Abstract
A metrology system includes a controller communicatively coupled to a metrology tool. The controller may generate a three-dimensional model of a sample, generate a predicted metrology image corresponding to a predicted analysis of the sample with the metrology tool based on the three-dimensional model, evaluate two or more candidate metrology recipes for extracting the metrology measurement from the one or more predicted metrology images, select, based on one or more selection metrics, a metrology recipe from the two or more candidate metrology recipes for extracting a metrology measurement from an image of the structure from the metrology tool, receive an output metrology image of a fabricated structure from the metrology tool based on a metrology measurement of the fabricated structure, and extract the metrology measurement associated with the fabricated structure from the output metrology image based on the metrology recipe.
