Eindhoven-based semiconductor metrology company Invisix, developing next-generation measurement tools for advanced chip manufacturing, has raised an oversubscribed €20 million seed round from Hitachi Ventures, Transition Ventures, imec.xpand, Doosan Investment Co., and a tier-1 semiconductor manufacturer.
- Founded in 2025 by Christina Porter and Sietse van der Post, Invisix builds soft x-ray-based systems that measure the internal structures of advanced chips during production.
- The company targets a key bottleneck in semiconductor manufacturing, where traditional optical tools can no longer resolve the increasingly small and three-dimensional features inside modern devices.
- The technology is based on High Harmonic Generation (HHG), where short laser pulses excite noble-gas atoms to produce soft x-rays at multiple wavelengths. These x-rays interact with a wafer and generate signals that carry information about buried structures.
- Invisix processes this data using reconstruction algorithms and machine learning to create detailed 3D maps of chip features, enabling non-destructive inspection during fabrication.
- The system is designed for integration into high-volume manufacturing lines, supporting process control and yield monitoring as chip architectures become more complex.
Details of the deal
- The new funding will support the company’s shift toward commercialization, including building its first production-ready system, expanding its technical team, and scaling customer testing at its Eindhoven cleanroom while continuing development for industrial deployment.
"It's exciting to see world-class talent come out of ASML and build companies of their own. Invisix is one of Europe's most promising semiconductor companies: they unlock a major bottleneck for manufacturing advanced chips that power AI training and inference. The technology is de-risked, the market is moving fast, and we're thrilled to back them as they scale," claims Clara Ricard, Partner at Transition Ventures.
