eLux installs a new automated fluidic assembly R&D tool, unveils a new microLED display prototype

USA-based eLux was established in 2016 as a spin-off from Sharp Labs of America, to commercialize a unique MicroLED production technology. A year ago we discussed the company's technology and business with its CEO, Jong-Jan Lee.

eLux automated fulidic assembly tool, 2021

Today eLux announced that it has installed an automated fluidic assembly tool at its prototype fab in Taiwan. The new tool features fully automatic cassette-to-cassette fluidic assembly of ten display panels, each up to 15-inch in size. The tool has provisions for capture and recycle of microLEDs and assembly fluids to minimize operating costs, and its capacity can be expanded by adding two additional modules.

A Tier-1 US LED producer selects Aixtron's equipment for microLED production

Aixtron announced that a US Tier-1 LED producer has selected Aixtron's AIX G5+ C equipment. Aixtron did not provide any more detials on this specific deal, but it does say that its new customer is "one of the world's technology leaders in the field of advanced LED technology".

Aixtron says that this AIX G5+ C system uses wafer-level control (based on Auto-Feed Forward) of the film surface temperature during the epitaxial process in combination with Ultraviolet (UV) pyrometry. This warrants, according to Aixtron, a very accurate control of the Indium incorporation into the Multi-Quantum wells (MQW), which will ultimately define the wavelength consistency among all produced wafers.

STRATACACHE CEO details the challenges and goals of the company's upcoming US-based microLED display production fab

Global digital signage solution provider STRATACACHE is constructing the first US-based complete display production facility in Eugene, Oregon. The future MicroLED E4 fab is planned to commence production in 2022, and the fab will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly.

This project is extremely interesting, and we set out to discuss it with STRATACACHE's founder and CEO, Chris Riegel. At STRATACACHE, Chris leads strategic direction, technology development and engineering operations, and the MicroLED fab project seems to be personally spearheaded by him.

XDC installs the world's first 300mm elastomer stamp based microLED transfer tool

MicroLED display technology developer X Display Company (XDC) announced that it installed the world's first 300 mm elastomer stamp based mass MicroLED transfer equipment late in 2020. This tool was installed in the US and the company hopes to start shipping several similar tools for its customers later in 2021.

XDC spun out of X-celeprint in 2019 and retained the equipment organization from that transaction. XDC has over 15 years of experience with mass transfer micro printing technologies, and is offering a range of tools for microLED transfer, suitable for R&D work and industrial-scale production.

Coherent reports significant increase in MicroLED display system bookings, supplies laser systems to almost the entire industry

Laser equipment maker Coherent says that it saw a "significant increase" in the level of investment and bookings related to MicroLED displays. These tools are going to be used for process development, as a precursor to mass production.

Coherent reveals that its MicroLED customer base includes almost all current OLED and LCD manufacturers and many well-known MicroLED specific startups and display industry integrators. Coherent is offering multiple UV solutions for four separate MicroLED processes - CLA for high performance low power consumption back planes, laser lift-off for customers using sapphire carrier, laser transfer and laser repair.

Aledia orders Veeco's 300mm MOCVD systems for its upcoming MicroLED production fab

Veeco announced that France-based 3D GaN LED developer Aledia has selected the company's Propel 300mm HVM MOCVD system for its microLED production plant. Veeco says that the Propel system, featuring a SEMI-compliant Equipment Front End Module (EFEM) with cassette-to-cassette automation, was chosen due to its highest productivity with the lowest defectivity compared to alternatives.

Last month Aledia announced that it plans to establish a 140 million euros LED production fab in Champagnier, near Grenoble in France. The company already raised 80 million Euros and its great to see the company already ordering production equipment.

CyberOptics reports strong traction in 3D microLED metrology equipment

High-precision 3D sensing developer CyberOptics Corporation announced its financial results for Q2 2020, with $16 million in sales and a net profit of $1.6 million. The company says it is enjoying a "first-mover status" in the microLED inspection and metrology market.

CyberOptics says that at the end of the quarter it received a $2.5 million order for SQ3000 Multi-Function systems for micro LED applications, and additional micro LED-related orders are anticipated during the second half of 2020.

ALLOS and Veeco up-scale GaN-on-Si microLED production technology to 300 mm wafers

German-based GaN-on-Si developer ALLOS has applied its technology to large 300 mm epiwafers. ALLOS says that scaling up to 300 mm wafers enables higher production efficiencies and thus lower costs. ALLOS estimates that the higher area utilization alone accounts for a cost advantage of 40% compared to standard LED wafers. Standard 300 mm silicon line tools also offer higher production uniformity and yield.

ALLOS demonstrated the 300 mm scale-up using a reactor made by Veeco who announced selling the first 300 mm GaN reactor to a leading-edge semiconductor fab just some month ago and also showed 300 mm wafer data at CES. ALLOS reports a wavelength uniformity of consistently below 1 nm and "all other production requirements like bow of < 40 µm and SEMI-standard thickness of 725 µm". ALLOS says scaling to 300 mm shows how robust its GaN-On-Si technology is.
