The display and semiconductor industries are facing an escalating challenge driven by the rapid miniaturization and complexity of next-generation electronics. Critical components in emerging technologies, such as MicroLEDs, OLEDoS, and advanced semiconductor packaging, demand ultra-precise manufacturing capabilities. However, conventional manufacturing lines suffer from significant yield losses. In display manufacturing alone, defect rates range from 30% for OLED/LCD screens up to 70% for MicroLEDs, resulting in an estimated $16 billion lost globally every year. Standard open-defect repair solutions, such as Laser Chemical Vapor Deposition (CVD) or conventional Inkjet printing, lack the sub-micron resolution, speed, or versatility needed to repair microscopic open defects (less than 5 µm) without risking further damage. This high rate of discarded production generates vast amounts of electronic waste, consumes massive volumes of raw materials and energy, and undermines European technological sovereignty in critical supply chains.
The main objective of the BIRD project is to transition Hummink’s breakthrough High Precision Capillary Printing (HPCaP) technology from a standalone prototyping tool (NAZCA) into a commercial-grade, fully integrated industrial repair module. By leveraging capillary forces via oscillating micropens, HPCaP achieves sub-micron resolution (100 nm to 50 µm) with unmatched precision, depositing functional inks on any substrate without satellite droplets or thermal damage. The project pathway to impact focuses on seamlessly integrating these printhead modules into existing High-Volume Manufacturing (HVM) production lines through OEM system integrators. By providing a direct, high-throughput repair mechanism for missing interconnections and redistribution layers, BIRD directly improves yield rates, drastically reduces material scrap, and lowers energy consumption across the display, semiconductor, and sensor manufacturing sectors.
The project's expected impacts are significant in scale, strategic alignment, and economic value. Economically, the HPCaP module is projected to save display manufacturers over €275 million annually by recovering high-value panels that would otherwise be scrapped. Environmentally, by enabling the repair of millions of square meters of displays each year, the project reduces hazardous e-waste and raw material extraction, directly supporting the European Green Deal, the Ecodesign Directive, and the EU’s "Fit for 55" climate targets. Strategically, the technology strengthens European sovereignty in advanced microelectronics manufacturing, aligning with the objectives of the European Chips Act to bolster resilient, high-yield regional production. Addressing a Serviceable Obtainable Market (SOM) estimated at €91 million by 2028, BIRD establishes a European deep-tech innovation as the global standard for high-precision electronics defect repair.
