Abstract:
The present invention provides a method for determining overlay. The method comprises obtaining an initial overlay estimate relating to a first set of targets and data about a second set of targets, wherein the data for a target comprises an intensity measurement of the target for each of a group of different wavelengths. The method further comprises using the initial overlay estimate to filter data relating to the second set of targets and using the filtered data to estimate overlay on the substrate

Claim (Index 25):
The method of  claim 16 , wherein obtaining data about the first set of targets and/or data about the second set of targets comprises:\n irradiating a target from the respective sets of targets on a substrate, the irradiated target comprising at least a first target structure comprising an overlaid periodic structure having a first deliberate overlay bias and a second target structure comprising an overlaid periodic structure having a second deliberate overlay bias; and detecting radiation scattered by each target structure to obtain for each target structure an asymmetry measurement representing an overall intensity asymmetry which provides the data for that target.
