Strategic Collaboration to Boost Micro LED Production
Japan’s Advantest Corporation, a leader in semiconductor testing equipment, has announced a technological partnership with Toray Engineering Co., Ltd., aimed at advancing the efficient production of Micro LED displays. The collaboration, revealed on April 10, seeks to leverage each company’s expertise in inspection, transfer, mounting, data analysis, and manufacturing technologies to improve production efficiency in the Micro/Mini LED sector.
Integrating Expertise for Efficient Manufacturing
Advantest and Toray Engineering are combining their specialized knowledge to enhance the efficiency of Micro LED manufacturing. Advantest brings its strengths in manufacturing equipment, process coordination, data analysis, and testing technologies, while Toray Engineering contributes its expertise in visual inspection, laser transfer, mounting, and repair technologies. This partnership is expected to accelerate the development of the Micro LED display market by effectively identifying and addressing defects during LED production.
Advantest’s Role in Semiconductor Testing
Founded in 1954, Advantest is a globally recognized supplier of semiconductor automated test equipment. The company operates three main business segments: semiconductor and component test systems, mechatronic systems, and service and support operations. Advantest addresses a wide range of semiconductor testing needs across various industries, including consumer electronics, automotive, communications, and medical devices. The semiconductor and component test systems segment, which represents 70% of Advantest’s total sales, focuses on SoC (System on Chip) testers and memory testers, crucial for testing display driver ICs, logic semiconductors, analog semiconductors, RF devices, DRAM, and NAND memory.
Toray Engineering’s Expertise in LED Technologies
Toray Engineering, a subsidiary of Toray Industries, Inc., specializes in advanced engineering solutions and services. The company is known for its cutting-edge technologies in mounting and inspection, which it integrates into its Micro/Mini LED display manufacturing processes and equipment. Toray Engineering currently offers laser micro-repair equipment (LMT series) for adjusting defective Micro/Mini LED chips and wiring and has developed a Micro LED laser transfer technology for its RAP-LLO Micro LED production machine to improve the efficiency of transferring tiny LED chips.
Innovations from Toray Industries
Toray Industries, the parent company of Toray Engineering, is also actively involved in the research and development of Micro LED equipment and materials. The group has developed several innovative materials aimed at enhancing production efficiency and display quality, including “laser transfer release materials” for rapid LED chip arrangement, “bonding materials” for simplified LED and wiring processes, “substrate-side routing materials” for larger displays, and “optically defined nanocarbon conductive pastes.”
Impact on Global Sustainability and Next-Generation Displays
The collaboration between Advantest and Toray Engineering is set to drive the development of more efficient and higher-quality Micro LED display manufacturing technologies. This partnership contributes to global sustainability efforts by promoting the next generation of environmentally friendly display equipment.
