UKIZ analysis

What exists

Drawn from public sources

The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.

What's missing

UKIZ interpretation · proposal

Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.

What could connect

UKIZ interpretation · proposal

South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.

What could connect elsewhere in Britain

UKIZ interpretation. Places whose capability relates to Cardiff & South Wales, and why connecting them could create more value than either can create alone.

Manchester
Cardiff & South Wales and Manchester both hold Advanced Materials and Creative Industries as a leading strength. Two places strong in the same field is complementary capability, not duplication: the connection worth making is a division of labour between discovery, production and demand.

UKIZ perspective

What this could mean for UKIZ.

Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.

Proposed national missions this ecosystem contributes to
