€91 million will fund QuantumDiamonds’ quantum diamond microscopy business and the first phase of a planned €152 million production site in eastern Munich, due to start operating later in 2026.
€76 million of the round comes from EU Chips Act grants via the German federal government and Bavaria, with the remaining €15 million in private equity led by World Fund.
QuantumDiamonds uses diamond NV centers to map electrical current inside chip packages with micrometer precision without opening them, targeting increasingly complex 2.5D and 3D semiconductor designs.
Nine of the world’s 10 largest chipmakers have already completed proof-of-concept projects with the company, which says it has deployments in Europe and installations in the US and Taiwan this year.
The raise underscores how diamond NV technology is commercializing fastest in sensing rather than computing, with semiconductor inspection emerging as one of the clearest near-term markets.
In July 2026, QuantumDiamonds secured €91 million in funding, combining a €15 million equity round led by World Fund and Bayern Kapital with €76 million in non-dilutive grants from the European Chips Act. This major investment is dedicated to strategic initiatives, including accelerating the delivery of advanced lab systems to top chipmakers and developing wafer-level capabilities for high-throughput semiconductor inspection. By leveraging this funding, QuantumDiamonds aims to strengthen its position in the industry, support the expansion of its Munich facility, and play a key role in advancing Europe’s semiconductor technology and independence.
