摘要： A method for forming exposure masks for imaging a target pattern having features to be imaged on a substrate in a multi-exposure process. The method includes the steps of generating a set of decomposition rules defining whether a given feature of the target pattern is assigned to a first exposure mask or a second exposure mask; applying the decomposition rules to each of the features in the target pattern so as to assign each of the features in the target pattern to one of the first exposure mask or second exposure mask; and generating the first exposure mask and the second exposure mask containing the respective features assigned to each mask.

摘要： A method of generating complementary masks based on a target pattern having features to be imaged on a substrate for use in a multiple-exposure lithographic imaging process is disclosed. The method includes defining an initial H-mask and an initial V-mask corresponding to the target pattern; identifying horizontal critical features in the H-mask and vertical critical features in the V-mask; assigning a first phase shift and a first percentage transmission to the horizontal critical features, which are to be formed in the H-mask; and assigning a second phase shift and a second percentage transmission to the vertical critical features, which are to be formed in the V-mask. The method further includes the step of assigning chrome to all non-critical features in the H-mask and the V-mask.

摘要： A method of generating complementary masks for use in a dark field double dipole imaging process. The method includes the steps of identifying a target pattern having a plurality of features, including horizontal and vertical features; generating a horizontal mask based on the target pattern, where the horizontal mask includes low contrast vertical features. The generation of the horizontal mask includes the steps of optimizing the bias of the low contrast vertical features contained in the horizontal mask; and applying assist features to the horizontal mask. The method further includes generating a vertical mask based on the target pattern, where the vertical mask contains low contrast horizontal features. The generation of the vertical mask includes the steps of optimizing the bias of low contrast horizontal features contained in the vertical mask; and applying assist features to the vertical mask.
