Aixtron SE is a Germany-based technology company specializing in the development, production and sale of deposition equipment used in the manufacture of advanced semiconductor materials. Its core expertise lies in Metal Organic Chemical Vapor Deposition (MOCVD) and Atomic Layer Deposition (ALD) systems, which are critical for producing compound semiconductors such as gallium nitride (GaN) and gallium arsenide (GaAs). These technologies enable the fabrication of light-emitting diodes (LEDs), laser diodes, power electronic devices and RF components.
The company’s product portfolio includes a range of single-wafer and multi-wafer reactors designed for wafer sizes up to 200 millimeters. Aixtron’s MOCVD systems are widely used by LED manufacturers to improve efficiency and color performance, while its ALD platforms support applications in microelectronics, optoelectronics and sensor technologies. The equipment is also used in research and development settings at universities and research institutes working on next-generation semiconductor materials.
Aixtron serves a global customer base with a strong footprint in Asia—particularly in China, Taiwan, South Korea and Japan—Europe and North America. Its regional sales and service teams provide installation, maintenance and process support to ensure optimal system performance and yield. Through local technical centers and global partnerships, Aixtron offers training, spare parts supply and process development services to accelerate customer ramp-up and technology transfers.
Founded in 1983 and headquartered in Herzogenrath, Germany, Aixtron has grown through a combination of internal research efforts and strategic acquisitions to expand its technology portfolio and geographic reach. The company is led by CEO Christian Nickel, who brings extensive experience in the semiconductor equipment industry. Under his leadership, Aixtron continues to focus on innovation in deposition technology, targeting emerging applications such as 5G communications, power electronics for electric vehicles and advanced photonics.
