ABSTRACT:
Disclosed are apparatus and methods for optimizing a metrology tool, such as an optical or scanning electron microscope so that minimum human intervention is achievable during the optimization. In general, a set of specifications and an initial input data are initially provided for a particular target. The specifications provide limits for characteristics of images that are to be measured by the metrology tool. The metrology tool is then automatically optimized for measuring the particular target so as to meet one or more of the provided specifications without further significant human intervention with respect to the metrology tool. In one aspect, the input data provided prior to the automated optimization procedure includes a plurality of target locations and a synthetic image of the particular target.
