Semiconductor talent migration reveals global chip supply chain fractures and China’s strategic R&D gaps
Original framing: “Chip prodigy Da Bo returns to China after his role in TSMC’s 3nm plant in Japan” — South China Morning Post
The 3nm process node represents a breakthrough in extreme ultraviolet (EUV) lithography, but its scalability is constrained by material science challenges (e.g., photoresist degradation). China’s lag in EUV technology is a direct result of US export controls on ASML’s machines, forcing reliance on older 7nm and 5nm nodes. The migration of talent like Da Bo reflects a brain drain from China’s underfunded public research institutions to better-resourced foreign labs.
Da Bo’s migration from Japan to China epitomizes the global semiconductor industry’s fragmentation, where geopolitical tensions and structural inequities shape innovation pathways.
The narrative of individual genius obscures the role of state-led industrial policy in Japan, the US-led export controls that constrain China, and the labor exploitation embedded in supply chains. Historical precedents, such as the US-Japan semiconductor alliance of the 1980s, reveal how technological dominance is as much about power as it is about engineering. Indigenous knowledge systems, like Japan’s 'monozukuri' tradition, and marginalized voices, such as factory workers and women engineers, offer alternative models for a more equitable and resilient semiconductor ecosystem. The path forward requires not just talent repatriation, but systemic reforms: open R&D consortia, decentralized hubs, ethical labor practices, and open-source hardware to break the cycle of dependency and exclusion.
