    • Spectroscopy is a technique that uses the interaction of energy with a sample to perform an analysis. Spectroscopy pertains to the dispersion of an object's light into its component colors (i.e. energies). The data that is obtained from spectroscopy is called a spectrum. A spectrum is a plot of the intensity of energy detected versus the wavelength (or mass or momentum or frequency, etc.) of the energy. In simplest terms, spectroscopy requires an energy source and a device for measuring the change in the energy source after it has interacted with the sample (a spectrophotometer or interferometer). There are several instruments that are used to perform a spectroscopic analysis and produce results. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light.

Ravindra The technique of Fourier transform infrared (FTIR) reflectometry has been advanced to characterize the thickness and optical properties of thin films commonly used in advanced integrated circuits (I.C.s). This article describes the demonstration of a new, high accuracy reflectometer to characterize the reflectance of ultrathin gate oxides and chemically amplified deep ultraviolet (UV) photoresist thin films. The gate oxide reflectance data were related to the deposition time to model the thermal oxidation growth kinetics.
