What Is Scanning Electron Microscopy SEM?
Scanning Electron Microscopy (SEM) is an advanced analytical surface technique used to study morphology, microstructure, and composition in materials at submicron to nanometer scales. SEM focuses electrons as a beam to produce high-resolution images and analytical data. It is becoming an indispensable technique for industries with decreasing material dimensions and tolerances, such as microelectronics, semiconductors, aerospace, and biomedical devices.
It provides detailed information on surface topography, material defects, and elemental composition, thereby supporting quality control, failure analysis, and product optimization.
Applications and Benefits of Scanning Electron Microscopy SEM Testing
Scope
SEM enables detailed characterization of solid materials by analyzing:
- Surface morphology and topography (3D-like imaging)
- Material contrast based on atomic number
- Elemental composition through Energy-Dispersive X-ray Spectroscopy (EDS)
It is suitable for conductive and non-conductive materials (with appropriate sample preparation) across a wide range of industrial and research applications.
Applications
- Semiconductor inspection and microchip assembly analysis
- Failure analysis of electronic components and coatings
- Evaluation of thin films and surface coatings
- Identification of microstructures, inclusions, and contaminants
- Corrosion and fracture analysis of metals and alloys
- Polymer degradation and filler dispersion analysis
- Mineral identification and ore quality assessment
Benefits
- Delivers ultra-high-resolution imaging beyond optical microscopy
- Combines imaging with elemental and compositional analysis
- Detects early-stage defects, reducing product failure and warranty costs
- Supports product development, quality assurance, and root-cause analysis
- Applicable across diverse industries from aerospace to biomedicine
Our Testing Procedure
Specimen Preparation
Solid samples are cleaned and, if non-conductive, coated with gold or carbon to prevent charging.
1Electron Beam Scanning
A focused electron beam scans the sample surface at controlled accelerating voltages (typically 0.1–30 kV).
2Signal Detection
Secondary electrons, backscattered electrons, and X-rays are detected using dedicated detectors.
3Data Collection & Imaging
Signals are processed to generate high-resolution images and elemental maps (EDS).
