Infineon Technologies

Infineon Technologies AG is a German company which designs and manufactures semiconductor devices. It provides parts for automotive, power and security systems. In 2023, Infineon was Germany's largest chip manufacturer, and had roughly 57,000 employees in 2025.

Infineon was spun-off from Siemens, a German engineering conglomerate in April 1999; one year later, it underwent the largest initial public offering (IPO) for a tech company to date despite Siemens retaining a 74 percent stake in the business. By 2026, Infineon's operations had been restructured into three distinct business areas: Automotive (ATV), Power Systems (PS) and Edge Systems (ES). According to Handelsblatt, Infineon is Germany’s largest semiconductor manufacturer and ranks among the top ten semiconductor manufacturers worldwide.
