Applications of SEM in Semiconductor Device Failure Analysis
Failure analysis (FA) is an essential methodology that engineers use in the development process of semiconductor devices, like the CPU found in your smartphone or laptop. It involves the application of multiple analytical tools to isolate the root cause of a particular failure mode to prevent it from happening in the future. Failure modes describe how a device is failing by not meeting a certain electrical, mechanical, or visual specification.
Decoding the Best Phenom SEM for Your Needs
Scanning electron microscopy (SEM) is an incredibly adaptable analytical method that generates high-resolution images by scanning a focused electron beam across the surface of a sample. Inside the SEM instrument, a range of detectors captures various signals produced during the interaction between the electron beam and the sample, enabling the visualization of surface microstructure and elemental composition. Compared to optical microscopes, the exceptional resolving capacity of SEMs establishes them as an essential instrument across numerous industries, particularly those working with functional materials.
Igniting Young Minds: How Whitesboro High School Brought Nanotechnology to Life
Imagine being able to visually explore the nanoscale structures of bugs, pollen, cells, minerals, and more. To zoom thousands of times closer than the naked eye and study intricate details spanning just billionths of a meter. A scanning electron microscope (SEM) is a versatile tool which makes use of an electron beam to scan the surface of a sample to make this vision an achievable reality. Making sense of such small scales requires grasping dimensions exponentially smaller than our direct experience, and an SEM provides a powerful lens to explore these landscapes.

10 Reasons to Use Electrospinning
Electrospinning is a voltage-driven material fabrication process that can be used to produce micro to nano-scale fibers. The electrospinning process is a combination of interacting electric, hydrodynamic, and surface tension forces resulting in “electrohydrodynamic phenomena” which affect the electrospinning solution as a high voltage is applied. The most common basic setup involves a spinneret, high voltage source, material (e.g., polymer) in solution within a reservoir, and a grounded or charged collector.

Why is Camera Resolution important in Optical Tensiometry?
An optical tensiometer, also known as a contact angle goniometer, is an instrument used to characterize material surface properties and interactions between liquid and solid phases. In the simplest experiments, the optical tensiometer places a drop of liquid on the surface and records and analyzes the shape of the drop. The tendency of the drop to spread across the surface is a function of the surface tension of the liquid, gravity, the difference in density of the sample liquid and its surrounding medium, and the properties of the solid surface. Optical tensiometers are used in many industries and scientific disciplines to collect a wide variety of surface measurements, including contact angle, roll-off angle, surface free energy, surface tension, and interfacial tension, among others. The contact angle measurement carried out with an optical tensiometer is the most extensively used method to characterize and quantify the wetting properties of a surface.
Which Electron Detector is Right for Your Application?
Scanning electron microscopy (SEM) is a technique that employs a focused beam of electrons to scan a surface, point by point, to examine a sample’s surface at high resolution. The interaction of the electron beam with the sample surface results in two different kinds of electrons. Backscattered electrons are high-energy electrons originating from the incident beam of SEM that undergoes elastic scattering with the atomic nuclei of the sample.
8 Reasons to Buy a Commercial Electrospinning or Electrospraying System
Electrospinning and electrospraying are electrohydrodynamic processes wherein a polymer solution is used to fabricate fibers or particles, respectively. In the most basic setup, a polymer solution is loaded into a syringe, and it flows through a capillary tube where a high voltage is applied, and the liquid is ejected towards a collector. Depending on the solution properties, fibers or particles are generated during the process.
