Aixtron Sells MOCVD System To Rainbow Opto For Blue LED Production

Aixtron AG announced it has sold a Thomas Swan 19x2 in. Closed Coupled Showerhead (CCS) gallium nitride epitaxy reactor to Rainbow Optoelectronics Material Shanghai Co. Ltd., China, for production of blue light-emitting diodes (LEDs).

The CCS system will complement Rainbows earlier purchases such as the AIX 2600G3HT in a 24x2 configuration, and will also be used for the production of high-brightness blue LEDs. It makes Rainbow one of the largest GaN LED capacity facilities in China.

We believe that this reactor technology has significant advantages over other vertical reactors in terms of excellent stability and uniformity. It will enable us to qualify and introduce very competitive state-of-the-art gallium nitride-based LEDs, Rainbow General Manager Hun-Huang Liu said in a press release.

CCS features the lowest deposition cost per wafer in the industry, according to the release, and provides exceptional uniformity of thickness, doping, and composition within epitaxial layers. The technology is used in the United States and Asia for the epi-growth of green, blue and UV LED structures.
