Key Insights:

• TSMC’s $65 billion investment enhances U.S. semiconductor capabilities, targeting 2nm chip production in Arizona by 2028 amid global supply concerns.
• Advanced chip manufacturing in the US faces challenges, requiring intricate assembly and global partnerships despite onshoring efforts.
• Despite TSMC’s expansion, complete US semiconductor self-sufficiency remains challenging due to complex global supply chains and technology integrations.

The Taiwan Semiconductor Manufacturing Company (TSMC) has announced a significant expansion in the United States with a planned investment of $65 billion. This initiative aims to establish advanced chipmaking facilities in Arizona, which will start producing 2-nanometer (nm) chips by 2028, an upgrade from the previously planned 3nm chips. This move is part of a broader strategy under the U.S. 2022 Chips and Science Act, which seeks to bolster domestic production of critical semiconductor technologies.

The construction of these facilities in Arizona is a response to growing security concerns over the supply chains of essential technologies, particularly those used in AI applications. TSMC’s commitment also aligns with the U.S. government’s objective to enhance its semiconductor manufacturing capabilities, ensuring that by the end of the decade, the U.S. will produce about 20% of the world’s most advanced chips. This effort involves substantial financial incentives, including $6.6 billion in grants and up to $5 billion in loans offered to TSMC.

Strategic Balancing and Customer Relationships

As TSMC increases its footprint in the U.S., it faces the challenge of maintaining its highly profitable business model while meeting the demands of key customers like Nvidia. This strategic expansion necessitates a delicate balance, as TSMC must manage customer preferences for manufacturing locations while maintaining its operational flexibility and capacity allocation strategies. Historically, TSMC has achieved gross profit margins exceeding 50% due to its efficient capacity management and high yields in chip production.

In an unprecedented move for the company, TSMC is allowing clients like AMD and possibly Nvidia to choose where their chips are fabricated. This decision could potentially shift some chip production from Taiwan to the U.S., specifically to the new Arizona facilities. Such arrangements, however, are likely to involve negotiations over pricing premiums or upfront deposits, reflecting the logistical complexities and costs associated with specific plant allocations.

Challenges in Complete Onshoring of Chip Manufacturing

Despite these significant investments, the complete onshoring of chip manufacturing processes in the U.S. faces several obstacles. Advanced semiconductor production involves not just the fabrication of the chips but also their assembly and testing, processes that are currently spread across various global locations. 

For instance, while TSMC can manufacture chips, the assembly of different chip types, such as those combining logic and memory components, often takes place in Asia.

Moreover, other components like high-bandwidth memory chips, crucial for AI applications, are still predominantly manufactured in South Korea by companies like SK Hynix. Although SK Hynix has plans to build an advanced packaging facility in Indiana, the memory chips themselves will continue to be produced in South Korea. Such complexities highlight the challenges of fully integrating the semiconductor supply chain within U.S. borders.

Competing Global Interests and Future Directions

Samsung Electronics, another major player in the semiconductor industry, is also expanding its operations in the U.S., with plans to establish an advanced packaging facility in Texas. This move could offer a more integrated solution for companies needing both logic and memory chips. However, industry experts still need to be convinced that customers will switch from TSMC to Samsung due to differences in technology mastery.

As these developments unfold, the global semiconductor landscape continues to evolve, influenced by technological advancements and geopolitical pressures. The efforts of companies like TSMC and Samsung to expand their U.S. operations are crucial steps toward mitigating risks associated with the global supply chain for critical technologies. 

However, the full realization of a completely domestic semiconductor manufacturing ecosystem in the U.S. remains an ambitious goal, fraught with technical, economic, and strategic challenges.
