Hummink Secures €15M To Bring Precision Printing Technology To Chip And Display Manufacturing

Hummink’s HPCaP technology enables sub-micron printing of metals and functional materials, and can repair defects in real time during chip and display manufacturing helping prevent costly production failures in microelectronics.

The company operates teams in the US, Taiwan, Japan and South Korea, and plans to double its workforce by 2026 while targeting a revenue doubling this year, driven by growing demand for its printing modules and conductive inks.

The €15M round included participation from existing investors Elaia Partners, Sensinnovat, Beeyond, the French Tech Seed fund managed by Bpifrance under France 2030, and the European Innovation Council Fund.

The new capital will support the development of Hummink’s industrial printing module and accelerate its integration into semiconductor and display production lines globally.

Nuno Carvalho, Investment Director at KBC Focus Fund, says, “Hummink stands out as an exceptional deeptech company that bridges academic excellence with industrial relevance. Their HPCaP technology is not only a breakthrough in nanofabrication it’s a game-changer for defect repair in OLED and semiconductor manufacturing, where sub-5 micron precision is critical and unmet.”

“We’re proud to support Hummink’s journey from lab to fab, and believe their scalable business model and strong team position them to become a key enabler of next-generation electronics manufacturing.”

Founded in 2020 as a spin-off from École Normale Supérieure – PSL and the CNRS, Hummink was created by materials scientist Amin M’Barki and hardware startup operator Pascal Boncenne. The team developed a nano-scale printing method that deposits material through an ultra-fine tip with precise flow control similar to a microscopic fountain pen.

This enables circuit creation and repair at dimensions beyond the reach of conventional manufacturing tools, opening new possibilities in semiconductor packaging, memory technologies and display production.

While electronics production still depends heavily on lithography the process often introduces defects that lower yields and increase waste. Hummink addresses these challenges by offering tools that detect faults and rewrite circuit paths at the micronic scale, improving usable output, reducing scrap rates and lowering environmental impact.

The company’s first industrial application targets OLED display manufacturing for smartphones and laptops where a significant percentage of panels is discarded due to defects. Hummink’s technology can repair many of these issues and return panels to production.

Hummink generates revenue through its NAZCA system, a first-generation high-precision printing machine designed for R&D labs, enabling sub-micron fabrication and repair. The company also develops conductive inks tailored for its platform.

Co-founder Amin M’Barki says, “Our mission is to bring precision where it has never been possible before. Microelectronics is at the heart of the AI revolution, and every micron matters.” “With HPCaP, we give manufacturers a practical way to improve yields, cut waste, and make advanced technologies more sustainable,” adds co-founder Pascal Boncenne.

Hummink’s NAZCA system is now being used in laboratories and research centers across Europe, Asia, and the United States. At Duke University, researchers recently employed the platform to produce fully recyclable, sub-micrometer printed electronics featured in Nature Electronics.

The company is also undergoing qualification with major display manufacturers in Asia, where large volumes of panels are discarded due to fabrication defects. Early testing shows that NAZCA can recover part of this lost output, with initial data suggesting potential yield improvements of around 10%.

As chips and displays become more complex, production lines need tools capable of operating at matching levels of precision. Hummink aims to integrate its sub-micron printing technology directly into manufacturing environments worldwide, enabling circuit formation and repair during production.

Francois Charbonnier, Investment Director at Bpifrance, says, “Yield improvement is becoming one of the most critical levers in advanced manufacturing. Hummink’s combination of precision, speed, and scalability makes it a foundational technology for the next generation of microelectronics.”

“Breakthroughs like Hummink’s redefine what’s possible in manufacturing,” adds Flora Coppolani, Partner at CapHorn. “Their ink-based nanoprinting platform unlocks a new paradigm of control and scalability, bridging the gap between research and industrial scale, a true cornerstone for the next wave of deeptech innovation.”
