    Abstract: The present disclosure relates to an arrangement and a method of performance-aware buffer zone placement for a high-density array of unit cells. A first feature density of the array is measured and maximum variation for a parameter within a unit cell is determined. A look-up table of silicon data is consulted to predict a buffer zone width and gradient value that achieves a variation that is less than the maximum variation for the unit cell. The look-up table contains a suite of silicon test cases of various array and buffer zone geometries, wherein variation of the parameter within a respective test structure is measured and cataloged for the various buffer zone geometries, and is also extrapolated from the suite of silicon test cases. A buffer zone is placed at the border of the array with a width that is less than or equal to the buffer zone width.

    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.
