The technology being developed and commercialised by BluGlass is a process for manufacturing semiconductor materials for high efficiency devices such as LEDs, power electronics and concentrated solar cells for utility scale solar.

This process, uses remote plasma chemical vapour deposition (RPCVD) and the potential to offer many advantages over current manufacturing techniques.

Evolved from more than 15 years of low temperature thin film growth research at Sydney’s Macquarie University, the RPCVD process has been specifically developed for the low temperature growth of nitride based thin films, such as gallium nitride (GaN) and indium gallium nitride (InGaN).

Currently a process called MOCVD is the most widely used in the production of high brightness LEDs. This process requires much higher growth temperatures of typically up to 1200°C.

With a lower growth temperature than MOCVD, RPCVD has the potential to allow electronics manufacturers to create higher performing devices at lower cost while also being friendlier to the environment.

The BluGlass IP portfolio now comprises 41 patents accepted or granted in key semiconductor area’s including Japan, China, Europe and the USA.

The RPCVD process is potentially suited to a range of applications including:

  • Light emitting diodes (LEDs) and other optoelectronic devices

  • Power electronics

  • Nitride based solar cells for CPV applications

  • Photo and laser diodes
