... Abstract Measuring the thickness of thin films can be accomplished in many ways. This article focuses on the optical method of single-wavelength ellipsometry, two multiple-wavelength methods of reflectometry and spectroscopic ellipsometry for measuring the thickness of thin films. The general...

Stress gradients can exist in the deposited film due to the growth mode and differing thermal histories of the various layers of the film. These stresses can give the outermost layer of the film a tensile stress compared to...
