R/O/Y LED maker Changelight adds MOCVD capacity with Veeco K475i technology

Epitaxial deposition and process equipment maker Veeco Instruments Inc of Plainview, NY, USA says that optoelectronics manufacturer Xiamen Changelight Co Ltd of Xiamen, Fujian Province, China has ordered additional TurboDisc K475i arsenic phosphide (As/P) metal-organic chemical vapor deposition (MOCVD) system capability to increase production of red, orange, yellow (R/O/Y) light-emitting diodes (LEDs). Changelight qualified and put into production Veeco's premiere K475i system in February.

"Our first K475i system has exceeded our expectations in terms of lowering manufacturing costs, driving exceptional uniformity and producing unmatched yield and brightness," comments Shuangxiang Zhang, general manager of Yangzhou Changelight Co Ltd. "Adding this capability will enable us to meet existing demand for red, orange and yellow LEDs, as well as position ourselves to capitalize on the emerging As/P photonics market."

Introduced in February, the K475i system incorporates proprietary TurboDisc and Uniform FlowFlange MOCVD technologies and enables users to reduce LED cost per wafer by up to 20% compared with alternative systems, it is reckoned, 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," says Veeco's president William J. Miller Ph.D. "Changelight will benefit from superior uniformity and repeatability, lowering their cost of ownership."

Veeco says that its proprietary Uniform FlowFlange technology produces films with very high uniformity and improved within-wafer and wafer-to-wafer repeatability, resulting in what is reckoned to be the industry's lowest cost of ownership. The patented technology is said to provide ease-of-tuning for fast process optimization and fast tool recovery time after maintenance, enabling the highest productivity for applications such as lighting, display, solar, edge-emitter laser diodes, vertical-cavity surface-emitting lasers (VCSELs) and heterojunction bipolar transistors (HBTs).
