Changelight chooses Veeco MOCVD for GaN LEDs

Purchase marks Changelight's move into GaN-based lighting market 

Veeco Instruments has announced that Xiamen Changelight has chosen it as the primary equipment provider for making GaN based blue/green high brightness LEDs for display and general lighting applications.

During the second quarter of 2014, Changelight ordered multiple TurboDisc MaxBright M GaN MOCVD Systems. In addition, Changelight purchased a TurboDisc K475 MOCVD system to expand its production of red, orange and yellow LEDs.

"In the past we have used competitive MOCVD equipment for the majority of our production of  red, orange and yellow LEDs," said Wang Xiangwu, general manager of Changelight. "As we make this important move into the GaN-based lighting market, we decided to switch to Veeco's MaxBright M MOCVD system, which we believe will offer the best throughput and cost of ownership to help enable our success and growth in the general illumination market."

The MaxBright M offers a modular, compact design with a number of layout configuration options to fit various fab spacing requirements, including sub-floor storage, enabling more wafer starts per square foot, which translates into a lower cost of ownership.

"We have seen Changelight dominate the  red, orange and yellow market in China for some time and believe that, with our technology and its knowledge of the industry, Changelight is well positioned to successfully expand into the backlighting and general illumination market," said Jim Jenson, senior vice president and general manager of Veeco MOCVD.

Xiamen Changelight was established in February 2006. It  specialises in quaternary alloy AlGaInP of red, orange, yellow LED wafers, chips and high-performance GaAs solar cells.
