If you are a chip foundry dealing with high scrap rates during 3D chip stacking, this project developed the SQI imager that detects defects with sub-100 nm resolution. This allows you to find failures faster and reduce waste in production.
High-Resolution Quantum Microscopy for Reducing Semiconductor Chip Defects and Scrap Rates
Imagine using a tiny, super-sensitive diamond needle to 'feel' the invisible magnetic leaks in a computer chip. This tool acts like a high-powered magnifying glass that finds microscopic cracks or errors without breaking the chip. It's like finding a needle in a haystack, but the needle is a magnetic glitch and the haystack is a piece of silicon.
What needed solving
Current semiconductor quality control methods like thermal imaging are insufficient for modern miniaturized chips. This leads to higher scrap rates and difficulty in detecting defects in 3D chip stacking and AI accelerators.
What was built
The Super-Resolution Quantum Imager (SQI), a non-destructive microscopy tool using diamond NV centers to detect magnetic field alterations.
Who needs this
Who can put this to work
If you are a security firm dealing with Hardware-Trojans or side-channel attacks, this project developed a quantum sensing tool that detects magnetic field alterations. This enables the identification of malicious modifications at the hardware level.
If you are a manufacturer dealing with quality control for GaN power devices, this project developed a non-destructive testing system. It provides rapid measurement times of less than 1 minute to ensure device reliability.
Quick answers
What is the cost or pricing model for this technology?
Based on available project data, specific pricing or cost details are not provided; however, the company is transitioning from providing testing services to commercializing the SQI system.
Can this be scaled for industrial production lines?
Yes, the project aims for TRL9 industrial readiness, focusing on a field of view greater than 50 μm and measurement speeds under 1 minute to fit manufacturing workflows.
What is the IP or licensing status?
The project utilizes proprietary diamond production and software. Based on available project data, specific licensing terms are not listed, but the technology is being integrated into real-world manufacturing.
How long does a typical measurement take?
The system is designed for rapid measurement times in the range of minutes, specifically targeting less than 1 minute per scan.
How does this integrate with existing semiconductor testing?
It serves as a non-destructive alternative to thermal imaging or voltage measurements, specifically for failure analysis and quality control in post-processing.
Who built it
The project is led by a single German SME, QuantumDiamonds GmbH, which maintains a 100% industry ratio. This lean structure is supported by a high-profile advisory network including TSMC, ARM, Infineon, and Applied Materials, indicating a strong bridge between a small agile developer and the world's largest semiconductor enterprises.
