Arima Chooses Veeco for GaN and As/P LED Production
The Taiwanese firm has purchased multiple TurboDisc K465i GaN and E475 As/P Metal Organic Chemical Vapor Deposition (MOCVD) systems to support the production ramp.
Veeco has announced that Arima Optoelectronics Corporation (AOC), has purchased multiple Metal Organic Chemical Vapor Deposition (MOCVD) systems during the recently completed second quarter.

“This innovation gives the lighting community a simple solution to a previously challenging issue - combining-lighting class LED efficacy with traditional incandescent color consistency,” said Paul Thieken, Cree, Director of Marketing, LED Components. “Providing our customers with Cree’s EasyWhite technology in smaller, single bins can lower their cost and potentially speed time-to- market, furthering the LED Lighting Revolution to obsolete energy-inefficient lighting.”
EasyWhite binning is a unique feature of Cree lighting-class multi-chip LED components that enables customers to specify a color temperature and lumen output, simplifying LED system design and improving LED-to-LED color consistency. Each bin, at the intersection of the black body locus and standard warm/neutral CCT points, is 94 % smaller than the respective ANSI C78.377 quadrangle and 75 percent smaller than current Cree EasyWhite bins.
XLamp MP-L and MC-E LEDs with EasyWhite 2-step bins are offered in 2700 K, 3000 K, 3500 K, and 4000 K and are now available in sample and production quantities with standard lead times.
Arima, a global provider of LED epitaxial wafers and chips has purchased the TurboDisc K465i Gallium Nitride (GaN) and E475 Arsenic Phosphide (As/P) MOCVD Systems.
Marco Kuo, President of Arima, said, “We have selected Veeco’s MOCVD systems because of our experience with their production-proven reliability and high productivity, which results in higher capital efficiency. Most of the systems will be installed in Shanxi Province, Northern China, where we have entered into an agreement with the local government to form a new joint venture company to manufacture LEDs for backlight applications.”
Bill Miller, Ph.D., Senior VP & General Manager of Veeco’s MOCVD Operations, commented, “We are pleased to expand our long-standing relationship with Arima, and to be chosen to support their production ramp.”
Claimed to have superior wavelength uniformity and excellent run-to-run repeatability, the production-proven K465i extends Veeco’s lead in capital efficiency - the number of good wafers per day for each capital dollar - for high volume LED manufacturers. The K465i provides ease-of- tuning for fast process optimization on wafer sizes up to 8 inches and fast tool recovery time after maintenance.
The TurboDisc E475 As/P MOCVD System is engineered for high-volume production of red, orange and yellow HB-LEDs, and offers a level of process control and reliability unmatched by competing MOCVD technologies.
