iBeam Materials shows how to deposit both FETs and microLEDs directly on flexible metal foil substrates

iBeam Materials announced that it had successfully demonstrated the ability to produce high-performance GaN Field-Effect Transistors (FETs) directly on thin, flexible and rollable metal foil substrates.

This new technology complements iBeam's microLED deposition technology (demonstrated in the video above), and these FETs can be integrated with microLED chips in a side-by-side architecture. Both FETs and MicroLEDs are deposited on the flexible substrate without any transfer process.

CEA-Leti researchers developed a new CMOS-based process to produce high performance Micro-LED displays

Researchers at CEA-Leti developed a new process to produce high performance GaN Micro-LEDs displays, which the researchers say is simpler and more effective than current approaches.

The first step in the new process is transferring the micro-LED chips directly on top of a CMOS wafer. In the second step each complete "pixel", made from a CMOS driving circuit and micro-LED chips, is transferred to the display substrate.

X-Celeprint uses BluGlass' RPCVD p-GaN production process to develop a 2,000 nits Micro-LED display

In March 2018, Australia-based RPCVD developer BluGlass announced that it has entered into a collaboration agreement with a microLED company to investigate the use of its Remote Plasma Chemical Vapor Deposition (RPCVD) production technology to produce RGB MicroLED devices.

BluGlass now announced that its partner is X-Celeprint, that used the process to demonstrate a 2,000 cd/m2 micro-LED display that offers good luminance with color uniformity, quantum efficiency and forward voltage that equals current high-performance commercial applications. BluGlass reveals that X-Celeprint has been a long-standing customer of BluGlass’ foundry services and were the first adopter of its RPCVD system for Micro-LED production.
