Infineon's €5 Billion Dresden Mega-Fab Goes Live Ahead of Schedule

Infineon opened the doors to its new smart power semiconductor factory in Dresden, Germany on Thursday — months ahead of the original schedule and carrying a €5 billion price tag.

The facility, called the Smart Power Fab, doubles Infineon’s production capacity at its Dresden campus. It’s now the world’s largest manufacturing base for smart power semiconductors and analog/mixed-signal chips. The €5 billion investment is the largest single outlay in the company’s history.

“New factory is coming online at exactly the right time,” CEO Jochen Hanebeck said. “The Smart Power Fab is providing much-needed capacity for key technologies — from powering AI data centers to software-defined vehicles to renewable energy.”

The plant runs on digital twin technology and artificial intelligence to manage production. Infineon says these tools let it ramp up capacity twice as fast as previous-generation fabs, giving it more flexibility to respond to shifts in market demand.

Global demand for power semiconductors has surged alongside the buildout of AI infrastructure, electric vehicles, and renewable energy systems. These chips handle voltage regulation and power conversion — the kind of unglamorous but essential work that happens inside everything from server racks to car inverters.

Infineon also closed an acquisition in January, buying ams OSRAM’s non-optical analog and mixed-signal sensor business. Roughly 230 employees from ams OSRAM joined Infineon as part of the deal. The acquired operations are expected to bring in about €230 million in revenue this year.

The Dresden expansion is one of the largest results of Europe’s push to build out domestic chip manufacturing. Germany has poured billions into attracting and expanding semiconductor production under its European Chips Act funding, and Infineon’s new fab is a centerpiece of that strategy.
