Soitec’s Relaxed InGaN Substrates Enable Pure Red Emission for Full-Color Micro LED Displays

Micro LED displays require the use of red, green and blue (RGB) LEDs, achieved by mixing nitride LEDs and phosphide LEDs. This mixing causes blue, green and red LEDs to behave differently in terms of temperature and aging, which impacts the quality of image color. Moreover, blue, green and red LEDs each require specific electronic drivers, making integration more complex. (Figure 1: Red emission at 630nm of 100µmx100µm of full InGaN LED grown on Soitec’s InGaNOS) RGB LEDs composed of the same material inducing the same behav...

Disruptive Substrate Technology for Direct Green and Red Micro LEDs

The ideal solution for microLED makers would be the availability of efficient nitride LEDs in both green and red. In this case, all RGB LEDs would be composed of the same material with the same behaviors and driving conditions. The challenge is to find one material capable of spanning the blue to red spectrum.

Veeco MOCVD Chosen for CEA-leti adn Aledia's New Nano-LED Venture

 Veeco Instruments Inc. (Nasdaq: VECO) announced today that CEA-Leti, a world-renowned research lab based in Grenoble, France, has selected Veeco’s TurboDisc® K465i Metal Organic Chemical Vapor Deposition (MOCVD) system for its program with Aledia, its nanowire-LED partner.  Aledia is a start-up company spun out of the CEA-Leti labs in 2011, and based at the CEA site. It counts among its three founders two former CEA researchers, Xavier Hugon and Philippe Gilet. Aledia’s goal is to manufacture 3D nanowire-based LEDs for solid-state lighting applications on thin silicon wafer substrates, of 8 inches or greater in diameter, at a cost significantly ......
