    Abstract: A method comprises: accessing data representing a layout of a layer of an integrated circuit (IC) comprising a plurality of polygons defining circuit patterns to be divided among a number (N) of photomasks for multi-patterning a single layer of a semiconductor substrate, where N is greater than one. For each set of N parallel polygons in the layout closer to each other than a minimum separation for patterning with a single photomask, at least N?1 stitches are inserted in each polygon within that set to divide each polygon into at least N parts, such that adjacent parts of different polygons are assigned to different photomasks from each other. Data representing assignment of each of the parts in each set to respective photomasks are stored in a non-transitory, computer readable storage medium that is accessible for use in a process to fabricate the N photomasks.
