QuantumDiamonds Raises €91M for Chip Inspection Tech

QuantumDiamonds, a Munich-based chip-inspection startup, has raised €91 million in combined equity and non-dilutive funding to scale production of its quantum-sensing inspection systems for global semiconductor fabs.

The Deal

The round consists of €15 million in equity funding and €76 million in non-dilutive funding, the latter forming part of a $178 million investment plan backed by Germany's federal economy ministry and the state of Bavaria, with EU approval. The equity portion was led by World Fund.

QuantumDiamonds is a spinout from the Technical University of Munich (TUM), founded by CEO Kevin Berghoff and CTO Dr. Fleming Bruckmaier. The company currently employs 70 people, mostly based in Munich.

The Technology

QuantumDiamonds applies a novel quantum-sensing approach to inspecting semiconductor chips, compressing a defect-detection process that traditionally takes weeks into a two-minute inspection. The company says it already works with nine of the world's top 10 semiconductor manufacturers, though their identities are not disclosed.

The startup has live deployments in the US and Taiwan, including an installation at Eurofins EAG Laboratories in Sunnyvale, California. In 2026, QuantumDiamonds opened a regional hub in Taiwan and completed its first commercial deployments in both Taiwan and the US. Taiwan-based foundries and Korea's memory makers are cited as potential future customers.

Pricing and Market Position

QuantumDiamonds' lab tools cost in the single-digit millions, while its planned high-throughput system could cost between $10 million and $15 million. For comparison, ASML's machines cost approximately $400 million. World Fund's Daria Saharova pointed to a $104 billion semiconductor equipment market as the broader opportunity the company is targeting.

What's Next

Over the next 12 months, QuantumDiamonds plans to expand its engineering team and build a new production facility in Munich. Sources differ on the exact scale of this hiring push: Sifted reports the company intends to "more than double" its engineering team, while TechCrunch states the plan is simply to "double" it. No timeline has been given for when the new Munich facility will become operational.

Notably, CEO Kevin Berghoff has floated the possibility of an eventual acquisition by a larger player, saying, "ASML also wants to do more [when it comes to] inspection, so they are a typical company that might buy us at some point."

Risks to Watch

Grant dependency: Reliance on a small number of large non-dilutive government grants could expose the company to regulatory or policy shifts.
Hiring strain: Rapidly scaling engineering headcount within 12 months may strain hiring and integration processes.
Pricing ceiling: The $10-15 million price tag for its high-throughput system could limit adoption compared to cheaper lab-tool alternatives.
Acquisition risk: Potential interest from larger players like ASML could affect the company's long-term independence.

What's Missing

The report does not disclose QuantumDiamonds' post-money valuation, specific revenue or customer contract figures, details of the European Commission's approval process for the non-dilutive funding, or the identities of the top-10 semiconductor manufacturers it works with.

Why Founders Should Care

This round offers a data point for hardware and deep-tech founders navigating the tension between dilution and growth capital. The mix of equity and government-backed non-dilutive funding suggests it's plausible for capital-intensive startups to reduce dilution while scaling, particularly in strategically important sectors like semiconductors.

The speed of QuantumDiamonds' commercial traction — moving from lab tool to multi-region deployments, including at a major manufacturer, within a short window — may indicate that hardware startups offering clear efficiency gains (like cutting inspection time from weeks to minutes) can attract enterprise customers faster than typical hardware adoption cycles suggest.

The EU and German government's willingness to back a private semiconductor-tooling startup with tens of millions in non-dilutive funding likely signals growing public-sector appetite to support supply chain innovation in critical technology sectors — a trend founders in adjacent hardware or deep-tech markets may want to monitor.

Finally, the CEO's own comments about potential acquisition interest from ASML hint that strategic partnerships or acquisition exits could become increasingly relevant considerations for founders building tools that established equipment giants might eventually want to own rather than compete against.
