Graphene Flagship discusses graphene’s potential in semiconductor innovation
As the semiconductor industry approaches the physical and economic limits of silicon, there is increasing focus on advanced materials that will enable the next generation of electronic and photonic systems. Among them, graphene has long stood out for its outstanding electrical and thermal properties. But translating that promise into manufacturable semiconductor technology will require a large, coordinated effort.
At the heart of Europe’s response is the Graphene Flagship, which has spent more than a decade building the scientific, technological and industrial infrastructure needed to bring graphene and related two-dimensional (2D) materials into real-world applications. The effort reflects a broader shift in semiconductor innovation from single-material solutions to heterogeneous integration across complex material platforms.
Beyond silicon: redefining semiconductor materials
Graphene’s appeal lies in its extraordinary carrier mobility, mechanical flexibility, and thermal conductivity. These properties make them very attractive for high-frequency electronics, photonics, and advanced sensing applications.
But graphene doesn’t inherently behave like a traditional semiconductor. Because there is no inherent bandgap, the current cannot be turned off in the way digital logic requires. Rather than limiting its potential, this property has reshaped graphene’s position in the semiconductor industry.
Rather than serving as a direct replacement for silicon, graphene is currently being developed as a complementary material that can improve performance and enable new device architectures, especially when integrated with other 2D materials with band gaps.
From research to industry
The central challenge for graphene was not to demonstrate its properties, but to incorporate it within a highly optimized, capital-intensive semiconductor manufacturing infrastructure.
Here, the graphene flagship made a decisive intervention. By aligning academic research with industrial requirements, we have focused on scalability, reproducibility, and process compatibility, which are key criteria for adoption in the semiconductor value chain.
This effort brings together stakeholders across the innovation ecosystem, including material suppliers, equipment manufacturers, semiconductor foundries, and end users. This integrated approach ensures that development is based on real industrial needs rather than being limited to a laboratory environment.
2D Pilot Line: A vital bridge to industry
At the heart of this transition is the 2D Pilot Line (2D-PL). This is probably one of the most strategically important achievements of the graphene flagship to date.
2D-PL is designed to address a long-standing bottleneck in advanced materials innovation: the gap between proof-of-concept research and industrial-scale manufacturing. For the semiconductor industry, this gap is especially acute given the stringent requirements for yield, uniformity, and integration with existing CMOS processes.
2D-PL directly addresses these challenges by providing:
Wafer-scale integration capabilities for graphene and related 2D materials. Process modules compatible with CMOS manufacturing allow seamless insertion into existing production lines. Access to prototyping infrastructure allows companies to test and validate devices before embarking on full-scale manufacturing. A collaboration platform connecting research institutes and industrial partners across Europe.
In fact, 2D-PL serves as a pre-industrial environment in which technology can mature to a level suitable for commercial deployment.
For semiconductor stakeholders, this represents a significant value proposition. Rather than investing in entirely new infrastructure, companies can explore graphene-enabled technologies within a framework that aligns with established manufacturing paradigms. This reduces both technical risk and time to market.
Beyond the graphene platform
The importance of 2D-PL goes beyond graphene. Supports the integration of a broader family of 2D materials, including transition metal dichalcogenides (TMDs) and other engineered compounds.
These materials will expand the portfolio of projects and, by exploiting the unique properties of such complex but atomically thin structures, new devices with a wider range of applications will emerge. Graphene offers fast charge transport and thermal management, while TMDs offer classic semiconductor switching behavior and excellent mechanical and electrical properties. The adoption of diverse 2D materials is increasingly considered essential for next-generation semiconductor devices, especially in areas such as photonics, edge computing, and advanced sensing systems.
Project-driven innovation
In parallel with infrastructure development, Graphene Flagship continues to advance targeted projects that address specific semiconductor challenges.
The Next-2Digits project focuses on the scalable integration of graphene into semiconductor platforms, and GATEPOST is researching graphene-enabled photonic components for ultra-high-speed data processing. Other efforts, such as 2DNeuralVision and 2DSPIN-TECH, are pushing the boundaries of computing architectures, from optical neural networks to spin-based electronics.
These projects collectively demonstrate how graphene and related materials can move beyond incremental improvements and enable entirely new technology paradigms.
Strategic impact on Europe
The development of 2D-PL also has broader strategic importance. As global competition for semiconductors intensifies, Europe is seeking to strengthen its technological sovereignty and reduce its dependence on external supply chains.
By investing in cutting-edge materials and pilot-scale manufacturing capabilities, Graphene Flagship will help:
Building a resilient European semiconductor ecosystem. Supporting innovation-driven industrial growth. Positioning Europe at the forefront of next generation electronics.
In this context, graphene is not just a material innovation, but part of a broader strategy to ensure long-term competitiveness in key technologies.
Looking to the future
Although challenges remain, particularly in bandgap engineering, large-scale material quality, and cost competitiveness, the direction is clear. Graphene is moving from a research material to an enabling technology within the broader semiconductor framework.
The 2D pilot line exemplifies this change. By providing a path from discovery to deployment, we will help unlock the practical value of graphene for industry.
For those in the semiconductor industry, the message is becoming increasingly clear: the future will not be determined by silicon alone. Instead, they are formed by integrating multiple advanced materials that work together to deliver performance improvements that cannot be achieved with any single material alone.
Through initiatives such as the Graphene Flagship and its projects, that future is already starting to take shape.
