ALLOS Semiconductors GmbH

ALLOS Semiconductors is the global leader in 200 mm and 300 mm GaN‑on‑Si epiwafer technology for next‑generation microLED applications. Our proprietary MOCVD‑based approach delivers high‑yield, cost‑effective GaN‑on‑Si epiwafers that can be processed in the same standard silicon semiconductor fabs/lines as silicon wafers—unlocking true scalability.

Our customers use ALLOS epiwafers in two distinct, fast‑growing markets:

• MicroLED displays, where ultra‑bright, power‑efficient microLEDs enable breakthrough AR and outdoor display performance in compact form factors.
• Optical Interconnects (OI), where microLEDs act as fast, energy‑efficient light sources for short‑reach, photon‑based chip‑to‑chip communication—critical as AI systems scale and electron‑based interconnects reach their limits.

Founded in 2014 and headquartered in Dresden, ALLOS operates fabless through leading contract manufacturers worldwide and holds ~100 granted and pending patents.
