Plessey partners with Axus Technology to deliver monolithic microLED displays

Plessey announces a partnership with Axus Technology (Axus), a global provider of CMP, wafer thinning and wafer polishing surface-processing solutions for semiconductor applications, to bring high-performance GaN-on-Silicon monolithic microLED technology to the mass market.

A number of Axus CMP and Scrubber systems have been deployed to enable critical wafer planarisation and preparation for wafer-scale bonding.

Wafer-level bonding poses significant technical challenges and even with the right equipment requires extensive know-how and refined processes. Shortly after installation of the systems in 2019, Plessey achieved the world’s first functional wafer-level bonded GaN-on-Si monolithic 1080p 0.7” diagonal 8-micron pixel-pitch microLED active-matrix display.
