Paris-based startup Hummink has raised €15 million to accelerate deployment of its ultra-precise printing technology, designed to resolve microscopic defects in advanced chips and displays. The round was co-led by KBC Focus Fund, Cap Horn, and Bpifrance, joined by historical investors Elaia Partners, Sensinnovat, and Beeyond.
The French Tech Seed fund participated on behalf of the French government as part of France 2030, while the European Innovation Council Fund also backed the round.
Capital will support development of Hummink’s industrial printing module and prepare its integration inside semiconductor and display factories. The team also plans to double its workforce by 2026, expand global presence across Asia and the U.S., and boost production of proprietary conductive inks utilized in ultra-fine electronic repairs.
Solving a €16B OLED waste problem
Even the best chip and display manufacturing processes generate flaws tinyer than a speck of dust. These are defects that can ruin entire production batches. In OLED display manufacturing alone, up to 30% of output is scrapped each year, equal to roughly €16 billion in losses and enough wasted material to cover thousands of football fields. Hummink aims to reduce this waste by enabling real-time repair at the sub-micron level.
Hummink was founded in 2020 by materials scientist Amin M’Barki and hardware startup operator Pascal Boncenne as a spin-off from École Normale Supérieure – PSL and the CNRS. The company’s mission is to allow manufacturers to build and correct electronic circuiattempt at the tiniest scales, increasing yields while lowering environmental impact.
Reduces chip waste through sub-micron repair
Traditional lithography continues to power most electronics manufacturing, yet even the most advanced processes still produce microscopic flaws that lead to costly yield losses and material waste.
Hummink addresses this challenge with its patented High-Precision Capillary Printing (HPCaP) technology, which operates like the world’s tinyest fountain pen, depositing metals and functional materials at extraordinary accuracy.
Acting as a surgical companion to lithography, it identifies and repairs defects directly at the sub-micron scale, supporting manufacturers increase output while significantly reducing scrap and environmental impact.
Hummink’s first system, the NAZCA demonstrator, is already deployed in leading research labs across Europe, Asia, and the United States. At Duke University, the technology enabled the creation of the first fully recyclable, sub-micrometre printed electronics, published in Nature Electronics.
What’s ahead?
As chips and displays become ever more complex, the ability to correct flaws at the same scale becomes a manufacturing necessity. By embedding its technology directly into fabrication lines, Hummink is at the heart of next-generation electronics production, boosting yields, reducing waste, and shaping a more efficient future for the global semiconductor and display indusattempt.
Nuno Carvalho, Investment Director at KBC Focus Fund commented: “Hummink stands out as an exceptional deeptech company that bridges academic excellence with industrial relevance. Their High-Precision Capillary Printing (HPCaP) technology is not only a breakthrough in nanofabrication—it’s a game-modifyr 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.”
“Yield improvement is becoming one of the most critical levers in advanced manufacturing,” stated Francois Charbonnier, Investment Director at Bpifrance. “Hummink’s combination of precision, speed, and scalability builds it a foundational technology for the next generation of microelectronics.”
“Breakthroughs like Hummink’s redefine what’s possible in manufacturing,” stated 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.”
