The perpetual march toward smaller features, coupled with growing demand for better reliability over longer chip lifetimes, has elevated inspection from a relatively obscure but necessary technology ...

Electron-beam inspection is proving to be indispensable for finding critical defects at sub-5nm dimensions. The challenge now is how to speed up the process to make it economically palatable to fabs.

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Over the last 20 years, the proliferation of research utilizing scanning electron microscopy (SEM) has driven the performance of systems towards higher resolution at lower voltages. This enthusiasm is ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

Scanning electron microscopy (SEM) has been an important tool for forensic science since the 1970s, and it continues to find forensic applications today. The technique – capable of 100,000x ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...
