US Chip Ambitions and Arizona's Rise

This episode of Tech Latest from Nik Asia discusses the significant push by the United States to bring advanced chip manufacturing onshore, a goal pursued by both the Trump and Biden administrations. This ambition is rapidly being realized with the substantial involvement of Taiwanese and other Asian suppliers.

TSMC's Arizona Investment and Evolution

• Initial Visit (December 2022): Annie Cheng Tingfang's first trip to Arizona coincided with a landmark event for TSMC's overseas chip plans. The event marked the readiness of the cleanroom for chip-making equipment.
• High-Profile Attendance: The event was attended by CEOs of major tech companies like Apple, Nvidia, and AMD, as well as the head of ASML (a crucial chip equipment maker) and US President Joe Biden.
• Investment Escalation: At the December 2022 event, TSMC announced it would more than double its initial investment from $12 billion to $40 billion. This figure has since grown to $165 billion, with potential for further expansion.
• Environmental Context: Arizona's landscape is characterized by desert, cacti, and rocky mountains. Construction work often starts at 5:00 AM to avoid extreme summer heat.
• Initial Skepticism: A significant concern during the early stages was the lack of a developed supply chain in Arizona to support such a large-scale manufacturing effort.

Intel and TSMC's Dual Presence in Arizona

• Unique Semiconductor Hub: Arizona is unique in hosting two of the world's top chipmakers, Intel and TSMC, both building or planning to build their most advanced chips there.
• Intel's Fab 52: Annie visited Intel's Fab 52 in Chandler, where they are producing 18A (1.8 nanometer) chips. These chips are intended for Intel's latest and next-generation CPUs for laptops and servers.
• TSMC's Landmark Project: Approximately 50 minutes north of Intel's facility, TSMC's massive $165 billion project is marked by a large red crane.
• Construction Scale: On any given day, 5,000 to 6,000 construction workers are on-site, with peak employment reaching 120,000 people.
• TSMC's First Advanced Plant: After four to five years of development, including challenges like COVID-19 lockdowns, labor shortages, and permit delays, TSMC's first plant for advanced chips (for Apple and Nvidia) began production in 2024.
• Current TSMC Operations: Approximately 3,000 employees are already working at the TSMC plant. Construction continues on a second plant, a third plant shell, and a new office building. The entire complex is planned to include eight facilities for chipmaking, packaging, and R&D.
• Economic Impact: The development is spurring significant real estate activity, with developers planning hotels, shopping centers, supermarkets, and housing around the cluster.

Factors Driving Rapid Growth and Sustainability

• US Government Incentives: Policy support from the US government has been a significant factor.
• Customer Demand as the True Driver: Ultimately, demand and actual customer orders are crucial for the sustainability of these investments. As TSMC Chairman C.C. Wei stated, "only big numbers can really get president's attention."
• Challenges for Early Suppliers: Many early suppliers who followed TSMC to Arizona faced significant difficulties. United Integrated Services (UIS), a Taiwanese cleanroom and facility builder, experienced challenges adapting to US operational culture and regulations. UIS President Lie of Lake US described a period of uncertainty, stating, "there was a period when he didn't know how long the dark tunnel would last."
• UIS's Success: Despite initial struggles, UIS has built a strong local team of 380 specialists, hired locally, and taken on greater responsibility. They have identified local subcontractors and established a logistics center.
• Learning Curve and Efficiency: Years of trial and error have led to a better understanding of how to operate efficiently in the US.
• Phoenix City Officials' Learning: City officials have also gained experience in inspecting semiconductor facilities, a process that was initially much slower. For example, approving a small area of electrical transmission took three months initially, compared to a day now.
• The AI Boom: The current AI boom and the massive demand from AI data centers are the primary drivers behind TSMC's commitment to large-scale capacity in the US.
• North American Customer Revenue: In the most recent quarter, 76% of TSMC's revenue came from North American customers like Nvidia, Apple, Microsoft, and Amazon. Nvidia's CEO has personally visited TSMC multiple times to request more wafers.
• Accelerating Infrastructure: The AI infrastructure boom, which appears to be accelerating, provides a strong foundation for Arizona's continued benefit.

Future Expansion and Challenges

• Smoother Future Expansion: TSMC's next phase of expansion in Arizona is expected to be smoother and quicker than the first, which took four to five years. Suppliers are targeting "Taiwan speed" (18 months to two years) for building plants, though they acknowledge the need to adapt to local operations and culture.
• Advanced Node Production: Once the $165 billion project is complete, TSMC aims to produce about 30% of its most advanced chips in the US.
• Potential Chip Renaissance: If Intel's 18A production and future nodes are successful, it could lead to a "chip renaissance" in America.
• Key Challenges:
  • Customer Demand: Actual chip orders remain a critical factor.
  • Skilled Engineers: A shortage of highly skilled engineers is a challenge, as advanced manufacturing requires strict protocols. The potential for advanced humanoid robots to assist in these processes is noted.
  • Cost and Profitability: The overall cost of investment and whether customers are willing to pay a fair price for US-made chips are essential for profitability and sustainability.
• Emergence of Chip Packaging: Chip packaging, historically a less high-tech part of the supply chain and largely outsourced to Asia, is becoming increasingly critical due to AI's need to link different chips for enhanced computing performance. Both Intel and TSMC are building advanced chip packaging plants in Arizona.
• UMC's Involvement: Taiwan's UMC is collaborating with Intel to use older generation plants in Arizona for developing 12-nanometer grade chips. This indicates a move towards producing more mature node chips in the US, potentially for critical applications like defense and aerospace, where customers might pay a premium for localization and security. This production is anticipated around 2027.

Intel's Foundry Business Evolution

• Long-Standing Presence: Intel has had a significant presence in Arizona since 1979, with its Arizona campus being a major R&D and manufacturing hub.
• Market Position: Intel remains the world's largest maker of microprocessors for PCs and servers.
• Internal Needs First: Intel's foundry plans will prioritize serving its internal needs while seeking external clients.
• Operational Efficiency and Yield: Intel's challenge lies in improving operational efficiency, yield, and producing high-quality chips at an economic scale.
• Supplier Openness: Suppliers who have partnered with TSMC are open to serving other chipmakers, including Intel, Micron, Texas Instruments, Global Foundries, Samsung, and SK Hynix, fostering a broader ecosystem.

Broader Trends and Future Outlook

• Increased Confidence in Overseas Expansion: More companies are considering expanding overseas, including in Arizona and other US states like Texas (where Samsung is located).
• Semicon West in Arizona: The semiconductor industry fair, Semicon West, was hosted in Arizona for the first time in October, indicating the region's growing importance. The event saw significant visitor turnout, a contrast to previous years.
• Direct Flights to Phoenix: The introduction of direct flights from Taipei to Phoenix by two Taiwanese airlines starting in December signifies increased business ties and the movement of Taiwanese and Asian businesses into the region.
• Cultural Integration: The opening of a famous Taiwanese steam dumpling place, Din Tai Fung, in Phoenix further illustrates the growing presence and integration of Asian businesses.

Conclusion

Arizona is rapidly transforming into a critical hub for advanced chip manufacturing in the US, driven by a confluence of government policy, massive customer demand fueled by the AI boom, and the strategic investments of global leaders like TSMC and Intel. While challenges related to skilled labor, cost, and customer orders persist, the progress made and the ongoing development suggest a promising future for chip production in America. The emergence of chip packaging and the potential for mature node production for critical applications further diversify and strengthen the US semiconductor ecosystem.
