Infineon Technologies AG has been nominated for the Deutscher Zukunftspreis 2024, the Federal President’s Award for Technology and Innovation, for its development of a new type of energy-saving chip based on the innovative semiconductor material silicon carbide (SiC). The Jury of Deutscher Zukunftspreis has announced the three nominated teams in Munich.
A team of developers from Infineon, together with Chemnitz University of Technology, has succeeded in developing the world’s first silicon carbide MOSFET with a vertical channel (trench MOSFET) and innovative copper contacting in the 3300V voltage class. The new SiC modules and the power converters equipped with the modules represent a revolutionary innovation leap in semiconductor technology from conventional silicon to more energy-efficient silicon carbide, which reduces switching losses in high-current applications by 90%.
MOSFETs are electrical switches for a wide range of applications. Trench MOSFETs differ from so-called planar MOSFETs in their cell structure and performance. While the current flow in planar MOSFETs is initially horizontal, trench MOSFETs offer purely vertical channels. This results in a higher cell density per surface area, which in turn significantly reduces the losses in the chip during energy conversion and therefore increases efficiency.
“The transition towards green energy and many other pressing challenges of our time can only be solved with technological progress,” said Jochen Hanebeck, CEO of Infineon Technologies AG. “It is therefore important to promote and reward innovation and make it visible in society. The ‘Deutscher Zukunftspreis’ is the most important national award that is presented with this aim in mind. The nomination is a great honor for us and proof of the successful research and development work at Infineon. Congratulations to all colleagues involved!”
The CoolSiC™ XHP™2 module family enables significant energy savings, for example in industrial power generation in solar parks or wind turbines, in power transmission and, above all, in end consumption, where high energies in the megawatt range are required. A single train with a silicon carbide drive system can save around 300 MWh per year compared to the previous silicon-based solution. This is roughly equivalent to the annual consumption of 100 single-family homes. Together with drive technology manufacturers and rail operators, Infineon is making an important contribution to decarbonization. At the same time, local residents also benefit from the lower noise level of trains with SiC modules when they pass through residential areas.
Through numerous innovative developments in chip processing and design as well as contacting and module technology, the team led by Dr. Konrad Schraml, Dr. Caspar Leendertz (both Infineon) and Prof. Dr. Thomas Basler (Chemnitz University of Technology) has brought the 3300V CoolSiC XHP2 high-performance module to production readiness. With ten times greater reliability against thermomechanical stress and a significantly higher power density compared to silicon modules, the new silicon carbide module can also be used to electrify large drives in diesel locomotives, agricultural and construction machinery, aircraft and ships, which were previously reserved for fossil fuels. The significantly higher switching frequencies permitted by the new module are helpful, as they enable a significant reduction in weight and volume of the power converters in the application.
“This nomination shows that climate change and sustainable resource consumption have become central aspects of our society,” said Dr. Peter Wawer, Division President Green Industrial Power (GIP) at Infineon. “Innovative energy solutions and power semiconductors are a core component in decarbonization and fighting climate change, as the expert jury of Deutscher Zukunftspreis has recognized. I am proud that we at Infineon can make a significant contribution to a green future with pioneering technology.”
Project manager Dr. Konrad Schraml: “For us as a development team, it is a matter close to our hearts to develop innovative chips that contribute to efficient energy consumption and thus also to green mobility on our planet. This nomination is a great recognition for my team, whose tireless efforts, expertise and passion for sustainability have made the technology breakthrough in silicon carbide possible.”
On November 27, Federal President Frank-Walter Steinmeier presents the Deutscher Zukunftspreis to the winning team in Berlin.

Shin-Etsu Chemical Co., Ltd. has created a 300-mm (12-inch) QSTTM substrate, which is a substrate dedicated to GaN epitaxial growth, and recently started supplying samples.
Shin-Etsu Chemical has sold 150-mm (6-inch) and 200-mm (8-inch) QSTTM substrates and GaN on QSTTM epitaxial substrates of each diameter. Meanwhile, the company worked on further increasing the diameter in response to strong customer demand and successfully developed a 300-mm (12-inch) QSTTM substrate. GaN device manufacturers cannot benefit from increasing the diameter of materials because of the lack in large-diameter substrate suitable for GaN growth, despite the fact that they can use the existing Si production line for GaN.
This 300-mm QSTTM substrate enables GaN epitaxial growth without warping or cracks, which was unattainable on Si substrates, thus significantly reducing device costs. In addition to the enhancement of facilities for 150-mm and 200-mm QSTTM substrates already in progress, Shin-Etsu Chemical will work on mass-producing 300-mm QSTTM substrates.
Since QSTTM substrates have the same coefficient of thermal expansion as that of GaN, it is possible to constrain warping and cracks of GaN epitaxial layer on QSTTM substrate of the SEMI standard thickness. This substrate material allows for high-quality and thick GaN epitaxial growth with a large diameter. Leveraging this feature, many customers are evaluating QSTTM substrates and GaN on QSTTM epitaxial substrates for power devices, high-frequency devices, and LEDs. Despite the challenging business environment, customers have entered the development phase toward practical to address the recently increasing interest in power devices, including power supplies for data centers.
The addition of the 300-mm QSTTM substrate to the lineup of the 150-mm and 200-mm can significantly accelerate the spread of GaN devices. Shin-Etsu Chemical is committed to contribute to the realization of a sustainable society where energy can be used efficiently through the social implementation of GaN devices.

Infineon has secured design wins with a total value of approximately five billion euros and has received approximately one billion euros in prepayments from existing and new customers for the ongoing expansion of the Kulim 3 fab. Notably, these design wins include six OEMs in the automotive sector as well as customers in the renewable energy and industrial segments.
Kulim 3 will be closely connected to the Infineon site in Villach, Austria, Infineon’s global competence center for power semiconductors. Infineon already increased capacity for SiC and GaN power semiconductors in Villach in 2023. As “One Virtual Fab” for wide-bandgap technologies, both manufacturing sites now share technologies and processes which allow for fast ramping and smooth and highly efficient operation. The project also offers a high grade of resilience and flexibility, which will ultimately benefit Infineon’s customers.
The expansion will benefit from the excellent economies of scale already achieved for 200-millimeter manufacturing in Kulim. It will complement Infineon’s leading position in silicon, based on 300-millimeter manufacturing in Villach and Dresden. Thus, Infineon is strengthening its technological leadership across the entire spectrum of power semiconductors, in silicon as well as SiC and GaN.
In addition, the investment in wide-bandgap capacity in Kulim strengthens the local ecosystem and proves that Infineon is a reliable partner within the growing semiconductor hub Malaysia. Infineon’s operations in Malaysia started as early as 1973 in Melaka. In 2006, the company opened Asia’s first frontend fab in Kulim. Currently, Infineon employs more than 16.000 highly skilled people in Malaysia.
The Kulim 3 fab will be powered by 100% green electricity and will employ the latest energy efficiency measures to support Infineon’s goal of carbon neutrality. To avoid emissions, Infineon will use a state-of-the-art abatement system and green refrigerants that combine high efficiency with extremely low global warming potential. Other measures to ensure sustainable operations include state-of-the-art recycling of indirect materials and state-of-the-art water efficiency and recycling processes.
