ALLOS Semiconductors, based in Dresden, Germany, and established in 2014, is a supplier of GaN‑on‑silicon microLED epiwafers.

ALLOS provides specialized materials for two areas of rapidly growing strategic importance: microLED displays, especially microdisplays, and microLED-based optical interconnects for AI computing. The company's materials are fully silicon fab-compatible and are available in both 200 mm and 300 mm wafer diameters. This enables microLED device manufacturing

In 2017 ALLOS and Veeco demonstrated 200mm GaN-on-Si wafers for micro-LED production. In 2020 ALLOS sold its high-power electronics and RF business to AZUR SPACE to focus its business on the microLED market. In November 2022 we posted a spotlight article on ALLOS Semiconductors. 

US-based Amorphyx develops amorphous-metals based display backplanes, which can be used to drive displays using quantum-tunneling. The company says that such backplanes will enable extremely fast conductivity and thus "unlimited" refresh rates.

Amorphyx's AMNR-based backplane are compatible with LCDs, OLEDs, microLED and e-paper displays.

CEA-Leti is a non-profit research institute based in Grenoble, France. CEA-Leti is one of the world's largest microelectronics and nanotechnology organizations.

Leti develops micro LED displays, with a focus on high-performance microdisplays. Leti has implemented this LED technology to manufacture high-brightness μLED arrays hybridized on silicon circuits. CEA-Leti also developed microLED communication technology.

In 2017 Leti demonstrated the world's first 10-um GaN Microdisplay and in 2019 Leti researchers developed a new CMOS-based process to produce high performance Micro-LED displays. In 2011, Aledia was established as a spin-off from CEA-Leti to develop and commercialize its 3D Nanowire microLED display technology.

US-based Compound Photonics develops high-resolution microdisplay technologies for the AR and MX markets. The company's main products are LCoS displays.

CP used to collaborate with Plessey Semiconductor to apply its display backplane to Plessey's microLED frontplane. Following Plessey's acquisition by Facebook, CP developed its own microLED display technology.

In 2022, Compound Photonics was acquired by Snap.

Founded in 2017 as a spin-off from the university of Turku, Finland, Comptek Solutions develops quantum technology (branded as Kontrox) that boosts the performance of devices such as microLEDs and lasers and makes their manufacturing process easier by solving the problem of aggressive oxidation of compound semiconductor materials.

Kontrox results in a high-quality passivation layer with substantially reduced defect densities that help to greatly decrease the surface recombination phenomena which is a predominant mechanism for such small devices.

Comptek says that MicroLED efficiencies increase significantly with Kontrox, the company has demonstrated up to 250% EQE (external quantum efficiency) improvements.

Crystalwise, established in 2000 in Taiwan, produces hard substrates for semiconductor applications. The company mass produces LiTaO₃, LiNbO₃ substrates for SAW Filter devices and sapphire substrates for blue-white LED epitaxy.

Crsytalwise offers 6-inch polished wafers for Micro-LED growth.

Austria-based FAMETEC, a member of the EBNER Group of companies, produces wafers grown using a McSap (multi net shape c-axis Sapphire boules) process. The company produces high-end 6", 8" and 12" epi-ready sapphire wafers.

FAMETEC produces wafers specifically for microLED growth, and is shipping wafers to a tier-1 Asian microLED developer.

The Fraunhofer Institute for Applied Polymer Research (IAP) develops bio-based and synthetic polymers, from the laboratory to the industrial scale. Applications are diverse across many markets, such as bio-based packaging, lightweight materials, truck tires and more.

The Fraunhofer IAP is active in the display industry, with its IAP functional polymer systems division looking into a broad range of materials, including light-emitting polymers and quantum dots. The focus lies in solution processing of these materials with a strong focus on printing methods.

Specifically for the MicroLED industry, the institute developed quantum dot materials as light converting materials for microLEDs. The IAP participates in the CoCoMe research project that develops printed QD color filters.

FRONICS (Flexible electRONICS) was established in 2016 in Korea as a spin-off from the Korea Advanced Institute of Science and Technology (KAIST) to commercialize smart acoustic sensors and wearable devices.

In February 2018 KAIST announced that FRONICS will also commercialize its new flexible Micro-LED technology.

III-N Technology (or 3N-Tech) was established in 2000 in the US with an aim to develop single-chip power AC-LED devices. The technology can be used to produce micro-LED arrays

III-N Technology's invention evolves from the micro-LED array technology by the same inventors, which was featured on the cover of Compound Semiconductor magazine in November 2000. The micro-LED array consists of several tens of nitride LED devices fabricated on a single semiconductor chip. The emitters can be individually addressed so that the chip acts as a multi-pixel microdisplay.

III-V Lab is a private R&D organisation jointly established by Nokia, Thales and the CEA in France. III-V focuses on III-V semiconductors and has strong competences and established track record in R&D from advanced modeling to transfer to production in the field of III-V SC (GaAs, InP, GaN...).

One of the application areas III-V is developing is LED microdisplays. In May 2017 III-V and LETI demonstrated the world's first WVGA 10-μm pitch GaN microdisplay.
