Beyond leading-edge fabs
Semiconductor headlines focus on the smallest manufacturing process. Building a leading-edge foundry requires extraordinary, continuing capital and a global customer base. Britain’s credible opportunity is to lead in high-value parts of the chain where it already has knowledge: processor architecture, chip design, photonics, power electronics, compound semiconductors and flexible integrated circuits. These serve data centres, telecoms, automotive, healthcare and packaging.
From design file to product
A brilliant design still needs fabrication, testing, packaging, software and a route into a customer’s system. Young firms can fail in the transition because prototype volumes are too small for favourable manufacturing terms and qualification takes time. Shared tools, pilot lines and packaging capability can remove friction. Long-term agreements with trusted overseas foundries may also be part of resilience; sovereignty does not require pretending the supply chain is entirely domestic.
Specialisation creates power
Flexible chips can add low-cost intelligence to objects that cannot carry a conventional rigid processor. Photonics can move data or sense the physical world efficiently. Compound materials perform well in power and radio-frequency applications. Public support should connect these companies to demanding buyers in energy, defence, mobility, telecoms and healthcare. Britain does not need to win every layer; it needs several layers that global companies cannot easily design around.
