Semiconductor Supply Chains Are Shifting Again
The semiconductor supply chain was the twentieth century’s most efficient machine and the twenty-first’s most obvious vulnerability. A handful of firms and places came to dominate each critical step: design in the United States, extreme ultraviolet lithography in the Netherlands, advanced fabrication concentrated in Taiwan and South Korea. Governments that once celebrated the efficiency now spend heavily to change the geography, and the map is shifting, slowly, expensively and incompletely.
The money is real. Subsidy programmes in the United States, Europe, Japan and India run to hundreds of billions of dollars in loans, grants and tax credits, and factories have followed: fabrication plants rising in Arizona, Saxony, Kyushu and Gujarat, alongside expansions across South-East Asia for packaging and testing. Reporting by Reuters on the build-out documents both the scale and the friction: construction delays, shortages of skilled technicians and the stubborn economics that made concentration attractive in the first place. Our front page tracks the shift because chips now sit underneath every other technology story, from AI to electric vehicles.
What Moves Easily, and What Does Not
Not all stages relocate equally. Mature-node chip production, the workhorse technology in cars and appliances, diversifies fastest. Leading-edge fabrication, where a single plant costs upwards of twenty billion dollars and depends on an ecosystem of chemical, gas and equipment suppliers refined over decades, moves at glacial pace. Advanced packaging, suddenly strategic in the AI era, sits between the two, and is attracting investment precisely because it is buildable in years rather than decades.
Export controls overlay the commercial map. Restrictions on advanced chips and the equipment to make them, aimed principally at China, have accelerated a parallel Chinese effort in domestic tools and mature capacity, while pulling allied supply chains tighter. The BBC’s technology reporting has charted the resulting bifurcation: two ecosystems, overlapping but increasingly distinct, with companies redesigning products to sit on the right side of shifting rules.
Resilience Has a Price Someone Must Pay
Duplicating the world’s most complex supply chain was never going to be cheap, and the bill arrives as higher chip costs, subsidy competition and pressure on the very firms being courted. Manufacturers ask, reasonably, who pays the premium for resilience in peacetime, when buyers reward the lowest price. Governments answer with procurement, stockpiles and incentives; markets answer by quietly dual-sourcing critical components where the pandemic taught them the cost of a single source.
Full self-sufficiency is a fantasy no serious planner pursues; the materials and expertise are too widely scattered. The realistic goal is balance: no single point of failure for the chips that run power grids, hospitals, vehicles and defence systems. Measured against that goal, the shift under way is meaningful but unfinished, with the hardest, most concentrated steps still concentrated.
The Talent Bottleneck Nobody Subsidised Enough
Ask plant managers what limits the great rebuild and the answer is rarely money; it is people. A modern fabrication plant needs process engineers, equipment technicians and cleanroom operators in the thousands, trained over years, in regions that often lack an existing semiconductor workforce. Arizona colleges have built rapid technician programmes with manufacturers; German and Japanese regions are retraining automotive workers whose skills translate surprisingly well. Immigration policy, rarely mentioned in chip strategies, quietly determines whether new plants open staffed or short-handed. The lesson generalises: industrial strategy is workforce strategy, and the countries treating training as infrastructure, funded early, designed with employers, are the ones whose subsidised factories are likeliest to open on schedule and run at yield. Further reporting on this subject is collected in our archive, for readers who want the background behind today’s developments.
Supply chains are strategy written in factories. The current redrawing will take a decade to complete and will be judged by a crisis nobody can schedule. Until then, the cranes over new fabrication plants on three continents are the most honest progress report available, and they are, at last, numerous.
