Aixtron is upbeat on the microLED industry, says orders for its production tools have started to kick in

During Aixtron's Q1 2022 financial results conference call the company's CEO made some interesting comments on its microLED business and the market in general.

Aixtron says that it sees the microLED display industry advancing "as expected". Demand for its microLED production tools has "started to kick in". The company is "increasingly confident" that we will 'soon' see commercial microLED displays on the market.

Enkris launches GaN-on-Si microLED epiwafers on 300 mm wafers

China-based GaN epiwafer producer Enkris Semiconductor launched new microLED epiwafers. The "Full Color GaN" series offers GaN-on-Si microLED epiwafers, with wafers sizes of up to 300 mm.

Enkris' new epiwafers offers blue, red and green LED arrays, all based on the same material platform. Enkris Semiconductor uses its patented strain engineering and polarization engineering, which it says is unique, to expand its GaN-on-Si LED epiwafer product portfolio to all colors (with wavelengths of 390-650nm).

Porotech to supply JBD with red InGaN epiwafers for microLED displays

Porous-GaN material platform developer Porotech announced a partnership with Jade Bird Display (JBD). Under the agreement, Porotech provide JBD with its porous gallium nitride (GaN) technology.

Porotech says its native red InGaN LED epiwafer is not commercial. JBD now plans to use Porotech's porous GaN templates to manufacture InGaN-based red micro-LED displays for use in applications such as VR/AR headsets, AR smart sports goggles and head-up displays.

KAUST researchers develops highly-efficient GaN and InGaN red microLED devices

Researchers from King Abdullah's University of Science & Technology (KAUST) in Saudi Arabia developed GaN and InGan red microLED devices that are highly efficient.

The researchers managed to increase the efficiency of their previous design by a new chemical treatment that removes damages at the microLED sidewalls (created during the fabrication process) and also retains the high crystal quality at the InGaN and GaN sidewall interfaces.

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 details 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.

Ennostar to gradually upgrade its Taiwanese LED facilities to microLED production

In 2020 Taiwan's LED developers Epistar and Lextar announced plans to establish a joint holding company, effectively merging the two companies, into Ennostar Incorporation.

During a recent investor conferences, Ennostar's CEO said that Epistar will gradually upgrade its miniLED production line in Taiwan to produce microLED chips. The plan is to reach a yearly capacity of over 400,000 6" microLED wafers. In the long term the company will focus its microLED production in Taiwan, while its Chinese factories will produce miniLEDs.

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.

STRATACACHE to build the first MicroLED production line in the US, mass production expected by 2023

Global digital signage solution provider STRATACACHE is embarking on a project to construct a microLED display production line in Eugene, Oregon. The company aims to start production in this fab at around 2022-2023, with plans to adopt these microLED displays in its own solutions.

The new factory (E4) will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly. The company plans to produce a wide range of displays, from tablet-sized panels to large-area displays. Some of these displays will be flexible and transparent as the company sees a market demand for such technologies. The yearly capacity of the E4 is expected to start at a 1 million square meters per year.
