Invisix Raises €20M for Advanced Chip Metrology

Invisix, a deeptech firm focused on revolutionizing semiconductor inspection, has successfully closed a substantial €20 million seed funding round. This significant capital infusion is earmarked to accelerate the development and commercialization of its novel metrology solutions, crucial for the next generation of advanced chip manufacturing. The round saw robust participation from prominent investors including Hitachi Ventures, Transition Ventures, imec.xpand, and Doosan Investment Co., alongside a strategic investment from a leading semiconductor manufacturer.

The escalating complexity and miniaturization of semiconductor components present a formidable challenge for current metrology techniques. As chip architectures become more intricate, particularly with the rise of 3D stacking and advanced logic nodes, traditional optical methods struggle to accurately measure critical internal features. This limitation directly impacts manufacturing yields and production timelines, especially for high-performance computing and AI-driven applications that demand unparalleled precision and speed in verification processes.

Leveraging groundbreaking physics, Invisix's technology is rooted in High Harmonic Generation (HHG), a phenomenon recognized with the 2023 Nobel Prize in Physics. This advanced approach utilizes precisely tuned, short-pulsed lasers to generate soft X-rays. Unlike conventional single-wavelength systems, HHG produces a richer, multi-wavelength X-ray spectrum, enabling a more detailed three-dimensional understanding of subsurface structures within semiconductor wafers without causing damage.

The company, founded by seasoned ASML veterans Christina Porter (CEO) and Sietse van der Post, has developed a proprietary platform that combines HHG with sophisticated reconstruction algorithms and machine learning. This synergy allows for the creation of high-resolution 3D images of internal chip elements, a capability that is becoming indispensable for ensuring the integrity and performance of cutting-edge microelectronics. Crucially, the system's architecture is engineered for the high throughput demands of mass production environments.

Invisix's innovative approach mirrors the fundamental principle that drove advancements in lithography: as feature sizes shrink, so too must the wavelength used for measurement. By employing soft X-rays, Invisix aims to provide unprecedented visibility into nanoscale features that are increasingly obscured from optical inspection. This capability is vital for manufacturers striving to maintain quality control and accelerate innovation in a fiercely competitive global semiconductor market, which is projected to reach over $1 trillion by 2030.

The company has already garnered validation through collaborative projects with industry leaders such as Intel and imec, underscoring the market's readiness for its disruptive technology. With its new cleanroom facility in Eindhoven operational, Invisix is now focused on deploying its initial commercial systems and supporting customer evaluations. The newly secured funding will be instrumental in expanding the engineering team, advancing product development, and scaling up customer engagement to meet the growing demand for next-generation metrology solutions.
