Company profile

Octric Semiconductors

County Durham compound semiconductor foundry fabricating gallium arsenide, gallium nitride on silicon carbide and indium phosphide wafers for radio frequency, defence, telecoms and space customers.

Company overview

Octric Semiconductors operates the compound semiconductor fab at Newton Aycliffe, County Durham, which the Ministry of Defence bought from Coherent in September 2024. Described by the Government as the only secure UK facility able to manufacture gallium arsenide semiconductors, it provides wafer, die and test outsourcing on its own III-V process platforms, on which customers design their own devices. The site has a 4,800 square metre class 100 cleanroom and a history dating from Fujitsu, then Filtronic and later owners. Its work supports defence radar and communications, telecoms infrastructure, satellite communications and space.
