Munich-based semiconductor technology firm QuantumDiamonds has raised €91 million. The round includes €15 million in equity funding led by World Fund, along with €76 million in non-dilutive funding approved under the European Chips Act.
- Founded in 2022 by Kevin Berghoff and Fleming Bruckmaier, QuantumDiamonds develops tools that enable semiconductor manufacturers to detect hidden defects inside increasingly complex chips.
- The company’s technology uses synthetic diamond sensors containing nitrogen-vacancy centers to measure magnetic fields generated by electrical currents within semiconductor devices, allowing engineers to localize defects in three dimensions without damaging the chip.
- Its systems are designed to identify issues such as short circuits, open connections, and leakage currents in advanced semiconductor packages.
- QuantumDiamonds’ technology is already being deployed by semiconductor companies across Europe, the United States, and Taiwan, with the company working with nine of the world’s ten largest chip manufacturers.
- Its solutions include high-resolution chip-level defect analysis for research and failure analysis, as well as in-line wafer mapping technologies for future production monitoring.
Details of the deal
- The round also saw participation from Bayern Kapital and existing investors including IQ Capital, Earlybird Venture Capital, UnternehmerTUM Funding for Innovators, Creator Fund, Onsight Ventures, and First Momentum Ventures.
- The fresh capital will help QuantumDiamonds scale production, expand its engineering team, and accelerate the global deployment of its quantum sensing systems.
- The funding will also support the development of its €152 million production facility in Munich, which is being built to manufacture its sensors and inspection systems at industrial scale.
