Changelight orders more Veeco AsP MOCVD systems
Veeco Instruments has announced that Chinese LED company Changelight has ordered additional TurboDisc K475i AsP MOCVD systems to increase production of red, orange, yellow LEDs. Changelight qualified and put into production its first K475i system in February 2016.
"Our first K475i system has exceeded our expectations in terms of lowering manufacturing costs, driving exceptional uniformity and producing unmatched yield and brightness," said Shuangxiang Zhang, general manager of Yangzhou Changelight. "Adding this capability will enable us to meet existing demand for red, orange and yellow LEDs, as well as position ourselves to capitalise on the emerging AsP photonics market."
Introduced in February 2016, the K475i system incorporates proprietary TurboDisc and Uniform FlowFlange MOCVD technologies and enables Veeco customers to reduce LED cost per wafer by up to 20 percent compared to alternative systems through higher productivity, best-in-class yields and reduced operating expenses.
"Changelight's quick adoption of Veeco's K475i technology is a testament of its production-proven functionality," said William J. Miller, president, Veeco. "Changelight will benefit from superior uniformity and repeatability lowering their cost of ownership."
Veeco's proprietary Uniform FlowFlange technology (pictured above) is said to produce films with very high uniformity and improved within-wafer and wafer-to-wafer repeatability resulting in low cost of ownership. The technology is designed to provide fast process optimisation and fast tool recovery time after maintenance, according to the company, enabling high productivity for applications such as lighting, display, solar, edge-emitter laser diodes, VCSELs and heterojunction bipolar transistors.
