World Fund, IQ Capital among backers of €91m QuantumDiamonds round
Summary
Munich-based startup QuantumDiamonds, a spinout from the Technical University of Munich, has secured €91m in combined equity and non-dilutive funding as of July 9, 2026. The €15m equity round was led by World Fund, with participation from Bayern Kapital, IQ Capital, Earlybird, First Momentum, UnternehmerTUM Funding for Innovators, Creator Fund, and Onsight Ventures. An additional €76m in non-dilutive funding comes from the German Federal Ministry for Economic Affairs and Energy and the Free State of Bavaria. QuantumDiamonds develops advanced semiconductor inspection equipment, utilizing a quantum-based microscope for electric currents to non-destructively detect hidden defects in complex 3D chip architectures. This technology aims to significantly improve production yields and accelerate development cycles for next-generation packaging, addressing limitations of traditional tools that lower yields and increase costs. The company currently works with nine of the top 10 semiconductor manufacturers, has deployments in the US and Taiwan, and plans to more than double its 70-person engineering team within 12 months.
Key takeaway
For investors evaluating the semiconductor equipment market, QuantumDiamonds' €91m funding round and quantum-based inspection technology signal a critical shift. Your investment strategy should consider companies addressing the escalating yield challenges in complex 3D chip architectures, as a 1% yield improvement can generate millions weekly. This technology, already deployed with top manufacturers, suggests a significant market opportunity in a \$104bn equipment sector.
