Invisix Closes €20M to Enable Advanced Chip Manufacturing

The big picture: Invisix, an Eindhoven-based semiconductor metrology company, has closed an oversubscribed €20 million Seed round. The funding, supported by Hitachi Ventures, Transition Ventures, imec.xpand, Doosan Investment Co., and a tier-1 semiconductor manufacturer, will accelerate the development of its next-generation measurement tools for advanced chip manufacturing.

Why it matters:

• Visibility Gap: Modern chip manufacturing involves building increasingly complex 3D structures at nanoscale, which current optical metrology tools cannot adequately inspect without destruction.
• Yield & Cost Impact: The inability to precisely measure internal chip structures leads to slower production, higher costs, and reliance on destructive testing, hindering yield improvements crucial for billions in revenue.
• AI Foundation: Advanced logic and memory devices, critical for high-performance computing and AI, depend on precise manufacturing, making new metrology solutions essential for industry progress.

How it works:

• Soft X-ray Metrology: Invisix employs short-wavelength, broadband soft x-ray scatterometry to non-destructively reconstruct detailed 3D internal structures of next-generation semiconductor devices.
• High Harmonic Generation (HHG): The technology leverages HHG, a process recognized by the 2023 Nobel Prize in Physics, to excite noble-gas atoms, emitting soft x-rays at multiple wavelengths for a richer 3D signal.
• Integrated System: Invisix combines HHG with proprietary reconstruction algorithms and machine learning to achieve high-throughput, non-destructive measurement, scaling to the demands of high-volume manufacturing.

The catch: While Invisix benefits from a decade of incubation and technology licensing from ASML, a major semiconductor equipment manufacturer, the market for advanced metrology is highly competitive and capital-intensive. Rapid customer adoption and scaling to high-volume manufacturing environments will be critical to overcome established incumbents and justify the significant investment in a specialized hardware solution.
