Spectroscopy in Thin Film Fabrication

Posted on: July 23rd, 2019

Used across many industries such as semiconductors, technology gadgets, and optical elements, thin films carry a very important roll in our world. Because of its wide range in applicability, the accuracy of thickness and repeatability are extremely important.  Therefore, a measurement technique is crucial to ensure surface thickness accuracy. Presently there are three common techniques to qualitate surface thickness; stylist profilometry, ellipsometry, and spectral reflectance. In this application note, we discuss in detail the spectral reflectance technique and a typical setup using Avantes spectroscopy equipment.
