Black Simiconduktor, f.l.t.r.: Sebastian Schall, Dr.Daniel Schall
The 2026 Aachen Engineering Prize has been awarded to Black Semiconductor founders Dr Daniel Schall and Sebastian Schall – a milestone for the region’s microelectronics sector.
The next generation of computer chips is being shaped to a significant extent in Aachen. We are delighted that this year’s Aachen Engineering Prize is being awarded to two visionaries whose careers are closely linked to the excellent research carried out at our Faculty of Electrical Engineering and Information Technology: Dr Daniel Schall and Sebastian Schall, founders of the start-up Black Semiconductor.
The technological foundation for this success is a groundbreaking innovation in graphene photonics. Whilst conventional semiconductor architectures are increasingly reaching their limits due to heat generation and limited bandwidths in data transmission, the Schalls are pursuing a new approach: instead of sending data exclusively via electrical conductors, they enable direct conversion into optical signals on the chip. By integrating graphene, a material with outstanding physical properties, they have succeeded in combining electrical and optical functions directly on a single wafer.
“This innovative approach addresses key performance and efficiency limitations of existing semiconductor architectures and makes a decisive contribution to the next generation of high-performance and AI systems,” emphasises the Advisory Board of the Aachen Engineering Prize in its statement.
For our faculty, this development is an outstanding example of how fundamental scientific research is translated into industrial leadership. Dr Daniel Schall, himself a micro-systems engineer with a PhD and strong links to Aachen’s research community, laid the foundations for this technology during his time at the AMO GmbH research institute. The successful transfer from research to a company that now employs over 130 people impressively demonstrates the added value of the close integration between RWTH teaching and applied research.
Black Semiconductor is now building a 15,000-square-metre production facility, ‘FabONE’, in the Rothe Erde district of Aachen to manufacture graphene chips on an industrially relevant scale. This project not only strengthens the European semiconductor industry in competition with global players, but also underlines Aachen’s role as an innovation hub for future technologies. In doing so, the founders are consistently focusing on CMOS compatibility, enabling their innovation to be seamlessly integrated into existing industrial manufacturing processes.
“Black Semiconductor is making a lasting contribution to strengthening Europe’s position as a centre for the semiconductor industry through its close collaboration with the research sector and its industrial focus. The company thus embodies innovation-driven engineering excellence in a unique way,” explains Rector Professor Ulrich Rüdiger. The City of Aachen, represented by Lord Mayor Dr Michael Ziemons, also emphasises the strategic importance of this development: “We are proud that this forward-looking company has chosen to base itself in Aachen.”
The award ceremony for the Aachen Engineering Prize will take place on 5 September 2026 at 7 pm in the Coronation Hall of the Town Hall. The prize, established by the Association of German Engineers (VDI), is awarded annually to individuals who have made a significant contribution to the advancement of engineering.
