Germany just secured a massive victory in the global semiconductor race. QuantumDiamonds GmbH is betting big on European innovation with a €150 million investment to build a state-of-the-art facility in Munich. This move bypasses American manufacturing hubs like Phoenix to keep critical quantum technology on home soil. It marks a pivotal moment for the European Chips Act and the future of checking computer chips.
A Major Win for European Tech
The decision to build in eastern Munich is not just about money. It represents a strategic shift in how the world handles semiconductor quality control. QuantumDiamonds is a spin-off from the Technical University of Munich. They decided to stay local after looking at options in the United States.
Kevin Berghoff, the CEO of QuantumDiamonds, explained the vision clearly.
“We are building the tools the chip industry needs to inspect what was previously invisible. We are doing it in Germany, with European IP and talent.”
The facility is designated as a “first-of-a-kind” project under the European Chips Act. This label is crucial. It opens the door for significant financial support from both the German federal government and the Bavarian state government.
The company received a “start-of-works” confirmation. This allows construction teams to break ground immediately without risking future funding eligibility. The site will house several critical operations under one roof.

Key Features of the New Facility:
- Sensor Production Lines: Manufacturing quantum-grade diamond substrates locally.
- Cleanroom Integration: specialized areas for assembling QDM inspection systems.
- Joint Development Labs: Spaces for collaboration with major semiconductor partners.
- Application Support: dedicated teams to help factories integrate these new tools.
Solving the Hidden Defect Problem
Modern electronics are getting smaller and more complex every year. Engineers are stacking chips on top of each other to make devices faster for AI and mobile phones. This creates a massive problem for quality control.
Traditional testing methods are failing. Techniques like X-ray imaging or lock-in thermography cannot see deep inside these complex 3D structures without destroying them. They miss tiny electrical failures that can ruin a device later.
QuantumDiamonds solves this with Quantum Diamond Microscopy (QDM). This technology uses synthetic diamonds to see the invisible.
It works by using nitrogen-vacancy (NV) centers inside a diamond. These are essentially atomic defects that are incredibly sensitive to magnetic fields. When a chip runs, it creates magnetic fields. The diamond maps these fields with extreme precision.
This allows engineers to see exactly how electricity flows through a chip. They can spot a broken connection or a short circuit buried deep inside a package-on-package device.
Why Traditional Methods Are Obsolete:
| Feature | X-Ray / CT Scans | Thermal Imaging | Quantum Diamond Microscopy |
|---|---|---|---|
| Depth Perception | Limited in dense stacks | Surface level only | Deep penetration mapping |
| Precision | Low resolution | Low resolution | Micrometer-level precision |
| Speed | Slow processing | Medium speed | Rapid, real-time imaging |
| Damage Risk | Radiation exposure | Heat stress | 100% Non-destructive |
Expanding Beyond German Borders
While the production hub is staying in Munich, the technology is going global. The demand for reliable chip testing is exploding alongside the artificial intelligence boom. Companies like Nvidia and AMD are pushing the limits of physics with their new processors.
They need a way to ensure these expensive chips actually work before they are sold.
QuantumDiamonds has already completed initial deployments across Europe. They are not stopping there. The company plans to install systems in the United States and Taiwan by the first quarter of 2026.
This global rollout targets the biggest players in the game. Taiwan is home to TSMC, the world’s largest chipmaker. The United States is currently pouring billions into its own domestic chip production. By placing units in these regions, QuantumDiamonds ensures its tech becomes the industry standard.
The focus is currently on three main sectors:
- Artificial Intelligence: Ensuring high-power GPUs do not fail under load.
- Mobile Electronics: Checking compact chips inside smartphones.
- Automotive: Verifying safety-critical sensors for modern cars.
The Science Behind the Diamond
The core technology relies on quantum physics but the concept is practical. You take a diamond and remove two carbon atoms. You replace one with a nitrogen atom and leave the other spot empty. This “vacancy” acts like a tiny compass.
It reacts to magnetic fields at a sub-atomic level.
When you place this diamond sensor over a computer chip, it acts like a camera. But instead of light, it takes a picture of the electricity. This provides a magnetic map of the current density.
Why this matters for the average person:
- Your phone battery could last longer because the chip is more efficient.
- Your car is safer because the sensors were tested more thoroughly.
- AI services become cheaper because fewer expensive chips are thrown away during manufacturing.
The technology is non-invasive. It does not require cutting the chip open. It does not require heating the chip up. It simply observes the magnetic fields naturally created by the electricity.
Securing the Supply Chain
The choice of Germany over Arizona highlights a growing trend in Europe. The continent is fighting hard to regain control of its industrial supply chain.
The European Chips Act was created for exactly this purpose. It aims to double Europe’s share of global chip production to 20% by 2030. Projects like the QuantumDiamonds facility are the building blocks of this ambition.
Munich offers a unique ecosystem. It has access to top-tier talent from universities. It has established supply chains for precision engineering. It has a government willing to invest in risky, high-reward technology.
The company noted that while Phoenix offered incentives, the total package in Bavaria was superior. This included the “ecosystem” factor. Being close to researchers and suppliers speeds up innovation.
This facility will secure the supply of the diamond sensors themselves. These are not jewelry-store diamonds. They are lab-grown to specific standards. Controlling this production is vital. If you rely on external suppliers for your core sensor, you are vulnerable to shortages. By making them in-house, QuantumDiamonds controls its own destiny.
This €150 million investment is a bold statement. It says that Europe intends to lead, not follow, in the next generation of semiconductor technology. The facility is moving forward, and the impact will be felt across the entire tech world soon.
