TurboDisc MaxBright® MHP™ GaN MOCVD Multi-Reactor System
Veeco

MOCVDs are crucial to LED chip production. The quality, efficiency, and yield of epitaxial wafers may affect the cost and output of the LED epitaxial wafer plant. Veeco’s MaxBright MHP, the new GaN MOCVD Multi-Reactor System, is considered a highly efficient device.

Compared with the original MaxBright, the MaxBright MHP showed a 20% improvement of the LED chip wavelength uniformity. Thermal management and process compatibility are also improved so that each reaction process will improve the uniformity. The company has greatly enhanced the yield of 2-inch and 4-inch wafers by using the FlowFlange technology, thus they received the MOCVD with the Best Yield award.

MOCVD with the Highest Efficiency

AIXTRON SE

AIX G5+: A novel 5 x 200 mm GaN/Si MOCVD reactor technology package

As for mass produced products, AIXTRON’s new G5+ has an output that is significantly greater than that of G5; it is able to produce five 8-inch epitaxial wafers at a time, and as one of the equipments with high efficiency, it is the MOCVD reaction system that can produce the largest amount of 8-inch LED chips. This product also applies the rotation system in order to maintain uniformed LED chip production, and it is precisely managed by a management system. 8-inch LED chips require a fine management system in order to avoid yield loss. Larger chips may require an even more careful management during the production process.

The epitaxy process requires a new management method to control the gas flow and deposition. This device also supports LED epitaxial silicon substrates. According to current investigations, the 4-inch and 6-inch products produced by the company’s system showed an increased efficiency and yield. The G5+ has therefore received the MOCVD with the Highest Efficiency award.

Best Handheld LED Testing Equipment

LED measuring instruments

The LED Meter_MK350 stood out among other competitors due to its color, luminance, peak wavelength, and spectrum. The weight of this product is light, and the production cost is low; it is easy to operate, and the overall quality is good. Therefore, the LED Meter_MK350 won the Best Handheld LED Testing Equipment award.

Best BEOL LED Testing Equipment

LED lighting testing system –model: 58158-SC

The Chroma 58158-SC is an online testing equipment for LED lighting products; it provides testing for the luminous flux, CCT, CRI, luminous efficacy (lm/w), flicker, and light distribution of LED lighting products. Manufacturers can test all of the above features within one testing; this testing equipment not only saves the time and cost of manufacturers, but also automatically integrates with the production line. Therefore, the Chroma 58158-SC won the Best BEOL LED Testing Equipment award.
