Devices for determining a state of magnetic field-generating article are provided. In various embodiments, a device comprises a single crystal diamond having a plurality of NC centers, the single crystal diamond configured to be disposed adjacent to a magnetic field-generating article, and configured to generate a fluorescent signal in response to being illuminated by a light source; a coherent light source configured to generate a light beam directed a the single crystal diamond; a microwave (MV) radiation source configured to irradiate the single crystal diamond with a MW signal; a magnetic field source configured to apply a bias magnetic field to the single crystal diamond; a photosensor configured to collect the fluorescent signal generated by the single crystal diamond; and a computing node operatively coupled to each of the coherent light source, the ME radiation source, the magnetic field source, and the photosensor.
Quantum Diamond Microscope: A Leap Forward in Microelectronic Security
Quantum Diamond Microscope (QDM) is a semiconductor quality assurance tool capable of remarkable imaging not currently available in the microelectronics market. Better yet, QDM is not nearly as exotic or expensive as the name might suggest, with most parts available as commercial off-the-shelf items.
Why We Need It
Integrated circuits and other microelectronics components are at the core of devices that people, industry, and governments use each day. Our use of these products is only predicted to increase in complexity and expand in scale. QDM provides an industry-first, wide-field magnetic mapping of these components to analyze them for potential faults and to ensure their security. Furthermore, non-destructive analysis modes provide through-sample imaging allowing for post-manufacture inspection of a system—a vital attribute for cost and time-conscious manufacturing.
How it Works
Key to its operation, the QDM utilizes nitrogen-vacancy (NV) centers within diamond to capture wide-field images of a sample’s magnetic vector field, providing a non-destructive means to image a large variety of samples.
Real-World Applications
- Imaging of microelectronic components
- Fault analysis
- Research activities within biology, geology, and material science
- Advantageous in professional, college, and high school settings
Recognition
QDM is the winner of the 2023 ACT-IAC Innovation Champion Award at the Emerging Technology & Innovation Conference.
