Mojo Vision develops first 300mm GaN-on-Si blue LED wafer for micro-LED display

Mojo Vision Inc of Saratoga, CA, USA — which is developing and commercializing micro-LED display technology for consumer, enterprise and government applications — has announced a development and process milestone with the light-up of what it claims is the first 300mm GaN-on-silicon blue micro-LED array wafer, marking progress towards maturing micro-LED manufacturing at 300mm CMOS fabs.

This is Mojo Vision’s fourth record in the past five years for the display industry, after setting records for the smallest, densest dynamic display including 14k pixels per inch (PPI), 20k PPI and 28k PPI.

Micro-LEDs provide critical performance, efficiency and form-factor advantages essential to applications in extended reality (XR), wearables, automotive, consumer electronics, and high-speed communications. Mojo Vision says that it overcame extensive supply chain and wafer qualification issues, such as wafer bow and contamination concerns, to get GaN-on-silicon wafers allowed into the 300mm facility.

“At Mojo Vision we are focused on disrupting the existing display ecosystem, paving the way for scalability of the technology, and driving broader adoption in consumer and enterprise markets,” says CEO Dr Nikhil Balram. “Achieving cost-effective, large-scale manufacturing is the gap we are working to bridge with this breakthrough,” he adds.

“Mojo Vision’s advancements establish a roadmap for commercial scaling of micro-LED technology using processes compatible with industry-standard 300mm fabs,” comments Dr Rajeeva Lahri, advisory board member, who has over 40 years of experience in operations, R&D and business management in the semiconductor industry, including senior leadership roles at Globalfoundries, Freescale Semiconductor, National Semiconductor and Intersil.

Mojo Vision has received over $22.4m in new Series A funding at initial close, accelerating the development and commercialization of what it claims is the world’s smallest, densest micro-LED display technology for consumer, enterprise and government applications.
