Abstract

A non-transitory computer-readable medium stores a set of instructions for performing operations to design a mark for assessing a lithographic process. The operations include determining an overlay step that represents a difference between different overlay distances of the different overlay configurations for a design of the mark. The mark includes a first layer mark with first layer components and a second layer mark with second layer components. The first layer mark and the second layer mark are to be projected onto each other via the lithographic process. Each overlay configuration has different overlay distance at which each first layer component is arranged in a first direction of an associated second layer component of the second layer components. The operations include determining a largest overlay distance. The operations also include determining a number of first layer components and/or a number of associated second layer components in each overlay configuration.
