Huacan will cooperate with Australian companies to develop aluminum nitride applications on LEDs

Australian company BluGlass Ltd. announced that it will work with China's leading LED chip maker Huacan Optoelectronics to explore the application of aluminum nitride (AlN) low-temperature deposition on high-brightness LEDs and explore the advantages of RPCVD in green LED production. Through the cooperation agreement, Huacan Optoelectronics will supply BluGlass with 4-inch wafer products and manufacture LED devices for testing.

Through this agreement, BluGlass intends to demonstrate its cost and performance advantages of low temperature remote plasma chemical vapor deposition (RPCVD) for Huacan Photovoltaic Systems for low temperature deposition of p-GaN layers of green LEDs. The company also plans to explore the use of aluminum nitride (AlN) low-temperature deposition on sapphire substrates for the manufacture of high-brightness LEDs.

BluGlass developed a method for the use of long-range plasma low-pressure chemical vapor deposition (RPCVD) gallium nitride (GaN) and gallium nitride indium on glass substrates after independence from the Group III nitride division at Macquarie University in Sydney, Australia. Low temperature process of materials such as InGaN). The light-emitting diodes (LEDs) and solar cells produced by this process have the advantages of cost saving, large throughput and high efficiency. BluGlass owns the patent for this technology in major semiconductor markets such as the US, China, Europe and Japan.

Huacan Optoelectronics Co., Ltd. is a famous LED chip manufacturer in China. The company is committed to research, development, production and sales of high-quality LED epitaxial materials and chips based on GaN-based blue and green light products. It has international leading technology research and development capabilities and maturity. Production process.

It is reported that the two companies are expected to develop the ability to perform several iterations to demonstrate their performance. Huacan will use BluGlass' new RPCVD chamber design to improve the uniformity of PRCVD deposition for LED fabrication. Huacan expects to commission BluGlass to build RPCVD equipment in the next few months. The two companies will work together to improve the process and enable the BluGlass system to manufacture high-efficiency, high-brightness green and white LEDs at low cost.
