Kubos raises £700k for red microLED technology

Kubos Semiconductors in Cambridge has won a £700,000 grant to develop its cubic GaN red microLED technology as its first patent is granted.

The grant is for a 24-month project to achieve 5% efficiency for red microLEDs by deploying the company’s proprietary cubic Gallium Nitride (GaN) process, called KubosLED. However the Future Economy Investor Partnerships (FEIP) grant from Innovate UK is subject to completing aligned investment led by the Development Bank of Wales following its first commercial customer order.

This should make the microLED technology viable in AR/VR headsets by doubling the efficiency achieved with other process technologies. Poor red microLED efficiency is currently one of the main factors constraining the AR/VR market and is the focus of other microLED startups such as Porotech, Allos and Mojo VIsion.

“We see huge demand for our technology every time we engage with potential customers and are delighted to have won our first major customer and secured further funding to ensure we reach our technology goals,” said Caroline O’Brien, CEO of Kubos. “These achievements underline the fact that KubosLED material technology is the leading contender to clear a major bottleneck that’s been holding back AR/VR adoption.”

The successful completion of the funding round will see Kubos open a development office in Wales to boost the existing collaboration with the Compound Semiconductor Centre (CSC, a partnership between Cardiff University, IQE and the Institute of Compound Semiconductors at Cardiff University, where the Kubos LEDs are processed and tested.

Kubos’s core cubic GaN process and product technology patent has now been granted in China, Japan, Singapore, and the US. Its patent portfolio has also been extended to include granted patents for silicon carbide epitaxy, which is used by Kubos as a growth substrate, for red MicroLED technology.
