Abstract
A variety of techniques is used for the measurement of thin film thicknesses of the order of one micrometer. These techniques include stylus profilometry, multiple beam interferometry, dual beam interferometry, guided waves, channel spectra and ellipsometry. The principles underlying each of the techniques are discussed and where available, experimental comparisons of the techniques are presented. Advantages, disadvantages, and sources of error are also discussed.
