QuantumDiamonds closes €91M (€15M equity + €76M grants) for quantum chip-inspection tech
Munich-based QuantumDiamonds, a spinout from Technical University of Munich making quantum-based semiconductor inspection tools, closed €15 million in equity funding led by World Fund, along with Bayern Kapital, IQ Capital, Earlybird, First Momentum, and others. The round is backed by an additional €76 million in non-dilutive funding from Germany's Federal Ministry for Economic Affairs and Energy and the Free State of Bavaria, totaling a €91 million raise.
The startup's microscope for electric currents detects hidden defects in 3D chip architectures without destroying samples—a critical bottleneck in yield optimization. A single percentage-point yield improvement can be worth millions of dollars per week for high-volume production. QuantumDiamonds currently deploys systems with nine of the top 10 chipmakers globally, with active installations in the US and Taiwan, and is scaling production in Munich.
The company employs 70 people and plans to more than double its engineering team over the next 12 months. For architects designing chip production lines or evaluating yield-improvement capital, this signals the emergence of quantum sensing as table-stakes infrastructure; World Fund's comparison to ASML's dominance in lithography underscores the long-term positioning. Non-destructive, AI-compatible inspection at scale becomes a differentiator in sub-3nm manufacturing.
