Defect engineering is the deliberate introduction, removal, or manipulation of structural imperfections in nanomaterials to tailor their properties for specific applications. Unlike the traditional ...

Scientists used Lorentz transmission electron microscopy (LTEM) to visualize topological defects. They were able to do so by passing electrons and observing their deflections through a thin magnetic ...

Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the ...

Researchers created a high-resolution 3D ultrasonic imaging system for concrete that uses broadband ultrasonic signals to automatically adapt to different types of concrete structures. WASHINGTON, Jan ...

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 ...

The third type of magnetism could prove the most useful of all—if researchers can identify the materials that exhibit it.
