    Abstract: Disclosed is a method for controlling a process of manufacturing semiconductor devices, the method comprising: obtaining a first control grid associated with a first lithographic apparatus used for a first patterning process for patterning a first substrate; obtaining a second control grid associated with a second lithographic apparatus used for a second patterning process for patterning a second substrate; based on the first control grid and second control grid, determining a common control grid definition for a bonding step for bonding the first substrate and second substrate to obtain a bonded substrate; obtaining bonded substrate metrology data comprising data relating to metrology performed on the bonded substrate; and determining a correction for performance of the bonding step based on said bonded substrate metrology data, the determining a correction comprising determining a co-optimized correction for the bonding step and for the first patterning process and/or second patterning process.

    Abstract: Disclosed is a method for determining an intra-field correction for control of a lithographic apparatus configured for exposing a pattern on an exposure field of a substrate, the method comprising: obtaining metrology data for use in determining the intra-field correction; determining an accuracy metric indicating a lower accuracy where the metrology data is not reliable and/or where the lithographic apparatus is limited in actuating a potential actuation input which is based on the metrology data; and determining said intra-field correction based at least partially on said accuracy metric.
