Some embodiments provide an iterative method for optimizing a mask layout for producing masks that are used for manufacturing an IC including multiple layers. Each iteration, the method generates a simulated wafer image including predicted manufactured shapes representing components for a layer based on a mask layout. Each iteration, the method compares the simulated wafer image to a target wafer image for the layer to determine whether the predicted manufactured shapes match corresponding shapes in the target wafer image. Each iteration, the method performs an inverse lithography operation to adjust mask shapes of the mask layout based on the comparison. The inverse lithography operation explores different mask layouts and is biased to select mask shapes that ensure that critical regions of the predicted manufactured shapes more perfectly match the corresponding target shapes at expense of less important regions of the predicted manufactured shapes failing to match the corresponding target shapes.
