International Diversity and Technological Excellence: Insights into Infineon’s Linz Research Center

Infineon Technologies Austria AG is part of the extensive Infineon network, which comprises 80 locations worldwide and more than 55,000 employees. At the Linz site, approximately 180 employees from more than 28 countries work in the field of high-frequency technology. Due to its proximity to Johannes Kepler University, numerous research institutions, and the industrial environment, the site is ideally suited to the needs of Infineon as one of Austria’s leading research-intensive companies. The City of Linz’s Department of Economy and Innovation met with Manfred Ruhmer, who is responsible for managing the R&D ecosystem and serves as the local representative at the Linz site.

Decarbonization and Digitalization as Guiding Principles

When asked what Infineon Linz stands for, Ruhmer replies: “That’s a very, very good question. It’s difficult to answer in a single sentence. When you walk into our building, there’s a large slogan: ‘Decarbonization and Digitalization together.’ That is the motto we stand for, because we believe that decarbonization is becoming even more important in times like these. Where there are global climate issues, we can make a real positive impact with our products. At the same time, digitalization is an absolute driver of decarbonization. We can also contribute a great deal in this area with our products, which is why we need innovative strength in both fields.

That is exactly what we stand for!”When asked what Infineon Linz stands for, Ruhmer replies: “When you enter our building, you’ll have noticed our slogan: ‘Decarbonization and Digitalization, together!’ Given the current climate crisis, it’s absolutely essential to use energy-efficient products to squeeze out even the last percentage point of efficiency. At the same time, we are driving digitalization with our products, for example by having our sensors bridge the gap between the analog and digital worlds. That’s why we need innovative strength in both areas. That’s exactly what we stand for!”

Radar Sensors and High-Tech Components from Linz

At the Linz site, approximately 180 employees develop products in the high-frequency range. These include, for example, 77 GHz radar sensors used in modern vehicles to enable features such as adaptive cruise control with automatic speed adjustment, which makes driving safer and more comfortable. According to Ruhmer, the technology has now advanced to the point where radar sensors in automotive applications can look not only forward but also into blind spots and backward—for example, when parking or to detect potential hazards.

In addition to radar sensors, components such as antenna tuners and so-called “low-noise amplifiers” are also developed in Linz; these ensure better reception in smartphones, for example, even in underground parking garages where weak signals must be amplified to enable clear voice transmission. With a smile, Manfred Ruhmer explains, “These chips are now smaller than 1x1 mm,” making them barely visible to the naked eye, when asked if he can show us one of the products developed by Infineon Technologies in Linz.

Linz Plays in the “Champions League”

Although many hardware manufacturers are now based in Asia, Infineon Technologies Austria is proud to remain one of the few European manufacturers still competing in the “Champions League” and driving technological development forward. Infineon is a leader in Austria, particularly in the development and production of energy-saving chips, which are especially relevant for the rapidly growing AI data centers. But the global demand for radar technology—for example, for self-driving taxis—also demonstrates how relevant and forward-looking the developments from Linz are. “Most cars and smartphones contain components featuring Infineon technology,” Ruhmer describes with visible pride.

STEM Promotion and Social Responsibility

Social and environmental aspects are also important: Infineon is strongly committed to STEM initiatives and advocates for greater diversity. Women currently make up 21 percent of the workforce, with a long-term goal of reaching 50 percent. “The workplaces are modern and diverse, characterized by international collaboration and interdisciplinary communication. The corporate culture is open and inclusive—regardless of gender, background, or language.

The team consists of people from a wide variety of nations and disciplines, which actually leads to measurably better results and innovations,” notes Manfred Ruhmer. Infineon Linz sees itself as a role model for diversity in action and as a driving force for social cohesion, especially in times of increasing polarization. This combination of innovation, global networking, and social responsibility makes the site an attractive and sustainable employer and a true pioneer in innovation in Linz.
