Compound Semiconductor Centre

Organisation Information

Founded in 2015, The Compound Semiconductor Centre (CSC) is a joint venture between IQE plc and Cardiff University to underpin the creation of a unique capability for emerging technologies based on Compound Semiconductor (CS) materials.

CSC is co-located with IQE plc in St Mellons, Cardiff, UK, in facilities which house 15 Compound Semiconductor MOCVD (Metal Organic Chemical Vapour Deposition) volume reactors and 5 CVD Si/Ge deposition reactors. This collective capability represents an investment of in excess of £35M in epitaxial growth and characterisation equipment.

CSC provides a complete capability chain from research and development through product and process innovation to large-scale manufacturing via IQE’s global facilities.

Since 2016, CSC has secured twenty-seven collaborative research projects (2021) with total value of >£80M across all partners.

With a focus on:

  • High performance opto-electronic components for telecommunications; and datacommunications applications;
  • Infra Red detector structures for imaging and sensing applications;
  • Structures for RF and Power electronics applications; and
  • Vertical Cavity Surface Emitting Laser (VCSEL) epitaxial technology;

CSC offers:

  • Collaborative research and innovation services based on the development of novel CS materials and structures;
  • Commercial supply of ‘early-stage’ CS epitaxial materials and structures based on GaAs (Gallium Arsenide), InP (Indium Phoshide) and GaN (Gallium Nitride) material systems; and
  • Brokerage to CS device chip-scale fabrication and packaging services.


In collaboration with the Institute of Compound Semiconductors (ICS) at Cardiff University, CSC provides:

  • Fabrication and prototyping of novel CS device technology; and
  • Access to device characterisation facilities and expertise.

In  collaboration with IQE plc, CSC provides:

  • A direct and efficient route to scale-up to volume manufacturing services; and
  • Commercialisation services such as market assessment, manufacturability advice and volume CS materials process development.
