kSA RateRat Pro in action!
Based on the initial calibrated reflectivity of the substrate, kSA RateRat monitors the change in reflectivity and determines in real-time the growth rate and optical constants (n and k) of the deposited film. This real-time analysis is achieved by means of a proprietary algorithm which continuously updates the optical constants of the film, derived from a least-squares fit to the optical reflectivity curve. In this way the film grower has a continuous record of the progress of the film growth during its deposition, including all the critical parameters that are needed to characterize film quality and uniformity.
