Quantum Diamonds, a Munich‑based startup, closed a €91m round combining €15m of equity and €76m of non‑dilutive financing. The lead equity investor is World Fund, joined by Bayern Kapital, IQ Capital, Earlybird, First Momentum, Unternehmer TUM Funding for Innovators, Creator Fund and Onsight Ventures. German government agencies provide the non‑dilutive tranche.

The firm supplies quantum‑sensing microscopes that detect hidden defects in advanced chip packaging. The technology promises a single percentage‑point yield lift, translating into millions of dollars in weekly savings for high‑volume manufacturers. Nine of the world’s top ten semiconductor makers deploy the system in the US and Taiwan, while Quantum Diamonds ramps production in Munich.

With 70 employees, the company plans to double its engineering team within a year, positioning itself as a potential rival to European equipment leaders. The funding fuels both research and the construction of a new production facility.

Investors view the deal as a catalyst for Europe’s semiconductor equipment sector. The yield gains and cost reductions could shift supply‑chain dynamics, reduce reliance on foreign tools, and create a new competitive edge for chipmakers that adopt quantum‑based inspection.
