ams OSRAM and AIXTRON announce qualification of AIXTRON G5+ C and G10-AsP systems on 200mm wafers for Micro LED application

The MOCVD systems AIX G5+ C and the new G10-AsP from AIXTRON SE offer AIXTRON planetary technology which is paving the pathway for the next generation of high-resolution Micro LED displays. In spring 2022, ams OSRAM had announced plans to create additional manufacturing capacity in 200mm allowing production of LED and Micro LED at its existing location in Malaysia. The MOCVD systems are expected to help enable volume production of Micro LED for a new generation of display applications.


“AIXTRON and ams OSRAM have a long-standing cooperation, and we are familiar with the performance and quality standards of the equipment. For an ambitious project like the development and production of Micro LED for AsP and GaN devices, we needed exactly such a partner at our side”, says Robert Feurle, Executive Vice President and Head of Business Unit Opto Semiconductors at ams OSRAM. 


Dr. Felix Grawert, CEO and President of AIXTRON SE, adds: “The G10-AsP and AIX G5+ C qualification at ams OSRAM is a very important milestone in our company’s history. ams OSRAM is a world-class LED manufacturer and perfectly positioned to enable the fundamental new technology that will come to market. We are on the verge of a technology shift away from conventional display technologies to a new type of Micro LED displays. Now, AIXTRON is entering one of the future’s growths markets that has an enormous potential, and we are doing this with a perfect partner at our side.” 


Micro LED technology offers very significant advantages for display technology such as higher pixel density, longer lifetime, higher brightness, faster switching speed and a wider color spectrum. An important benefit is also the low relative energy consumption, which makes Micro LED technology ideal for upcoming generations of smaller display-equipped consumer devices which provide a very limited space for batteries.


The production of Micro LEDs comes with special requirements: volume production includes a special transfer process where multiple thousands of LED chips (arrays) with dimensions measured in micrometers are picked up and transferred. Any defect can result in dead pixels that can make an entire array useless. Hence, an almost error-free epitaxy process is necessary, minimizing defects and allowing for high yield and economically viable production of Micro LEDs.


AIXTRON’s new G10-AsP epitaxy tool has been designed to address the specific needs of this application: It is the world's first fully automated AsP reactor offering fully automated cassette-to-cassette wafer loading as well as a cleaning mechanism based on in-situ etching. Together, these two features have a major impact on the yield performance. In addition, the AIXTRON system offers the advantages of batch reactor technology: it comes with the lowest production cost per wafer currently available in the market and the highest throughput per cleanroom area. At the same time, the new tool comes with precise flow and temperature control permitting the best material uniformities run after run.
