Abstract:
A method of determining a control setting for a lithographic apparatus. The method includes obtaining a first correction for a current layer on a current substrate based on first metrology data associated with one or more previous substrates, and obtaining a second correction for the current layer on the current substrate. The second correction is based on a residual determined based on second metrology data associated with a previous layer on the current substrate. The method further includes determining the control setting for the lithographic apparatus for patterning the current layer on the current substrate by combining the first correction and the second correction.
