Abstract:
A method for generating mask layout data for lithography simulation, in whichoriginal data that define an original layout are prescribed, new data that define a new layout are automatically calculated proceeding from the original data, and in which the new layout is more similar, with regard to the geometry, to a mask that is produced or can be produced using the original data than to the original layout, wherein the new data are calculated on the basis of rules that are based on deviations in the geometry of a layout from a mask that is produced according to this layout or a mask that is modeled proceeding from this layout with simulation of the steps of the production process, the rules containing geometric calculation specifications for defining the boundaries of a structure at a position of the new layout depending on the length and/or the area of a reference structure located at the same position in the original layout and/or depending on the distance between the reference structure and adjacent structures.
