Abstract: A method of metrology target design is described. The method includes providing a range or a plurality of values for design parameter of a metrology target and by a processor, selecting, by solving for and/or sampling within the range or the plurality of values for the design parameters, a plurality of metrology target designs having one or more design parameters meeting a constraint for a design parameter of the metrology target.
