    Abstract: A method for correcting values of one or more feed-forward parameters used in a process of patterning substrates, the method including: obtaining measured overlay and/or alignment error data of a patterned substrate; and calculating one or more correction values for the one or more feed-forward parameters in dependence on the measured overlay and/or alignment error data.
