DiaSense

What DiaSense does

DiaSense is a Danish deep-tech startup developing a Quantum Diamond Magnetic Microscope for the semiconductor industry. The instrument uses nitrogen-vacancy (NV) center quantum sensing to detect magnetic fields generated by electrical current flow inside integrated circuits, enabling contactless, non-invasive failure analysis and inspection of buried structures at microscopic scale. The company positions the technology as a complement or alternative to traditional failure-analysis techniques such as e-beam, optical microscopy, and electrical probing, with claimed advantages in sensitivity, spatial resolution, and throughput for identifying subtle defects including interconnect issues and power distribution anomalies.

DiaSense's product is structured as one core instrument supporting two application modules: a Failure Analysis module aimed at chip R&D engineers for root-cause analysis with high sensitivity and throughput, and a Production Test & Monitoring module aimed at in-line fab use for contactless testing and fast fingerprinting of process variations. The go-to-market is direct enterprise sales to integrated circuit developers and manufacturers, with engagement expected to occur through technical demonstrations and pilot programs rather than channel partners.

The company is pre-commercial, has no disclosed revenue or named customers, and has raised approximately €1.9 million cumulatively from BioInnovation Institute (a Novo Nordisk Foundation Initiative) across two rounds. It operates with roughly five team members anchored by academic co-founders from DTU Physics and is supported by an ecosystem of Danish and European research and innovation funders including Danmark Frie Forskning, Innobooster, DTU Skylab, Danish Quantum Community, and Eureka. Revenue mechanics are expected to involve hardware sales and possibly service contracts, but pricing has not been publicly disclosed.

Core offering

DiaSense is developing a Quantum Diamond Magnetic Microscope that uses nitrogen-vacancy (NV) center quantum sensing to detect magnetic fields generated by current flow inside integrated circuits, enabling contactless chip failure analysis and production monitoring for semiconductor manufacturers. The instrument is positioned to provide high-sensitivity, high-throughput, non-invasive inspection of buried semiconductor structures, revealing failure mechanisms such as interconnect issues and power distribution anomalies that are invisible to traditional failure analysis techniques. The company operates as a pre-commercial startup and intends to deliver the technology as a sold instrument or contracted inspection service to chip developers.

Product overview

DiaSense offers a Quantum Diamond Magnetic Microscope technology platform for semiconductor chip failure analysis and production monitoring. The platform integrates three main components: the core Quantum Diamond Magnetic Microscope hardware, the Failure Analysis module for root-cause analysis with high throughput and sensitivity, and the Production Test & Monitoring module for in-line contactless testing and process variation detection. These integrated capabilities enable chip developers to accelerate diagnostics, reduce costly iterations, and increase yield and reliability.

Others

• Keysight Technologies: Sells electrical test & measurement instruments used for production test and RF/parametric characterization of semiconductors. Comparable as an enabling test-instrument vendor to the same chipmaker buyers, but focused on electrical rather than magnetic/quantum measurements.

Broad incumbents

• Bruker: Established scientific-instrument manufacturer with broad AFMs, nanoanalysis, and magnetic-imaging product lines (including diamond-NV products through partnerships). Comparable as an incumbent instrument supplier into semiconductor and research labs, even though its quantum-sensing line is not its core focus.
• Oxford Instruments (NanoAnalysis): Provides electron-microscopy and nanoanalysis tools used in semiconductor failure analysis and materials characterization. Comparable incumbent instruments supplier, though based on electron-beam rather than quantum sensing.
• Thermo Fisher Scientific (Failure Analysis): Sells SEM/FIB and dual-beam failure-analysis systems used by every major chipmaker. Comparable as the entrenched FA-instrument incumbent whose installed base defines the workflow DiaSense is targeting.
• Hitachi High-Tech: Major supplier of semiconductor metrology and failure-analysis tools (CD-SEM, FIB, defect review). Comparable incumbent that chipmakers rely on for FA and process monitoring workflows.
• Carl Zeiss SMT: Dominant supplier of electron-beam metrology, defect review, and failure-analysis tools to semiconductor fabs. Comparable as the incumbent FA/workflow supplier whose accounts DiaSense must displace, even though Zeiss's core technology is not quantum sensing.

Direct peers

• Qnami: Swiss startup that builds scanning NV-diamond (quantum diamond) microscopes for nanoscale magnetic imaging of materials and semiconductor structures. Closest direct competitor to DiaSense on the application of NV-center quantum sensing to chip and materials failure analysis.
• QZabre (Qnity): ETH Zurich spin-out (now operating as Qnity) that develops quantum diamond sensing tools, including NV-diamond magnetometers for materials and device characterization. Direct competitor in the quantum-diamond instrument category DiaSense addresses.
• NVision Imaging Technologies: German startup commercializing NV-diamond quantum imaging platforms for nanoscale magnetic imaging, with applications in semiconductors, spintronics, and materials research. Direct peer in quantum-diamond microscopy instrumentation.

Regional players

• Quantum Design: Distributor and manufacturer of physical-property measurement systems (PPMS, MPMS, AFM add-ons including diamond-NV options from partners) into research and industrial labs. Comparable channel/incumbent for quantum magnetic sensing instruments, though primarily serving the research market rather than chipmakers directly.
