Revolutionizing Technology: Dr. Asselberghs Leads Graphene Manufacturing in Europe
Dr. Inge Asselberghs has spent the last ten years studying graphene. She leads EU-funded efforts to bring this remarkable material into practical applications. Dr. Asselberghs works with an international team at Imec, a nanoelectronics research institute in Leuven, Belgium. They opened a prototype manufacturing facility for graphene and other 2D materials.
This team combines expertise from 11 universities, research institutes, and companies across six European countries. Their project is called the 2D experimental pilot line (2D-EPL). The goal is to enhance the production and use of graphene in electronics, photonics, and sensors.
Graphene is a single layer of carbon atoms. It is incredibly thin, strong, light, and flexible. It effectively conducts heat and electricity, making it suitable for various advanced products, including batteries and space technology.
“The hype started as soon as graphene was discovered,” says Dr. Asselberghs. Recognizing its economic potential, the EU launched the Graphene Flagship initiative in 2013, uniting 178 partners with a €1 billion budget to boost research. The 2D-EPL project is part of this initiative.
The aim of the pilot line is to accelerate the use of graphene for producing new prototypes in electronics and other fields. This step is vital before full-scale production can begin. “Our first goal was to make graphene devices on a wafer scale using existing automated processes,” says Dr. Asselberghs. Wafers are thin disks of material commonly used in electronics.
Manufacturing graphene is challenging. Its thinness makes it susceptible to defects. Even a small amount of dust can cause problems. During production, graphene needs a protective polymer layer and must be transferred to a silicon base carefully. Creating an automated process for this was difficult.

Q: Dr. Asselberghs, you have dedicated a decade to studying graphene. What initially drew you to this remarkable material?
Dr. Inge Asselberghs: The moment graphene was discovered, the hype surrounding it was palpable. It’s a single layer of carbon atoms with remarkable properties—flexible, lightweight, yet incredibly strong. The potential applications in electronics, photonics, and sensors were too compelling to ignore.the economic possibilities were also significant, prompting initiatives from organizations like the EU.
Q: Can you elaborate on the EU’s Graphene Flagship initiative and your role within it?
Dr.Asselberghs: Absolutely. Launched in 2013, the Graphene Flagship initiative is a massive collaboration involving 178 partners and a budget of €1 billion designed to accelerate research and innovation in graphene technologies. Within this framework,I lead the 2D experimental pilot line (2D-EPL) project at Imec,where we focus on developing the manufacturing capabilities for graphene and other 2D materials.
Q: What are the primary goals of the 2D-EPL project?
Dr. Asselberghs: Our main aim is to enhance the production and use of graphene,particularly for creating new prototypes in various fields such as electronics. We’re focusing on producing graphene devices on a wafer scale using state-of-the-art automated processes—an essential step before we can move to full-scale production.
Q: What challenges do you encounter in manufacturing graphene?
Dr. Asselberghs: Manufacturing graphene is intricate due to its extreme thinness. Even the slightest contamination, like a speck of dust, can introduce defects.We require a protective polymer layer during production, and the transfer process to a silicon base must be executed with utmost care. Developing a reliable automated process for this has proven to be a significant challenge.
Q: How does your facility at Imec accommodate these production needs?
Dr. Asselberghs: Our assembly line is designed to handle 200 or 300mm wafers, which are standard sizes in silicon manufacturing. We collaborate closely with various partners who contribute their expertise and tools to ensure the quality and efficiency of graphene production, aiming to produce high-quality material suitable for industry use.
Q: Europe appears to be at the forefront of graphene research. What factors contribute to this advantage?
Dr.Asselberghs: Europe is in a strong position, largely due to sustained governmental and institutional funding for graphene and 2D material research. this consistent support allows us to innovate continuously and keep our research aligned with industry needs, making Europe a leader in developing these advanced materials.
Q: What are some aspirations for graphene in practical applications?
Dr. asselberghs: We envision a future where graphene can play a role in creating faster transistors and more efficient data centers, and also advanced sensors that are connected to smartphones.Industries are showing significant interest; we’ve already had several companies approach us with specific design requests, which demonstrates the growing eagerness to explore the capabilities of graphene.
Q: when do you foresee graphene becoming commercially viable?
Dr. Asselberghs: While graphene isn’t ready for widespread industrial use just yet, we’re working diligently towards that goal. The path to affordable mass production of advanced electronics and sensors is being paved, and we are confident that graphene will soon take its place in the market, revolutionizing technology as we certainly know it.
At Imec, an assembly line processes 200 or 300mm wafers, sizes familiar to silicon manufacturing. Collaborating partners contribute tools and expertise to achieve high-quality graphene production.
Europe leads in developing graphene and 2D materials. “We are in a strong position in Europe because of consistent funding for this research,” notes Harm Knoops from Oxford Instruments Plasma Technology. The excitement extends beyond graphene to other thin materials that can work as semiconductors.
Industries are eager to explore these materials. Several companies have approached the research team with specific design requests.
A key advantage of graphene is that it consists of carbon, one of Earth’s most common elements. Researchers aim for affordable mass production of advanced electronics and sensors. They hope to create devices that are not yet available.
While graphene is not ready for widespread industrial use, it will reach the market eventually. It could lead to faster transistors, efficient data centers, or advanced sensors connected to smartphones.
