Ellipsometry and Reflectometry Systems
Advanced Optical Metrology Solutions from R&D to Production
Based on non-contact optical techniques, FilmTek tools simultaneously measure multiple-angle and multi-modal data to determine film thickness and refractive index. By measuring multiple angles of incidence, a wavelength shift is introduced between spectra collected at different angles. The wavelength shift between the spectra is only a function of the refractive index of the film and the angle difference between the spectra. By independently determining refractive index from a wavelength shift (as opposed to extracting index information from amplitude changes), FilmTek tools have best-in-class performance for film thickness and refractive index measurement. This level of performance allows FilmTek tools to address applications that otherwise may not be possible with more conventional ellipsometry or reflectometry methods.
