TSMC Announces $100 Billion Investment in U.S. Semiconductor Expansion: 3 New Fabs and 2 Advanced Packaging Facilities

March 4, 2025 – Taiwan Semiconductor Manufacturing Company (TSMC) has announced plans to increase its U.S. investment by an additional $100 billion, bringing its total investment in the country to $165 billion. This funding will support the construction of three new semiconductor fabs, two advanced packaging facilities, and a major R&D center in the United States.

Previously, TSMC’s U.S. projects primarily focused on wafer fabrication and design services, but this new investment expands into advanced back-end manufacturing, enhancing TSMC’s capabilities in packaging and chip integration.

TSMC’s U.S. Expansion: A Major Semiconductor Push

TSMC Chairman and CEO C.C. Wei stated:

"We are committed to strengthening semiconductor manufacturing in the United States. By adding an additional $100 billion in investment, TSMC will establish a total of six semiconductor fabs and two advanced packaging facilities, ensuring a robust supply chain for AI, high-performance computing (HPC), and automotive applications."

This massive investment underscores TSMC’s strategic intent to position itself at the forefront of the U.S. semiconductor industry, meeting growing demands for AI, HPC, and next-gen consumer electronics.

Advanced Packaging: Strengthening the AI and HPC Ecosystem

The location of the three new fabs and two packaging facilities has yet to be confirmed, but given TSMC’s existing presence in Arizona, experts speculate the new sites will be strategically placed in semiconductor hubs to leverage existing supply chains, talent pools, and infrastructure.

TSMC + Amkor: A Strong Advanced Packaging Partnership

TSMC and Amkor signed an agreement for Amkor to provide advanced packaging and testing services for TSMC’s Arizona fabs.

Amkor is currently expanding its packaging capacity in Arizona to meet the growing demand from AI and HPC chip manufacturers.

Will TSMC’s new packaging plants compete with Amkor?
Unlikely. Industry analysts believe that TSMC and Amkor will continue to work together, given the massive demand for advanced packaging.

AI & HPC Demand Driving Advanced Packaging Expansion

Tech giants like Amazon AWS, Microsoft, Google, and Meta require cutting-edge chip packaging for cloud computing, AI model training, and data centers.

NVIDIA, AMD, and Intel rely on CoWoS and SoIC technologies to integrate high-performance CPUs, GPUs, and memory stacks.

TSMC’s "Foundry 2.0" Strategy: Integrated Wafer + Packaging Model

TSMC integrates chip fabrication with packaging & testing for a seamless chip production ecosystem.

With Moore’s Law slowing down, advanced packaging is crucial for continued performance improvements.

GlobalFoundries Joins the Race

GlobalFoundries is investing $575 million to establish an advanced packaging and testing facility in New York.

Supported by $1.5 billion in U.S. CHIPS Act funding, GlobalFoundries is expanding silicon photonics and AI chip manufacturing.

ASE Technology and Amkor Scaling Up

ASE Technology (Siliconware Precision) and Amkor are ramping up their advanced packaging capabilities to support TSMC's overflow orders.

Amkor’s Vietnam plant is doubling its capacity to support SiP and HBM integration.

Advanced Node Expansion: TSMC’s U.S. 2nm Roadmap

TSMC Arizona Fabs: Key Developments

Fab 1: 4nm (N4P) production started in Q4 2024
Fab 2: 3nm (N3) installation in 2026, production by late 2027
Fab 3: 2nm (A16) construction begins mid-2025, production in 2028

New $100 Billion Investment: Next-Gen Nodes (2nm & Beyond)

The three new fabs will focus on 2nm and future process nodes, expected to begin production between 2029–2030.

TSMC Japan Fab Delay: Prioritizing U.S. Expansion

TSMC’s Japan plant in Kumamoto was originally set to break ground in early 2025 but has now been pushed to later in the year.

Industry experts believe TSMC is prioritizing its U.S. investments over Japan's expansion.

Taiwan 2nm Capacity Surge

TSMC’s Hsinchu and Kaohsiung fabs are expected to ramp up 2nm production to 50,000 wafers per month by the end of 2025.

If demand remains strong, capacity could reach 80,000 wafers per month.

Intel’s Struggles in Advanced Manufacturing

While TSMC aggressively expands in the U.S., Intel is facing challenges in its Ohio mega-fab project:

Intel's $100 billion Ohio facility, announced in 2022, has been delayed from 2025 to 2030.

The second phase is pushed back to 2032 due to capital expenditure concerns.

Intel’s 18A Process: Catching Up in the AI Race

Intel claims its 18A process (1.8nm) is ready for production in H2 2025.

Key partners like Microsoft, Amazon, NVIDIA, and Broadcom are evaluating Intel’s process nodes.

Intel expects 18A to close the gap with TSMC’s N2 process.

Intel’s High-NA EUV Gamble

Intel has become the first semiconductor company to deploy ASML’s High-NA EUV lithography tools.

ASML’s new tools are expected to significantly reduce patterning complexity, improving yield and performance.

Can Intel regain its manufacturing lead?
Intel’s ribbonFET GAA transistors and PowerVia backside power delivery are promising, but TSMC remains ahead in ecosystem partnerships.

The Future of Semiconductor Manufacturing

TSMC’s U.S. Strategy: Building a Comprehensive Supply Chain

With $165 billion invested in the U.S., TSMC is transforming the region into a global semiconductor hub.

Six wafer fabs + two advanced packaging facilities = A fully integrated chip manufacturing ecosystem.

Stronger supply chain partnerships with Amkor, ASE, and GlobalFoundries.

Direct competition with Intel’s foundry ambitions.

Key Takeaways

TSMC’s $100 billion expansion cements its position as the global semiconductor leader.
Advanced packaging is critical for AI and HPC markets – CoWoS and SoIC integration will shape next-gen computing.
Intel faces major delays but hopes its 18A and High-NA EUV technologies can close the gap.
GlobalFoundries, ASE, and Amkor are expanding to support growing demand.

What’s Next?

With the AI semiconductor boom accelerating, expect TSMC, Intel, and GlobalFoundries to push the boundaries of process technology and chip packaging.

Who will lead the next generation of chip manufacturing?
The race is on.
