QuantumDiamonds expands to Asia, starting with new operation in Taiwan
QuantumDiamonds GmbH of Munich, Germany, which is developing and manufacturing semiconductor testing systems based on diamond quantum sensing technology, has appointed Peter Lemmens as managing director Asia, signalling its commitment to establishing a lasting, on-the-ground presence in the region.
The appointment coincides with QuantumDiamonds’ expansion into Asia by establishing a new operation in Taiwan, which will serve as the firm’s regional hub as it scales commercial and technical activities across the semiconductor ecosystem in the months ahead.
Founded in 2022, in November 2025 QuantumDiamonds announced a €152m investment in a next-generation quantum-based chip inspection facility. The next move focuses on building an operational base for QuantumDiamonds in Asia, beginning with Taiwan.
Lemmens has more than 25 years of executive leadership in the semiconductor and electronics industry, including over 15 years based in Taiwan.
He is said to have a proven record of building and scaling organizations that serve the world’s most advanced chipmakers. Most recently, he was general manager Taiwan at IMS Nanofabrication, which provides multi-beam electron mask writing systems for leading-edge technology nodes, where he built the Taiwan operation from the ground up into a team of more than 100 staff, with full P&L responsibility and direct collaboration with TSMC.
Before IMS, he spent a decade as generalvmanager Taiwan for nanoelectronics research center imec of Leuven, Belgium. There, he founded imec's first technology center outside Europe and grew it into a 75-person, multi-country organization spanning R&D, business development, and account management. Lemmens began his career with a 12-year stint at global electronics firm Phillips.
His network spans the highest levels of the semiconductor ecosystems in Taiwan, Japan and Korea, including TSMC, Samsung, ASE, UMC and leading global IDMs, positioning him to drive adoption of QuantumDiamonds’ technology at scale, the firm reckons.
“The semiconductor industry is navigating an inflection point,” says QuantumDiamonds’CEO Kevin Berghoff. “As device architectures grow more complex through 3D stacking, advanced packaging, and backside power delivery, the demand for non-destructive, high-resolution metrology solutions has never been greater,” he adds. “Peter has spent his career at the center of this ecosystem. His operational depth, industry credibility and track record of building profitable businesses from the ground up make him exactly the right leader to accelerate our growth across Asia.”
QuantumDiamonds has commercialized the world’s first integrated quantum sensing system for semiconductor failure analysis. Based on patented Quantum Diamonds Microscopy (QDM) technology, the platform delivers non-destructive, high-resolution 3D imaging of electrical current pathways in complex chip architectures, including 2.5D and 3D packages, backside power networks, and wide-bandgap materials such as gallium nitride (GaN) and silicon carbide (SiC).
Where conventional optical methods require destructive layer-by-layer analysis, QDM can localize faults in minutes, dramatically compressing failure analysis cycles and improving manufacturing yield.
“Open faults are the number-one yield killer in advanced semiconductor manufacturing, and the industry has lacked an effective, non-destructive solution — until now,” says Lemmens. “QuantumDiamonds has built something genuinely transformative. The ability to visualize electrical activity in three dimensions, without destroying the sample, is a step change in what failure analysis engineers can do. I look forward to working closely with customers and partners across Asia to bring this capability into their production environments.”
QuantumDiamonds says that nine of the world’s top ten semiconductor manufacturers are already engaged with it, with active customer interest across Taiwan, Japan and Korea. In March it announced its first deployments across commercial environments in the USA and Taiwan.
