Abstract: According to an embodiment of the invention there may be provided a system for assigning lithographic mask inspection process parameters. The system may include a search module, a decision module and a memory module. The memory module may be configured to store an expected image expected to be formed on a photoresist during a lithographic process that involves illuminating the lithographic mask. The search module may be configured to search in the expected image for printable features. The decision module may be configured to assign a first lithographic mask inspection process parameter to lithographic mask areas related to printable features and assign a second lithographic mask inspection process parameter to at least some lithographic mask areas that are not associated with printable features. The second lithographic mask inspection process parameter may differ from the first lithographic mask inspection process parameter.

Abstract: A system software product and a method for evaluating a mask, the method including the stages of: defining multiple CD measurement target windows; defining multiple pattern recognition windows such that the multiple CD measurements windows do not overlap the multiple pattern recognition windows, wherein each CD measurement target window and an associated pattern recognition window are positioned within a measurement area that is scannable without introducing a substantial mechanical movement; performing multiple critical dimension measurements of multiple patterns of an object being manufactured by exposing the mask to radiation, wherein the performing comprises using at least one CD measurement target window and at least one pattern recognition window; and evaluating the mask.
