Infineon Technologies AG
Semiconductors
Infineon's roots run through the entire history of European semiconductors: it began as the semiconductor division of Siemens, was spun off as an independent company in 1999, and is now the world's leading supplier of automotive semiconductors — the chips that manage everything from engine control to airbags to EV power trains. On average, a modern car contains more than a hundred Infineon chips.
The company's technical edge is power: Infineon is the global leader in power semiconductors — the devices that switch and convert electrical power — including IGBTs and silicon carbide (SiC) modules that are essential to electric vehicles, solar inverters, wind turbines, and data center power supplies. It also makes the security chips in passports and payment cards, and radar and MEMS sensors for cars and consumer devices.
With about 58,000 employees and annual revenue near €16 billion, Infineon has ridden the EV and renewable energy booms to record results, and its new SiC factories in Malaysia and Austria are among the largest power semiconductor investments in Europe. For the auto industry, Infineon is a critical dependency — the kind of supplier whose chips are designed into platforms years before production, and whose capacity constraints can ripple through the entire car market.
