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 34):
A computer program comprising instructions which, when executed on at least one processor, cause the at least one processor to control an apparatus to carry out a method for estimating a parameter of a lithographic process that has been undertaken on a tested substrate, the estimation being based on regression analysis data that has been determined by a regression analysis of asymmetry intensity data that has, in turn, been determined using radiation emitted by an optical system at one or more wavelengths and diffracted by at least first features of the tested substrate, the method comprising:\n determining 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.
