than etch chips onto wafers. It wants the site to turn them into finished computing parts closer to the U.S. companies buying them. (finance.yahoo.com, tsmc.com)
