Automatic selection of metrology target measurement recipes

Last updated:

Abstract:

A method including performing a first simulation for each of a plurality of different metrology target measurement recipes using a first model, selecting a first group of metrology target measurement recipes from the plurality of metrology target measurement recipes, the first group of metrology target measurement recipes satisfying a first rule, performing a second simulation for each of the metrology target measurement recipes from the first group using a second model, and selecting a second group of metrology target measurement recipes from the first group, the second group of metrology target measurement recipes satisfying a second rule, the first model being less accurate or faster than the second model and/or the first rule being less restrictive than the second rule.
