Abstract:
1. A method, comprising: creating an overall target pattern comprised of a plurality of line-type features including an odd-jogged feature, wherein the each of the plurality of features are positioned above separate routing tracks, each of which are separated from an adjacent routing track by a pitch, said odd-jogged feature having a crossover region that connects first and second line portions, wherein said crossover region spans a distance corresponding to an odd number of pitches, said crossover region having a first dimension in a first direction that is parallel to a long-axis of one of said first and second line portions that is greater than a second dimension of each of said first and second line portions in a second direction that is transverse to said first direction; decomposing said overall target pattern into a first sub-target pattern and a second sub-target pattern, wherein said first sub-target pattern comprises one of said first and second line portions and a first portion of said crossover region and said second sub-target pattern comprises the other of said first and second line portions and a second portion of said crossover region; generating a first set of mask data corresponding to said first sub-target pattern; and generating a second set of mask data corresponding to said second sub-target pattern.
