Exclusive: Made in Britain, enabled by Taiwan — the hidden dependencies behind critical chips

The UK's reliance on Taiwan, China for extreme-environment chip fabrication exposes a critical structural vulnerability in Europe's semiconductor strategy. While design capabilities are localized, the manufacturing of radiation-hardened and high-temperature components remains tethered to external mature-node capacity. This dependency creates a geopolitical chokepoint, transforming supply chain resilience into a national security imperative. Compliance costs are rising as firms navigate complex regulatory landscapes to mitigate single-source risks. Competitors are strategically diversifying their foundry partnerships to hedge against geopolitical premiums, accelerating a shift towards redundant, multi-regional production networks. Over the next 12-24 months, expect a surge in capital expenditure aimed at establishing sovereign manufacturing capabilities in Europe. However, the high barrier to entry for advanced packaging and specialized process nodes means immediate self-sufficiency is unlikely. This trend signals a fundamental reconfiguration of global tech power, where supply chain geography becomes as critical as technological innovation.
