3D Atomic-Scale Metrology of Strain Relaxation And Roughness in GAAFETs Via Electron Ptychography (Cornell, ASM, TSMC)


A new technical paper, "3D atomic-scale metrology of strain relaxation and roughness in Gate-All-Around transistors via electron ptychography," was published by researchers at Cornell University, ASM and TSMC. Abstract "Next-generation semiconductor devices are adopting three-dimensional (3D) architectures with feature sizes in the few-nanometer regime, creating a need for atomic-scale me... » read more

Advantages Of Measuring Surface Roughness With White Light Interferometry


The concept of measuring surface roughness originated nearly a century ago as a means to prevent uncertainty and disputes between manufacturers and buyers. Now, it has become a common identifier used throughout industry for validating manufacturing processes, confirming adherence to both internal and regulatory specifications, and guaranteeing quality and performance of end products. Subjective... » read more
