Abstract: A method for determining one or more optimized values of an operational parameter of a sensor system configured to measure a property of a substrate is disclosed. The method includes: determining a quality parameter for a plurality of substrates; determining measurement parameter values for the plurality of substrates using the sensor system for a plurality of values of the operational parameter; comparing a substrate to substrate variation of the quality parameter and a substrate to substrate variation of a mapping of the measurement parameter values; and determining the one or more optimized values of the operational parameter based on the comparing.

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.
