Europe uses about a fifth of the world's chips, but makes only a tenth of them. A three-year-old Munich startup thinks it can help close that gap, and Brussels has just backed the bet.

QuantumDiamonds is a spin-out of the Technical University of Munich. It has raised €91M to scale a new way of finding faults inside advanced chips. The round has two parts. One is €15M of equity, led by climate-tech fund World Fund.

The other is €76M of state aid, approved under the European Chips Act.

The state money is the real headline. QuantumDiamonds is set to become the first startup ever to win manufacturing funding under the Chips Act. Until now, that pot has gone to giants such as GlobalFoundries and Carl Zeiss.

A microscope that sees electricity

Chipmakers have a yield problem. As they stack transistors into ever denser 3D designs, defects get harder to find. A single buried flaw can ruin a whole batch. Standard optical and X-ray tools often cannot see past the top layers.

QuantumDiamonds takes a different route. It exploits tiny atomic flaws in lab-grown diamonds to sense magnetic fields with extreme precision. That effectively turns a diamond into a microscope that can watch electricity flow through a chip.

Its first product, the QDm.1, images those currents in 3D at the nanoscale. Crucially, it does so without damaging the chip. It can pinpoint the exact depth and position of a defect buried inside a stacked package.

One US chip designer had spent six weeks hunting a fault. The tool found it in under a minute.

Why yield is worth billions

The economics are stark. On a high-volume product, lifting yield by a single percentage point can be worth millions of dollars a week. Anything that spots defects faster, and earlier, goes straight to the bottom line.

That is why money is chasing this corner of the industry. The market for chip inspection should reach $10.9bn in 2026. Global Market Insights expects it to roughly double by 2035. QuantumDiamonds says it already works with nine of the world's ten largest chipmakers.

Europe's next ASML?

The pitch to investors leans hard on sovereignty. “Europe uses around 20% of the world's semiconductors while producing only 10%, and that gap is exactly where our strategic power leaks away,” said Daria Saharova, managing partner at World Fund.

She went further, casting the startup as a future national champion. “QD can become Europe's next ASML,” she said, invoking the Dutch firm whose machines the whole chip industry depends on. It is a bold claim for a company with one product. But it captures the mood in Brussels.

The €76M grant comes from the German federal government and the Free State of Bavaria. Brussels cleared it on 23 June. It fits a wider European push: make more chips at home, and lean less on the US and Asia.

A crowded, consolidating field

QuantumDiamonds is not alone in the diamond-sensing niche. Its closest technical rival, the Swiss startup Qnami, was bought by Quantum Design in June, Tech Funding News reported. That deal folded Qnami's technology into a broader instruments group rather than scaling it alone.

The incumbents are far larger. KLA holds roughly 17.5% of the inspection market, with Applied Materials and Onto Innovation close behind. All three rely on light and electron beams, the very methods that struggle with buried defects. That is the gap QuantumDiamonds is trying to prise open.

From lab to fab

The company now has to turn trials into paid production contracts. It installed its first US system at a lab in Sunnyvale, California, in April. Its first Asian system followed in Hsinchu, Taiwan, the heart of the world's chip cluster.

The new cash will fund a €152M plant in eastern Munich. The company bills it as the first facility of its kind for advanced chip-testing systems. The first section is due to open later this year.

QuantumDiamonds employs 70 people and plans to more than double its engineering team within a year.

Why it matters

Europe keeps talking about technological sovereignty, then watching its best deep-tech firms get bought or built elsewhere. The Qnami sale is a fresh example. The Chips Act grant is a bet that a homegrown startup can scale into a strategic supplier instead. It serves a market the whole AI boom quietly depends on.

The firm's fate will turn on one thing: how fast those nine trials become paid contracts.
