Kubos gains production support for cubic-GaN LEDs
Kubos was formed in formed in November 2017 using intellectual property from Anvil Semiconductors Ltd. (Coventry, England) and the University of Cambridge.
The agreement will allow Kudos to develop its IP on MOCVD reactors at CSC’s St. Mellons facility via the collaboration of CSC, Kubos, IQE and Cambridge University staff.
The use of cubic-GaN holds out the promise of a narrower bandgap and the removal of interal electric fields. The narrower bandgap allows for 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 JV 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 £10 million capital investment completed at the site in 2017.
“CSC is an ideal partner for Kubos as it supports our fabless business model and assists with the tight control of R&D costs,” said Caroline O’Brien, CEO of Kubos, in a statement. “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.”
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.”
