Methods according to the disclosure identify at least one corner violation including a pair of fill cells of the fill region having a corner-to-corner shape profile that violates a manufacturing specification for the fill region of the IC layout; creating an exclusion layer for the at least one corner violation of the IC layout; removing the at least one corner violation from the fill region using the exclusion layer to form a modified IC layout, wherein at least a portion of each of the pair of fill cells remains in the modified IC layout after removing the at least one corner violation; and manufacturing the modified IC layout to include a fill shape based on the fill region after removing the at least one corner violation, the fill shape being compliant with the manufacturing specification for the fill region of the IC layout.
