TSMC to Open Chip Packaging Plant in Arizona by 2029, Executive Announces

• Construction has begun on TSMC's first U.S. advanced packaging facility within an existing Arizona site, targeting operations before 2029
• Modern AI chips from companies like Nvidia require multiple chips combined using advanced packaging, which has become a supply bottleneck
• TSMC currently manufactures chips for Apple and Nvidia in Arizona, but those chips must return to Taiwan for packaging, creating logistical inefficiencies

TSMC to Open Chip Packaging Plant in Arizona by 2029

Key Development:

Taiwan Semiconductor Manufacturing Co. (TSMC) will establish an advanced chip packaging facility in Arizona by 2029, according to company executive Kevin Zhang, deputy co-chief operations officer. Construction has already begun at an existing Arizona facility.

Strategic Importance:

The plant will focus on CoWoS and 3D-IC packaging technologies, critical capabilities for modern AI chips. These advanced packaging methods involve combining multiple chips into single units—a process that has become a supply bottleneck for companies like Nvidia. Currently, chips manufactured at TSMC's Arizona factory must be shipped back to Taiwan for packaging, creating inefficiencies.

Market Context:

Major tech companies including Apple and Nvidia already source chips from TSMC's Arizona operations. The packaging plant aims to create a more complete domestic supply chain in the United States. TSMC is also exploring partnerships with Amkor Technology, which announced plans last year to work with Apple and Nvidia on U.S.-based packaging solutions.

Implications:

This expansion represents a significant step in reshoring critical semiconductor manufacturing to the U.S. The move addresses supply chain vulnerabilities and responds to growing demand for AI chips, where advanced packaging has become as crucial as chip fabrication itself. Zhang emphasized TSMC's commitment to "aggressively expanding" capabilities and establishing "a very diverse manufacturing footprint."

Timeline:

While TSMC previously applied for construction permits without specifying a timeline, the 2029 target date now provides clarity for customers and investors planning long-term supply chains. Technology discussions with Amkor remain ongoing, suggesting flexibility in the final operational structure.
