The measurement technique commonly used to find the thickness of thin films is spectroscopic ellipsometry. Spectroscopic ellipsometry is a non-destructive and non-contact method that can measure the thickness of transparent and semi-transparent single- and multilayer films. It is widely used in industries such as electronics and semiconductors. This method allows for the simultaneous measurement of film thickness and optical properties such as the refractive index and extinction coefficient. The thickness range where spectroscopic ellipsometry is suitable is between 1nm and 1000nm. However, it may not accurately measure the thickness of thin films based on transparent substrates used in optics. Other techniques such as stylus profilometry and interferometry can also be used for mechanical measurements of film thickness, but they require the presence of a groove or step on the film surface. It is important to consider factors such as the transparency of the material, additional information required, and budget when selecting a measurement technique for thin film thickness.
