Infineon surfs the automotive wave
Infineon increased its revenues by 29 percent and tripled its profits, driven by power and automotive

"We are more powerful than ever, have achieved 11 billion euros in sales for the first time in a financial year and have significantly increased profitability," said Dr Reinhard Ploss, Infineon's CEO at the annual results. The company's strategy of focusing fully on the trends of electrification and digitalisation has paid off. 

"In view of the continuing high demand for semiconductors for the energy-efficient and connected world, we expect a strong 2022 financial year," he dded.

At the same time, he announced increased investments and an expansion of production capacities for the innovative semiconductor technologies silicon carbide and gallium nitride, but also for conventional silicon products. According to current plans, the company intends to invest €2.4 billion in the 2022 financial year; the focus will be on expanding front-end manufacturing. Only recently, the company opened another production line for power semiconductors in Austria. In addition, Ploss said Infineon intends to "pull out all the stops" to secure additional capacity from contract manufacturers as well.

The special attention of Infineon's developers is currently focused on SiC technology. Here, Infineon not only wants to expand its capacities, the company has also improved its technology. Ploss presented the extraction of wafers from SiC cylinders as an example: In the conventional method of sawing the wafers out of these raw matetrial blocks, up to 75% of the expensive raw material is lost, Ploss said. The cold split process developed by Infineon reduces these losses quite considerably. "This brings very significant cost advantages," Ploss explained. A first product manufactured using this technique is just about to be released for production, he said.


In the recently completed fourth quarter of the 2021 fiscal year, group revenue was up 10 percent to €3.007 billion. In this quarter, revenue growth for products in the Power & Sensor Systems (PSS) segment even exceeded that of products for
