RPCVD technology offers low-cost growth alternative for GaN-based LEDs

Nov. 5, 2008
By eliminating ammonia and using large, low-cost substrates, a new growth technology could offer a challenging alternative to conventional MOCVD processes, writes Giles Bourne.
Since the opening in July of BluGlass Ltd’s pilot manufacturing plant for GaNbased LEDs, a revolutionary growth technology is now accessible to the LED industry. The installation of the Australian company’s first commercial-scale mass production deposition tool at its new headquarters (see Links) means that BluGlass will be able to further test its remote plasma chemical vapor deposition (RPCVD) process under the conditions required to demonstrate the technology’s full potential. BluGlass is currently in discussions with a number of major LED manufacturing groups with a view to demonstrating its unique process.

This is the culmination of 15 years’ research at Sydney’s Macquarie University by a team led by the technology co-founder, Scott Butcher. Commercialization work during the last two years has been undertaken by BluGlass, which trades as a company on the Australian stock exchange, under an arrangement whereby it also owns all of the relevant patents.
