Bangkok Post – Arizona aspires to be chip off the Taiwanese block

[ad_1]

Contrary to expectations, the Taiwan Semiconductor Manufacturing Company (TSMC) semiconductor plant in Arizona is reportedly on track to meet its 2025 production targets. This announcement poses a challenge to the many observers who predicted that the effort to bring chip manufacturing back to the United States would fail. What went right this time?

Scepticism surrounding the Arizona plant stemmed from the belief that chip manufacturing benefits heavily from learning-by-doing and dynamic economies of scale, both of which give incumbents a significant cost advantage. That is how TSMC maintains its dominance in cutting-edge technologies, producing around 92% of the world's most advanced logic chips at its Taiwan plant.

It was this high concentration that prompted calls to diversify production in the interest of ensuring supply-chain resilience. But the same learning-by-doing imperative is an obstacle for new entrants, casting doubts on projects like the one in Arizona. Moreover, with anti-immigration sentiment on the rise, concerns about America's ability to attract skilled labour added to the pessimism.

Yet the gloomy predictions turned out to be overstated. In new research, my colleagues and I find that in semiconductors, learning-by-doing is not as technology-node-specific as it is firm-specific. Thus, TSMC's advantage isn't necessarily in producing advanced chips more efficiently but in transferring its knowledge and expertise across different technologies. That means its success could well be replicated in other locations, as long as new plants can build on the Taiwanese parent's experience rather than starting again from scratch.

Another important factor is the cross-border spillover of knowledge. The same research finds substantial spillovers in the transmission of learning across borders. While the exact mechanisms are unclear, foreign technology transfers -- including through foreign direct investment and cross-border recruitment of skilled professionals -- are likely to play a significant role.

Moreover, since the semiconductor supply chain is structured on the "fabless-foundry" model (whereby chip design companies outsource chip fabrication), it, too, facilitates knowledge transfers between countries. Chip design and manufacturing involve close collaboration between buyers and manufacturers around the world, with buyers often a major player in the dissemination of practical knowledge.

These beneficial cross-border knowledge spillovers suggest that government support alone cannot guarantee success in an industry. Taiwan and South Korea owe their dominance in chip manufacturing not only to significant government subsidies, but also to the advantage of access to foreign advanced technologies.

In fact, a similar pattern appears in China's far more successful industrial policy for the automobile sector, where joint ventures between domestic firms and more technologically advanced foreign manufacturers proved instrumental. As with semiconductors, collaboration between firms in different countries stands out as the main driver of technology and product-quality improvements.

Such cross-border learning spillovers have three big implications for current policy. First, the US does indeed stand a strong chance of catching up with Taiwan in semiconductor manufacturing, given the close cooperation between the two countries and America's leading position in research and chip design. Second, efforts to slow China's progress in semiconductors are likely to succeed, considering that US export restrictions have effectively cut China off from foreign advanced technology.

Lastly, other countries looking to become major players in the semiconductor industry (such as India) are dependent on US technological leadership. No matter how much financial support these countries provide, they are unlikely to succeed without US technological backing. An industrial policy that might work for the US, the technology leader, won't necessarily work for others.

The key takeaway is that the US remains in the driver's seat. With its technological leadership and scale, it is poised to meet its semiconductor policy goals: strengthening supply-chain resilience and weakening China's position. Still, one must ask whether these objectives are worthwhile.

In recent years, the US has remained on top by pushing others down. Yet, as Vice President Kamala Harris argued at the recent presidential debate: "The true … leader actually understands that strength is not in beating people down, it's in lifting people up." This applies not only to people but also to countries. ©2024 Project Syndicate
