Latest Patents

Stuart Farquharson holds a patent for a method titled "Film thickness and free carrier concentration analysis method." This method determines the thickness and the free carrier concentration of at least one layer of a structure. An exposed surface of the structure is irradiated using spectral radiation, and the measured reflectance spectrum is compared to a calculated spectrum. Using algorithms that include terms representative of complex refractive indices, layer thickness, dielectric constants, and free carrier concentrations, values are iteratively assigned to the thickness and free carrier concentration parameters. This process produces a best fit relationship between the compared spectra, allowing for accurate determination of those parameters.
