Abstract: A method and apparatus for treating a substrate and, in particular, making secondary adjustments to the results of a primary process applied to the substrate, leading to improved uniformity of the overall process, in which a substrate is positioned on a substrate holder; a scanning a beam of light is directed onto the surface of the substrate; and the amplitude of the scanned beam is varied by location based on a substrate signature.
