LG Innotek and Chinese start-up acquire LED growth systems

Feb. 9, 2009
Companies in Korea and China have bought new systems for the growth of GaN-based LED materials.
Korea-based LED maker LG Innotek has ordered an additional four TurboDisc(r) K465(tm) metal-organic chemical vapor deposition (MOCVD) systems from Veeco Instruments.

The machines will be used to grow gallium nitride (GaN) -based material for LEDs, primarily for TV backlighting applications. Veeco said that the orders were received in the fourth quarter of 2008.

Steve (Tchanghun) Oh, Vice President in charge of LED technology at LG Innotek, commented, “Veeco’s MOCVD tools enable a smooth transition to larger wafer sizes offering a longer capital life along with a proven advantage in productivity…We are very impressed with the level of support and collaboration from Veeco in helping us to improve our cost of ownership.”

Bill Miller, Senior Vice President, General Manager of Veeco's MOCVD Operations commented, “We are pleased to be helping LG Innotek meet their production demands for HBLEDs for television backlighting applications. The K465 has been designed to help customers seamlessly transition to larger wafer sizes, a critical benefit to our customers as they advance LED technology.”

Aixtron delivers system to Chinese start-up

In related news, Yangzhou Zhongke Semiconductor Lighting Center Co. Ltd. has acquired an MOCVD system for GaN LED growth from Aixtron AG.

The Close Coupled Showerhead® CRIUS® system with 31x2-inch wafer configuration was delivered to Yangzhou Zhongke’s state of the art facility in the Yangzhou High-Tech Venture Services Center, PR China in the fourth quarter 2008. Its application will be for the development and volume production of UHB blue/green LEDs.

Yangzhou Zhongke is a start-up company, building on the R&D achievements of the Institute of Semiconductors of Chinese Academy of Sciences (ISCAS).

Guohong Wang, CEO of Yangzhou Zhongke, said: “Our goal is to promote the LED-based solid-state lighting industry in China. I have long-time familiarity with Aixtron MOCVD AlInGaP systems used for diode laser applications at ISCAS. The CRIUS® has set the standard for UHB GaN LED production and we keenly anticipate its rapid commissioning.”

Yiping Zhen, CTO of Yanghzhou Zhongke, said “Our plan is ambitious, we want to develop as rapidly as possible a top class solid-state lighting technology. I believe we can achieve this with equipment and service of the high quality we can rely on Aixtron to deliver.”
