Method for Selecting Sample Positions on a Substrate, Method for Providing a Representation of a Model of Properties of a Substrate, Method of Providing a Representation of the Variation of Properties of a Substrate Across the Substrate and Device Manufacturing Method

摘要

A method for selecting sample positions on a substrate from a set of all available sample positions is provided, in which a representation of a model, which may represent the variation of one or more properties across the substrate, is analyzed in order to identify the sample positions having the greatest effect on the model.
