BluGlass Ltd of Sydney, Australia says it has succeeded in producing what it claims is the world’s first blue light emission from the uniform deposition of gallium nitride on a 6-inch diameter coated glass wafer.
The latest increase in scale offers the LED market the possibility of additional cost efficiencies, claims CEO David Jordan. Compared to current 2-inch industry-standard sapphire or silicon carbide substrates for commercial blue LED production, a 6-inch wafer has nine times the area.
The company is also developing a remote plasma CVD process for low-temperature deposition of GaN.
