Abstract:
There is disclosed a method of measuring a process parameter for a manufacturing process involving lithography. In a disclosed arrangement the method comprises performing first and second measurements of overlay error in a region on a substrate, and obtaining a measure of the process parameter based on the first and second measurements of overlay error. The first measurement of overlay error is designed to be more sensitive to a perturbation in the process parameter than the second measurement of overlay error by a known amount.

Claim (Index 17):
The lithographic apparatus of  claim 16 , wherein the process parameter comprises an asymmetry in a feature of a target structure formed on the substrate by a lithographic process.
