Manufacturers' technical optimization and new actions of cost reduction and production increase

With the increasing demand for sterilization products in our daily life, there are new requirements for various indicators, efficiency, production cost and production capacity of deep UV LED products. Based on the market demand, relevant manufacturers of deep UV LED epitaxial growth announced the latest developments:

 

CCS 3x2 MOCVD system

 

The CCS 3x2 MOCVD system has a capacity of 3x2 inch wafers, and the maximum operating temperature is 1400 ° C. aixtron Ltd, a subsidiary of aixtron se, a German deposition equipment manufacturer, provided it to Boise State University from its close coupled nozzle metal organic chemical vapor deposition (CCS MOCVD) product series for compound semiconductor materials.

 

The CCS 3x2 system includes a new structure capable of depositing graphene and hexagonal boron nitride (hBN) on sapphire as gallium nitride (GAN) - based ultraviolet light emitting diodes (UV LEDs). In addition, aixtron's proprietary Argus and epison in situ measurement technology is the only system technology that can be configured for combining 2D and Gan research, and also allows the growth of heterostructures.

 

 

Promaxy for 4 reaction chambers ® UV models

 

In view of the material crystal quality, surface morphology characteristics and crack control of AlN (aluminum nitrogen) grown by deep UV LED epitaxy, which has a significant impact on improving the power conversion efficiency and yield, on this basis, Zhongsheng optoelectronics has made further improvements in technology and established the core technology of MOCVD for epitaxial production of high-quality AlN substrates, which can increase the production capacity of 2-inch chips to 15 chips.

 

Risheng optoelectronics subsequently launched the promaxy with four reaction chambers ® UV models further achieve cost reduction and production increase. It can not only produce the full structure of deep UV LED by independent epitaxy per cavity, but also produce AlN substrate and led structure by cavity integrated epitaxy. Its surface feature rq<0.5nm, edge crack control <2mm high-quality, low-cost AlN substrate, has become the first choice for many customers of deep UV LED.

 

 

Qingdao fluorescent Innovation Technology Co., Ltd. has a professional post doctoral team, focusing on the research of UV sterilization application. After years of deep cultivation in the UV industry, the company has obtained a number of national invention and utility model patents. At present, a number of sterilization module products have been put into the market.
