Shin-Etsu Chemical has developed new process technologies that can be applied for the manufacturing of Micro LED displays.

The size of a Micro LED chip is not visible to the naked eye, with the length of one side being less than 50 μm (micrometers).

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 were jointly developed with Dexerials Corporation and introduces innovative technology that will transfer singulated anisotropic conductive film (ACF) ofΦ80μm 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.
