Abstract:
An apparatus and method for estimating a parameter of a lithographic process and an apparatus and method for determining a relationship between a measure of quality of an estimate of a parameter of a lithographic process are provided. In the apparatus for estimating the parameter a processor is configured to determine a quality of the estimate of the parameter relating to the tested substrate based on a measure of feature asymmetry in the at least first features of the tested substrate and further based on a relationship determined for a plurality of corresponding at least first features of at least one further substrate representative of the tested substrate, the relationship being between a measure of quality of an estimate of the parameter relating to the at least one further substrate and a measure of feature asymmetry in the corresponding first features.

Claim (Index 24):
The apparatus according to  claim 17 , wherein the processor is further configured, based on radiation emitted by the optical system at three or more wavelengths and diffracted from the plurality of corresponding at least first features of the further substrate, to:\n determine further substrate asymmetry intensity data for the plurality of corresponding at least first features relating to the further substrate; based on the determined further substrate asymmetry intensity data, determine the measure of quality of the estimate of the parameter relating to the at least one further substrate and the measure of feature asymmetry relating to the further substrate; and determine the relationship between the measure of quality of the estimate of the parameter relating to the at least one further substrate and the measure of feature asymmetry in the plurality of corresponding at least first features.
