An Australian company, BluGlass, has said that it has entered a collaboration agreement with an unnamed MicroLED company which is described as “well-funded”. The companies will check if the the firm’s Remote Plasma Chemical Vapor Deposition (RPCVD) production technology can be used to make RGB MicroLEDs.

The company also said that it is working with Lumileds and has extended a collaboration agreement for making LEDs with RPCVD.
In MOCVD, the higher temperature growth of the p-GaN top layer compared to the multi-quantum well (MQW) layer, or the active region of an LED can cause some of indium (In) to diffuse out of the active MQW layer and reduce the LEDs light output. MOCVD cannot effectively grow high performance p-GaN at lower temperatures. RPCVD has great potential to improve device performance by growing a low temperature p-GaN layer which in turn improves the stability of the InGaN layer during growth. Source BluGlass
