SEM Lab, Inc. has developed a method for measuring thickness of thin film deposits on various substrates, including multiple layers of different materials, using EDS data. The method is extremely efficient and is therefore a cost effect alternative to conventional and FIB microsection techniques (approximately half the cost). Scanning electron microscope images of an aerogel microparticle with visible shellac coating layer, cross-sectioned with focused ion beam. . Before measuring the layer thickness, food-grade spherical aerogel microparticles were produced using the emulsion method with heat-induced gelation of the protein solution, representing the dispersed .

Other advantages of using SEM and TEM for measuring active layer thickness include that SEM and TEM instrumentation are readily available in many research facilities due to their wide use in other research fields, the measurement of thickness is a direct measurement and does not require any assumptions about the properties of the active layer .A non-destructive method for measuring the thickness of thin films deposited on a substrate has been developed with a conventional scanning electron microscope (SEM) equipped with ultra-thin window energy dispersive X-ray spectrometer (EDS). It is based physically on that the penetrant depth of electrons decreased as the accelerate voltage of incident electron lowered. .

In the semiconductor industry, accurate and efficient measurement of epitaxial (Epi) layer thickness is paramount. The Fourier transform infrared (FTIR) technique is often used to measure the thickness of those layers to help ensure quality. The Importance of Epitaxial Layers Thickness. The US. To measure the thickness (d) of a thin film, the complex refractive indices and incident angles should be known in advance.The total reflectance at each wavelength according to d can be calculated using such information. As a result, the thin-film thickness d can be determined as a specific value which makes the modeled total reflectance spectrum most .
