MOSCOW (MRC) -- Shin-Etsu Chemical Co., Ltd. has developed new process technologies that can be applied for the manufacturing of Micro LED displays, said Polymerupdate.
The size of a Micro LED chip is not visible to the naked eye, with the length of one side being less than 50 ?m (micrometers). For example, in order to manufacture one 4K display that has 4 times the resolution of a conventional high-definition screen, it is necessary to precisely array about 24.90 million chips. In order to implement improvements in the complexity and yield ratio in the processes of Micro LED chip manufacturing and the transfer process of each chip, Shin-Etsu Chemical has been working together with Shin-Etsu Group companies to take advantage of our unique materials technologies. We have proceeded to develop various advanced innovative transfer equipment and transfer parts to solve the key manufacturing challenges of Micro LED display manufacturing.
The new process technologies we are announcing were jointly developed with Dexerials Corporation (Head Office: Shimotsuke City, Tochigi Prefecture, Japan; President: Yoshihisa Shinya) and introduces innovative technology that will transfer singulated anisotropic conductive film (ACF) of?80?m or less onto the targeted location by laser equipment. Employing this technology, it becomes possible to transfer the singulated ACF only to the designated plate and mount the Micro LED chip on it and makes the repair process in Micro LED display manufacturing easy to carry out, a matter which had been a large issue up until now.
We remind, on 16 Feb 2022, Shin-Etsu Chemical Co Ltd announced plans to invest over $695 M to expand its silicone manufacturing plants across Japan to meet a very strong demand for advanced functional products. According to the company, the new plant investments will expand the manufacturing capacity of "highly diversified" kinds of silicone resins, fluids, and rubber end products by 2025. The expansion project will start with Shin-Etsu's main facility, the Gunma Complex in Gunma Prefecture, and will be followed by two other facilities in Naoetsu, Niigata Prefecture, and Takefu, Fukui Prefecture.
