Paris: Deep-tech innovator Hummink has raised €15 million in a funding round co-led by KBC Focus Fund, Cap Horn, and Bpifrance, aimed at accelerating deployment of its patented micronic precision technology for semiconductor and next-generation display manufacturing.
The investment will support expansion of the company’s High-Precision Capillary Printing (HPCaP) platform, designed to detect and repair microscopic defects and enhance yields in advanced production lines.
Hummink Expands HPCaP Technology for Industrial Adoption
The newly raised capital will help the company integrate its High-Precision Capillary Printing (HPCaP) technology into large-scale manufacturing environments.
The platform enables printing of metals and advanced functional materials at record precision, allowing real-time repair of sub-micron flaws that typically cause substantial yield losses in the semiconductor and display sectors.

Founded in 2020 as a spin-off from École Normale Supérieure – PSL and CNRS by materials scientist Amin M’Barki and hardware startup operator Pascal Boncenne, Hummink developed a tool that functions like an ultra-miniaturized fountain pen.
The process writes circuitry at nanoscopic scale with precise material flow, facilitating fabrication and correction of components for semiconductor packaging, memory devices, and advanced displays.
Hummink Positioned to Reduce Waste and Improve Manufacturing Yields
While lithography remains the core method for electronics production, even the most advanced systems produce microscopic defects that lead to significant material waste.
Hummink’s HPCaP tools act as high-precision surgical instruments, complementing lithography by correcting such imperfections. This supports higher yields, reduced scrap, and improved sustainability across production lines.
“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,” said Amin M’Barki, Co-Founder and CEO of Hummink.
“With HPCaP, we give manufacturers a practical way to improve yields, cut waste, and make advanced technologies more sustainable,” added Co-Founder and COO Pascal Boncenne.
Hummink Targets OLED Display Defect Reduction
One of Hummink’s early industrial focus areas is next-generation OLED displays used in smartphones and laptops. Approximately 30% of global OLED production is discarded annually due to sub-micron defects, resulting in an estimated €16 billion in losses and thousands of football fields’ worth of wasted materials.
The company’s technology can address most of these imperfections, enabling manufacturers to recover yields otherwise written off.

Revenue currently comes from the NAZCA demonstrator, Hummink’s first-generation printing system for R&D laboratories. NAZCA enables researchers to access sub-micron fabrication and repair capabilities and is supported by tailor-made conductive inks developed in-house.
Hummink Gains Global Adoption in Research and Industry
NAZCA systems have been installed at major research centers in Europe, Asia, and the U.S., including Duke University, where researchers created the first fully recyclable, sub-micrometer printed electronics featured in Nature Electronics.
The company is now undergoing qualification with leading display manufacturers in Asia, with early results indicating potential yield improvements of around 10%.
With teams in the United States, Taiwan, Japan, and South Korea, Hummink plans to double its workforce by 2026 and expects to double annual revenue by the end of this year.
Funding Supports Industrial-Scale Module Development
The latest €15 million fundraising round includes participation from Elaia Partners, Sensinnovat, Beeyond, Bpifrance’s French Tech Seed fund under France 2030, and the European Innovation Council Fund.
The investment will accelerate development of Hummink’s industrial printing module and prepare its technology for integration directly inside semiconductor and display fabrication lines.
Investor confidence highlights the strategic value of Hummink’s precision printing platform in microelectronics manufacturing:
Nuno Carvalho, Investment Director, KBC Focus Fund: “Hummink’s HPCaP technology is a breakthrough in nanofabrication and a game-changer for defect repair in OLED and semiconductor manufacturing.”
Francois Charbonnier, Investment Director, Bpifrance: “Yield improvement is becoming one of the most critical levers in advanced manufacturing. Hummink offers a foundational technology for next-generation microelectronics.”
Flora Coppolani, Partner, CapHorn: “Breakthroughs like Hummink’s redefine what is possible. Their ink-based nanoprinting platform unlocks a new paradigm of control and scalability.”
