Infineon Technologies AG holds an important position in the European semiconductor industry, with a focus on energy conversion, electronic control and secure equipment connectivity. Based in Neubiberg, near Munich, the German group supplies components that are generally invisible to end users but necessary for the operation of vehicles, industrial machinery and everyday devices. Its corporate website is available at infineon.com.
From Siemens to a specialized group
Infineon was founded in 1999 through the spin-off of Siemens’ semiconductor operations, before going public in 2000. These industrial origins explain its strong focus on components for embedded systems and electrical equipment, rather than general-purpose processors for computers and smartphones. The company is listed in Frankfurt and is part of the DAX index.
Its development combines industrial investment and acquisitions. The acquisition of the US company International Rectifier, completed in 2015, strengthened its expertise in power semiconductors. Its acquisition of Cypress Semiconductor, completed in 2020, notably expanded its offering in microcontrollers, memory and connectivity. These transactions enable Infineon to offer more complementary building blocks for designing electronic systems, beyond supplying individual components.
Power, automotive and connected systems
Power electronics is a core area of its business. Infineon’s components are used to convert, switch and manage electricity in power supplies, motors, charging stations and solar installations. In addition to silicon, the group develops technologies based on silicon carbide and gallium nitride. Depending on the application, these materials help reduce energy losses and enable more compact system designs.
The automotive sector is another major market. Infineon supplies components for electric traction, battery management, vehicle body functions and driver assistance systems. Its microcontrollers control embedded functions, while its sensors measure various physical quantities. The group also offers connectivity and hardware security solutions for connected devices, identity documents and electronic transactions.
Infineon has its own manufacturing capabilities, notably in Germany, Austria and Malaysia, while also working with industrial partners. This footprint gives it direct control over some of its processes, but requires substantial investment and careful management of demand cycles.
What’s next?
Infineon’s prospects remain tied to the electrification of end uses and the pursuit of energy efficiency, including in data centers. However, realizing this potential depends on the pace of electric vehicle adoption, industrial spending and the balance between production capacity and orders. In the face of international competition, the challenge will be to turn its technological advances into competitive, readily available products qualified by customers. Geographic diversification of production and securing supplies also remain key strategic issues.
