Europe is home to a vibrant ecosystem of (hidden) champions, from traditional enterprises in vertical markets, to SMEs and start-ups the competitive advantages of which lie in superior semiconductor-based solutions. Nevertheless, many of these companies are currently confronted with limited access to advanced semiconductor technologies, while at the same time these technologies are increasingly becoming the most important factor for innovation and market growth.

The European Commission is investing significant resources under the EU Chips Act to strengthen semiconductor technologies and applications in the European Union. This aims to enhance Europe’s technological resilience, secure supply and value chains, and drive innovation in emerging fields such as energy efficient AI, manufacturing, mobility, information and communications, neuromorphic and quantum computing as well as trusted and sustainable electronics.

The APECS pilot line focuses on bridging application-oriented research with innovative developments in heterogeneous integration*, in particular emerging chiplet** technologies. By pushing beyond conventional system-in-package (SiP) methods, APECS will deliver robust and trusted heterogeneous systems, significantly boosting the innovation capacity of the European semiconductor industry.

Investments in strategic projects such as APECS under the EU Chips Act, is crucial for positioning Europe as an indispensable partner in the global technology sector. Germany plays a key role in this endeavor – both as a leading research hub and a driving economic force. Thanks to substantial funding from the German Federal Ministry of Education and Research (BMBF) and the federal states of Saxony, Berlin, Bavaria, Schleswig-Holstein, Baden-Württemberg, North Rhine-Westphalia, Brandenburg, and Saxony-Anhalt, it will be possible to further expand the R&D infrastructure in the coming years within the framework of the APECS pilot line. This represents a crucial step toward ensuring the long-term economic stability of both Germany and Europe.

“Fraunhofer plays a central role in the implementation of major projects such as APECS, which strengthen Germany's technological resilience and capacity for innovation,” emphasizes Prof. Holger Hanselka, President of the Fraunhofer-Gesellschaft. “With our practice-oriented research and close collaboration with industry, academia, and political partners, we lay the foundation not only for developing cutting-edge technologies but also for bringing them into industrial application. APECS is an example how to connect research with business – it underscores how close cooperation with ministries and other partners can secure Europe´s position in the global microelectronics market.”

Innovation where European industries need it the most

The APECS pilot line will play a key role in supporting European microelectronics by developing new system integration technologies and unlocking new functionalities within the system-technology co-optimization (STCO) approach. This will enable European companies to develop advanced products, even in low quantities, at competitive costs. By providing a wide range of technologies on a single platform, APECS is positioned to become Europe’s leading hub for the development of advanced packaging and heterogeneous integration.

APECS will be a key driver of collaboration among European RTOs, industry and academia, fostering a lively innovation ecosystem. Customers will benefit from a single point of contact to the APECS pilot line. APECS will cover end-to-end design and pilot production capabilities and accelerate progress from cutting-edge research to practical, scalable manufacturing solutions.

Furthermore, APECS will play a pivotal role in Europe's transition towards a carbon-neutral and circular economy through its promotion on eco-design and green manufacturing initiatives.

Boosting Innovation through strong multilevel Collaboration

The APECS pilot line builds on the structures established by the Research Fab Microelectronics Germany (FMD). In Germany, twelve institutes from the Fraunhofer Group for Microelectronics and the two Leibniz institutes FBH and IHP participate in APECS. The work is led by the central office in Berlin.

Prof. Albert Heuberger, spokesman of the Fraunhofer Group for Microelectronics and chairman of the FMD, emphasizes: “The success of the EU Chips Act relies on strong partnerships. For years, the FMD has successfully combined the strengths of decentralized research institutions with the collaborative potential of a centralized microelectronics hub. This clearly illustrates how APECS is set to become a long-term accessible pilot line for all European stakeholders across the entire value chain. Together with the other EU Chips Act pilot lines, APECS will be a crucial component for heterogeneous integration and advanced packaging of the envisioned pan-European pilot line facility – and thus an indispensable instrument of EU Chips Act.”

The APECS consortium brings together the technological competences, infrastructure, and know-how of ten partners from eight European countries: Germany (Fraunhofer-Gesellschaft as coordinator, FBH, IHP), Austria (TU Graz), Finland (VTT), Belgium (imec), France (CEA-Leti), Greece (FORTH), Spain (IMB-CNM, CSIC) and Portugal (INL). APECS is coordinated by the Fraunhofer-Gesellschaft and implemented by the Research Fab Microelectronics Germany (FMD).

Fraunhofer IPMS plays a pivotal role

Fraunhofer IPMS plays a pivotal role in the APECS pilot line and is set to advance the project's objectives in chiplet design and integration technology. One part covers the chiplet system design, where we will setup advanced system architectures for computing, artificial intelligence and MEMS sensors/actuators. The second large part covers innovative chiplet (Back-end-of-line) integration technologies, including 3D stacking and 2.5D wafer-level integration, functional interposers with ultra-high density, and the use of CMOS and MEMS/non-silicon chiplets. One main part of our contribution is the development of quasi monolithic integration (QMI), which will set new benchmarks in chiplet integration technology.
