Successful customer prototype of RPCVD p-GAN in high performance microLED applications

Australian semiconductor technology developer, BluGlass limited (ASX:BLG) together with its foundry customer, micro-transfer printing company, X-Celeprint have implemented BluGlass’ unique Remote Plasma Chemical Vapour Deposition (RPCVD) p-GaN technology in high performance microLED display prototypes (pictured).

BluGlass’ foundry customer, X-Celeprint, is using RPCVD deposition for its unique technology demonstrations. X-Celeprint’s active matrix microLED displays that use RPCVD p-GaN have demonstrated good luminance with colour uniformity, quantum efficiency and forward voltage that equals current high-performance commercial applications of 2000cd/m2.

X-Celeprint is a world developer of micro-transfer printing (?TP) technology. ?TP is a cost-effective and scalable manufacturing platform for integrating microscale devices such as lasers, LEDs or integrated circuits onto non-native substrates.  They provide custom design services for micro-transfer printing stamps and printers for a range of customers. 

BluGlass is commercialising a breakthrough semiconductor technology called Remote Plasma Chemical Vapour Deposition (RPCVD) in the global LED, microLED and power electronics industries. BluGlass’ patented hardware and processes offers manufacturers unique performance advantages due to RPCVD’s low temperature and low hydrogen growth conditions.

X-Celeprint has been a long-standing customer of BluGlass’ foundry services and were the first adopter of RPCVD for microLED demonstrations.

X-Celeprint’s Vice President of Displays, Matt Meitl said “X-Celeprint works with BluGlass to demonstrate our micro-transfer printing capability for microLED displays.  BluGlass’ creativity in epi-wafer design, unique capabilities in epitaxial growth, and dedication to continued product improvement make them a valuable development partner. We continue to use these advantages in our micro-LED development.”

BluGlass Chief Technology Officer, Dr. Ian Mann said “It’s rewarding after many years of developing RPCVD
p-GaN to see our technology being trialed in customer devices, particularly for the emerging microLED display market. This microLED prototype demonstrates good performance and X-Celeprint are seeing the advantage of using RPCVD in their innovative products”.

X-Celeprint continues to use BluGlass’ RPCVD foundry services (early stage, fee-for-service revenue) to advance the technical demonstrations of their active matrix microLED displays. X-Celeprint continue to actively market their unique, cost effective, high performance display technology in the emerging microLED market.
