The Future Compound Semiconductor Manufacturing Hub (CS Hub), was an EPSRC Grant that ran from 2016 to 2024. Its vision was to establish the UK as the primary global research and manufacturing hub for Compound Semiconductor (CS) Technologies by combining and connecting the UK research excellence in CS, with the very best translational facilities and the Compound Semiconductor Catapult to support the UK CS industry and UK industry users of CS. The combined activity provided a path from enabling fundamental research through wafer, device and integrated chip manufacturing research into prototyping, reliability testing and system qualification.
