    Abstract: A method and system for dispositioning defects in a photomask are provided. A method for dispositioning defects in a photomask includes analyzing photomask topography data including data representing a design topology of at least a first photomask, the first photomask corresponding to a first layer in a photolithographic process. Based at least on the analysis, one or more safe regions of the first photomask are identified, each safe region corresponding to a region of the first layer insensitive to potential defects located in the first photomask.
