ALLOS Semiconductors is a leading supplier of GaN‑on‑silicon epiwafers for microLEDs.

These high-tech materials enable breakthroughs at the foundation of the artificial intelligence (AI) megatrend.

Products for two AI Driven Markets

ALLOS provides specialized materials for two areas of rapidly growing strategic importance for AI hardware. Our global customers use these materials to develop next-generation solutions in both fields:

MicroLED based optical interconnects for AI computing

Conventional copper interconnects become increasingly a performance and energy-efficiency bottleneck for AI computing. The solution is to transition to photon-based communication technologies, even at the chip level. MicroLEDs based on ALLOS’ materials are ideal for this purpose as they combine high bandwidth, low energy consumption and long-term reliability.

MicroLED displays as visual user interfaces to AI systems

The next generation of displays, especially augmented reality (AR) displays, will provide users with seamless AI-generated contextual information without relying on traditional hardware such as smartphones or PCs. MicroLED displays based on ALLOS’ materials are uniquely positioned for this purpose, as they combine the required AR and outdoor display performance breakthroughs with high manufacturing yield and low unit cost.

With 98 % of the entire epiwafer area being on target, ALLOS already today achieves industry leading color uniformity.

Silicon Fab-
Compatibility

200 mm
300 mm

All our materials are fully silicon fab-compatible and are available in both 200 mm and 300 mm wafer diameters. This enables microLED device manufacturing in existing silicon fabs, including the usage of technologies such as advanced wafer-to-wafer bonding. Our customers are therefore in a unique strategic position to benefit from the quality, yield, cost, throughput and scaling advantages of the silicon semiconductor industry.

Fabless, Globally Connected & Customer‑Focused since 2014

ALLOS operates fabless, leveraging a global network of qualified contract manufacturers and specialist suppliers. This allows us to respond quickly to fast-growing markets and to offer flexible scaling options, including onshoring and on-site manufacturing.

Our international team of experienced experts works at the leading edge of microLED materials research and product development. Our products are protected by a growing IP portfolio of close to 100 patents.
