    Abstract: A method of metrology target design is described. The method includes determining a sensitivity of a parameter for a metrology target design to an optical aberration, determining the parameter for a product design exposed using an optical system of a lithographic apparatus, and determining an impact on the parameter of the metrology target design based on the parameter for the product design and the product of the sensitivity and one or more of the respective aberrations of the optical system.

    Abstract: A system to, and a method to, select a metrology target for use on a substrate including performing a lithographic simulation for a plurality of points on a process window region for each proposed target, identifying a catastrophic error for any of the plurality of points for each proposed target, eliminating each target having a catastrophic error at any of the plurality of points, performing a metrology simulation to determine a parameter over the process window for each target not having a catastrophic error at any of the plurality of points, and using the one or more resulting determined simulated parameters to evaluate target quality.
