Abstract:
A method of determining positions of marks, the marks comprising periodic structures, at least some of the structures comprising periodic sub-structures, the sub-structures having a smaller period than the structures, the marks formed with positional offsets between the sub-structures and structures, the positional offsets caused by a combination of both known and unknown components, the method comprising illuminating a plurality of the marks with radiation having different characteristics, detecting radiation diffracted by the marks using one or more detectors which produce output signals, discriminating between constituent parts of the signals, the discriminating based on a variation of the signals as a function of spatial positions of the marks on a substrate, selecting at least one of the constituent parts of the signals, and using the at least one selected constituent part, and information relating to differences between the known components, to calculate a corrected position of at least one mark.

Claim (Index 12):
A lithographic apparatus comprising:\n a patterning subsystem configured to transfer a pattern to a substrate; a measuring subsystem configured to measure positions of the said substrate in relation to the patterning subsystem, wherein the patterning subsystem is arranged to use the positions measured by the measuring subsystem to apply the pattern at a desired position on the substrate and wherein the measuring subsystem is arranged to position the applied pattern by reference to measured positions of marks provided on the substrate and wherein the measuring subsystem is arranged to calculate the measured positions of the marks by the method as claimed in  claim 1 .
