South Wales: a compound semiconductor supply chain in one region

How university research in compound semiconductors became a regional cluster covering epitaxy, fabrication and packaging.

Where it started
Cardiff and Swansea university research groups working on compound semiconductor materials and devices.

The journey

Research → IP → company → capital → customers → scale → export.

  1. Research

    University research groups in compound semiconductor materials, devices and photonics.

  2. IP

    Device and process intellectual property developed alongside industrial partners rather than in isolation.

  3. Company

    Fabrication, epitaxy and packaging businesses established in the region, forming a connected supply chain.

  4. Capital

    Capital intensity is high; funding has combined corporate investment with public co-investment. Detailed round-level evidence is an open gap.

  5. Customer

    Automotive, communications, defence and power electronics customers, largely outside Wales.

  6. Scale

    Cluster-level scale rather than a single dominant company, supported by shared facilities.

  7. Export

    Output largely serves international supply chains.

What the ecosystem contributed

What the ecosystem contributed

  • Two research-intensive universities within one region
  • Shared, capital-intensive fabrication facilities
  • Industrial partners located close to the research base
  • Government designation and place-based programme support

What almost broke

  • Capital intensity: semiconductor facilities cannot be funded on venture timelines alone
  • Ownership: sustaining UK ownership through consolidation is an ongoing question
