APPLICATION

Materials science, which involves discovering and designing new materials, incorporates elements of physics, chemistry, and engineering. With the help of scanning electron microscope, material scientists are now able to analyze microsctructure, crystal structure, chemistry, and surface structure of solid samples with great depth of focus and resolution down to the nanoscale.

Using COXEM’s SEM with energy-dispersive X-ray spectroscopy (EDS), scientists are also able to perform qualitative chemical analysis, such as obtaining elemental maps that show which elements are in which part of a sample. With the BSE detector, multiple phases in a sample can be easily discriminated and documented based on the atomic number.

SEMICONDUCTORS & ELECTRONICS

Flexibility in selecting and using operating parameters (accelerating voltage, specimen tilt, scan line time, etc) as well as correct analytical procedures are needed to obtain the maximum information when examining semiconductors and microelectronic devices.
