Micledi Microdisplays BV (Leuven, Belgium) , a developer of microLED arrays, has struck a manufacturing collaboration with GlobalFoundries.

Under the agreement Micledi’s display technology for augmented reality glasses will be combined with Globalfoundries’ 22FDX manufacturing process. This is a fully-depleted silicon-on-insulator (FDSOI) process that will help Micledi achieve the brightness, resolution, power, size, and economies of scale needed for its technology to become affordable for consumers.

Companion ICs, which can be customized for different customer applications, will provide the image processing, driver and control functions needed to complete the display modules using wafer-to-wafer hybrid bonding.

“We are pleased to collaborate with GF as we move from pilot-line manufacturing to mass production in a world-class fab,” said Sean Lord, CEO at Micledi Microdisplays, in a statement. “To enable optimum microdisplays for AR, Micledi has developed a unique and innovative solution for microLED manufacturing integrating both the controller IC and emitter module to leverage GF’s 300mm semiconductor manufacturing technology, capitalizing on manufacturing precision for product performance, high volume and low-cost.”

Micledi Microdisplays was spun-out from the IMEC research institute in 2019. Micledi’s technology is based on III/V materials processing, 3D integration and silicon-based processing combined with a proprietary ASIC to provide a self-contained, compact monolithic AR display.
