Bavarian Deputy Minister-President and German Federal Ministry for Economic Affairs (BMWE) visit as QuantumDiamonds opens first section of its new Munich production facility

Munich, Germany, July 23, 2026 - QuantumDiamonds GmbH (QD), a novel manufacturer of semiconductor inspection systems based on quantum sensing, has brought online the first operational section of its new facility in Munich, the site set to become the world's first production facility for semiconductor inspection based on quantum sensing. The section was completed on a fast track time line within four months, under the framework of the European Chips Act, achieving a first concrete milestone in the build-out of QD's production capacity.

To mark the occasion, QuantumDiamonds hosted Hubert Aiwanger, Bavarian Deputy Minister-President and State Minister for Economic Affairs, Regional Development and Energy, and Dr. Irina Kerner of the German Federal Ministry for Economic Affairs and Energy (BMWE). The delegation toured the newly completed section, saw QD's commercial system in operation, received a live demonstration, and previewed QD's latest development work toward InLine full-wafer mapping.

The fast track section houses the initial part of QD's laboratory environment. Completing it ahead of schedule allows QuantumDiamonds to begin ramping capacity for its Quantum Diamond Microscope (QDm.1) and to move manufacturing closer to the volumes its semiconductor customers require. The facility is being built to become the first dedicated production site worldwide for semiconductor inspection systems based on quantum sensing, giving Europe a commercial and technological lead in a cutting-edge inspection capability.

"Opening the first section of our Munich facility turns our roadmap into something you can walk through," said Kevin Berghoff, CEO and co-founder of QuantumDiamonds. "This is where we scale from delivering individual systems to building a production line for semiconductor inspection. We are grateful to the federal government and the Free State of Bavaria for backing this path, and proud to show a product that is already in the field with a technology that is validated through real customer measurements everyday."

During the tour, the delegation saw the QDm.1 in operation. The system leverages atomic-scale defects in synthetic diamond, so-called nitrogen-vacancy centers, to detect electrical currents with extreme precision: effectively a microscope that can see electricity flowing through chips. It delivers non-destructive, high-resolution 3D imaging of current pathways inside advanced 2.5D and 3D chip architectures, pinpointing the precise location and depth of defects within minutes, where conventional tools require lengthy, destructive, layer-by-layer sample debugging.

QuantumDiamonds also gave its guests a preview of its most advanced development work, the move toward InLine full-wafer mapping. This next step is aimed at bringing QD's imaging capability directly into semiconductor production and test flows at wafer scale, a capability of strategic importance for European chip manufacturing.

"Showing our path toward InLine full-wafer mapping is showing where inspection is going," said Dr. Fleming Bruckmaier, co-founder and CTO of QuantumDiamonds. "Bringing this capability to full-wafer scale inside the production flow is one of the hardest and most valuable problems in the field, and this facility gives us the ground to solve it."

In the course of the visit, the German federal government and the Free State of Bavaria also officially handed over the funding decision for QuantumDiamonds under the European Chips Act, jointly co-financing the company's production ramp-up.

"With QuantumDiamonds' project we are supporting a future technology with international reach," said Hubert Aiwanger, Bavarian Deputy Minister-President and State Minister for Economic Affairs, Regional Development and Energy. "The company combines Bavarian top-level research with industrial implementation and strengthens our technological sovereignty in one of the most important key technologies of our time. Anyone who wants to be independent in semiconductors must also master the technologies used to inspect and qualify chips. This is exactly where QuantumDiamonds comes in."

About QuantumDiamonds

QuantumDiamonds GmbH, headquartered in Munich, Germany, develops and manufactures semiconductor inspection systems based on quantum sensing. Spun out of the Technical University of Munich in 2022, the company uses nitrogen-vacancy centers in diamond to map electrical current with micrometer precision inside advanced 2.5D and 3D chip architectures. Nine of the world's ten largest semiconductor manufacturers are engaged with QuantumDiamonds, with systems deployed across Europe, the United States, and Asia. The company is investing €152 million to build the world's first production facility for quantum sensing-based semiconductor inspection tools, supported under the European Chips Act.
