China's semiconductor talent hunt reveals what sanctions cannot stop

TALENT is harder to sanction than a machine. That is the lesson behind Taiwan's latest crackdown on Chinese firms accused of poaching engineers from the island's semiconductor industry. In March, Taiwan's Investigation Bureau dispatched more than 185 agents to raid 49 locations in Hsinchu and northern Taiwan, questioning 90 people and investigating 11 mainland companies for recruiting Taiwanese engineers without authorisation. The firms, including the electronics manufacturer Huaqin Technology and chip designer SG Micro, allegedly set up shell companies in Taiwan under foreign names and offered inflated salaries to lure specialists from the Hsinchu Science Park.

The operation was not the first. In August last year, Taiwan's authorities launched a similar probe into 16 Chinese firms, searching 70 locations and questioning 120 people. A special task force, established in late 2020, has now handled more than 100 cases of its kind, according to the bureau. The names vary. The pattern does not.

The reason is not hard to see. Taiwan's laws prohibit Chinese investment in sensitive parts of the semiconductor supply chain, including chip design, and require review for others such as packaging. The country amended its National Security Act in 2022 to criminalise the theft and disclosure of "national core key technologies", with penalties for anyone who obtains such secrets on behalf of mainland China. The first official list of protected technologies, published by Taiwan's Executive Yuan in December 2023, includes manufacture of chips at processes of 14nm and below. Chinese firms cannot operate legally in Taiwan's advanced-node ecosystem. They can, however, try to recruit the people who run it.

This is where the talent-poaching story intersects with the broader question of how China plans to catch up in semiconductors. The gap remains formidable. Taiwan Semiconductor Manufacturing Co (TSMC), the world's largest chip foundry, began volume production of its 2nm process in the fourth quarter of 2025. In the second quarter of this year, 2nm chips contributed 3% of TSMC's wafer revenue, and the node had four times as many customer tape-outs as the previous 3nm generation did at the same stage. China's leading foundry, SMIC, can mass-produce 7nm chips, at least two generations behind. It cannot buy the extreme-ultraviolet lithography machines from ASML, the Dutch equipment maker, that are needed for finer nodes. Immersion deep-ultraviolet (DUV) tools, a step below EUV in capability, are also tightly restricted.

To be sure, China is not idle on the equipment front. In July, Reuters reported that a Shanghai-based state-owned company, Aishengna, has begun producing domestic immersion DUV machines. The firm, backed by Shanghai Electric Holding, plans to deliver about five units in 2026 and scale to 20 in 2027. The machines are years from matching ASML's in performance, and require further testing. But their existence gives Chinese foundries a fallback if Western servicing or exports tighten further. The point is not that China will close the equipment gap soon. The point is that it is building a domestic alternative, however imperfect, while pursuing a second, less visible path: acquiring the people who know how to use the machines it cannot legally buy.

Taiwan's approach to this problem has been predominantly law-enforcement. Raids, summons and the occasional prosecution. The strategy is understandable but incomplete. It treats talent poaching as a crime to be punished rather than a market signal to be addressed. The incentive structure, after all, is straightforward. A semiconductor engineer at Hsinchu faces an offer with a substantially higher salary from a Chinese firm that has the resources and, in many cases, the political backing to pay it. Taiwanese companies cannot simply match the bid without eroding their own cost structure. The result is a leak that enforcement alone cannot plug.

The deeper problem is that the raids are a response to symptoms. China's scramble for talent is driven by the same constraint that drives its equipment push: it cannot access the most advanced tools and must therefore seek every available workaround. Taiwan's National Security Bureau has itself warned that Chinese firms use indirect methods - front companies, recruitment schemes, covert channels - to poach engineers and obtain sensitive know-how. The bureau notes that cyber intrusion attempts against Taiwan's government network exceeded 170m in the first quarter of 2026, alongside more than 420 Chinese military aircraft operating near the island. Talent acquisition is not an isolated commercial activity. It is part of a broader campaign of technological absorption.

The better answer is not more raids. It is a mix of retention, compensation and sharper legal tools. Taiwan has made progress: the 2022 National Security Act amendments criminalise the theft of core technologies, and the investigation task force has clearly increased its capacity. But Chiang Min-Yen, a senior analyst at the Research Institute for Democracy, Society, and Emerging Technology, has pointed out that much of Taiwan's semiconductor industry is privately owned and may not fall neatly within the scope of existing regulations. The legal framework still has gaps, and enforcement cannot substitute for a strategy that keeps engineers in Taiwan in the first place.

That strategy would include higher wages at Hsinchu's smaller design houses, stronger equity incentives and immigration policies that make it easier for Taiwanese engineers to work abroad without burning bridges at home. A workforce that feels undervalued will look for a better offer. No amount of prosecution changes that arithmetic. Taiwan could also expand export controls on personnel: requiring clearance for engineers who move to companies linked to mainland China, much as the United States does for sensitive technologies.

The raids are not pointless. They signal that Taiwan will not tolerate the covert absorption of its industrial base. But they are also a reminder of a less flattering truth: when technology is banned, the actors who want it will find another route. Machines can be embargoed. People are harder to keep. Taiwan's advantage in semiconductors will depend less on how many shell companies it shuts down and more on whether it can offer its engineers a reason to stay.

China's talent hunt is not a sign of weakness. It is a sign of strategy. And the response it deserves is not merely a bigger police force.
