CSC and Kubos to commercialise cubic GaN

News

Technology has the potential to circumvent key limitations in conventional GaN based LED devices

The UK Compound Semiconductor Centre (CSC) in Cardiff and Kubos Semiconductors Ltd in Cambridge have signed a Memorandum of Understanding to pursue the commercialisation of cubic GaN epitaxial technology for high efficiency, LED lighting applications.

The agreement will accelerate the development of Kubos IP on MOCVD reactors at CSC’s St Mellons facility, via the collaboration of CSC, Kubos, IQE and Cambridge University staff.

The advantage of Kubos’ proprietary cubic GaN growth technology is that it has the potential to circumvent some of the key limitations in conventional GaN based LED devices. In particular, the removal of internal electric fields and narrower bandgap mean that cubic GaN will deliver more efficient green and amber LEDs overcoming the “green gap” problem. This will allow improved displays and also light-bulbs that can be varied to mimic the natural changes in daylight through the day.

The CSC facility in St Mellons is co-located with significant volume manufacturing capacity of its joint venture owners IQE, hence the infrastructure provides the advantage of seamless scale up from low volume R+D and prototyping activities, through to process transfer onto state of the art Aixtron MOCVD production tools, installed during a £10M capital investment completed at the site in 2017.

Wyn Meredith, CSC Director, commented: ‘This is a great example of our ability to accelerate new epitaxial technologies to market by supporting an ecosystem where academic researchers work in an industrially relevant environment. It provides a very low-cost model for spinouts and new ventures to leverage the significant capital investment required to commercialise new epitaxial technologies. The cost and risk of commercialisation is reduced with the added benefit of working with a wide range of relevant capability and partners in the emerging CSconnected Compound Semiconductor Cluster in South Wales’.

Caroline O’Brien, CEO of Kubos said: “CSC is an ideal partner for Kubos as it supports our fabless business model and assists with the tight control of R&D costs. As our technology matures it will also mean that we have an established relationship with a partner who can support the move to high yield, high volume processes that is required for a commercially viable LED technology.”

Secure Your Hydrogen Supply

A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.

Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.

Take control with Nel on-site hydrogen generation.
