Researchers have designed a robust image-based anomaly detection (AD) framework with illumination enhancement and noise suppression features that can enhance the detection of subtle defects in ...

Defect states refer to electronic energy levels that arise from imperfections or irregularities in the crystal structure of materials, particularly in semiconductors and insulators. These ...

This diagram depicts how metals with a smoother surface are less prone to the accumulation of hydrogen-induced defects, namely dislocations and vacancy clusters. As the world strives to achieve carbon ...

Figure 1. Ultrasonic testing using pulse echo and through-transmission methods. Pulse echo (left and center) uses a transducer that sends and receives ultrasound energy, producing both A- and B-scan ...

Variation is becoming a bigger problem in multi-die assemblies with TSVs and hybrid bonding. Multi-modal approaches are required to test these devices. AI plays a role in improving defect capture rate ...

Reducing defects on the wafer edge, bevel, and backside is becoming essential as the complexity of developing leading-edge chips continue to increase, and where a single flaw can have costly ...

Researchers used AI-guided electron microscopy to map atomic-level point defects in 3D within ultrathin MXene layers, ...
