Abstract
To increase the writing speed of masks, context information can be used to distinguish the attributes of portions of the mask that are critical from attributes, and portions, that are less critical. By using this information, which may be derived from the design context of the features, the mask can be written at a higher speed without sacrificing the accuracy of the important attributes or features.
