Guanggong team teamed up with Maiwei Technology to achieve important breakthroughs in Mini/MicroLED technology

Not long ago, there was a breakthrough in the State Key Laboratory of Precision Electronic Manufacturing Technology and Equipment jointly established by Guangdong University of Technology and the Ministry of Education. The team of Professors Chen Xin/Chen Yun, together with leading enterprises in the industry such as Suzhou Maiwei Technology Co., Ltd., has made major breakthroughs in the research and development of key core technologies and equipment in the field of Mini/MicroLED display. The relevant results have been industrialized and applied, helping the high-quality development of my country's new display industry.

As a new generation of display technology, Mini/Micro LED has the advantages of high brightness, high contrast, and low power consumption. It is in line with the "dual carbon" strategic orientation and has huge market potential in consumer electronics, high-end display and other fields. However, high-efficiency and high-yield chip mass transfer and bonding technology have long been the focus of international technology competition.

With the special support of the national key R&D program "Intelligent Robots", the Guangdong University of Technology team invented a new principle of two-dimensional high-frequency collaborative flying spines. Through the technical combination of "flying spines to increase speed, macro-micro composite to ensure accuracy, and directional compensation to increase yield rate", a full-chain independent technology system covering transfer methods, bonding processes, core components, and system control was built. In response to the problem of transferring smaller-sized Micro LEDs, the team has further made breakthroughs in key technologies such as high-speed precision alignment, laser process coordination, and error compensation, and has obtained more than 20 Chinese and American invention patent authorizations.

Through in-depth industry-university-research cooperation with Suzhou Maiwei Co., Ltd., a leading pan-semiconductor equipment company, scientific research results are quickly transformed into real productivity. The flying spiny crystal mass transfer robot jointly developed by both parties has achieved a leap-forward improvement in performance indicators and significantly reduced raw material consumption and manufacturing costs.

This equipment not only reaches the international leading level in terms of technical indicators, but also enables batch shipments of Mini LED mass transfer production lines, equipping my country's display industry with "Chinese core". At present, relevant equipment has been applied on a large scale in commercial and consumer scenarios such as large-screen displays, all-in-one conference machines, and home theaters, promoting the upgrading of my country's high-definition display industry.

While making breakthroughs in Mini LED technology, a joint research team formed by Guangdong University of Technology and Suzhou Maiwei Technology (Zhuhai) Co., Ltd., a subsidiary of Suzhou Maiwei Co., Ltd., is targeting the frontier areas of Micro LED and realizing the localization of equipment such as laser stripping, giant rotation, bonding, and repair. The G3.5 generation line laser bonding equipment has been delivered to customers. The team created the first overall solution for silicon-based Micro LED hybrid bonding wafer reconstruction, covering key equipment for the entire process such as wafer grinding and polishing, femtosecond laser cutting, plasma processing, hybrid bonding, etc. It integrates semiconductor integration technology with new display innovation, opening up a new path for large-scale mass production of ultra-high-definition displays.
