Abstract

In this article we present a pairwise coloring (PWC) approach to tackle the layout decomposition problem for triple patterning lithography (TPL). The main idea is to reduce the problem to a set of bi-coloring problems. The overall solution is refined by applying a bi-coloring method for pairs of color sets per pass. One obvious advantage of this method is that the existing double patterning lithography (DPL) techniques can be reused effortlessly. Moreover, we observe that each pass can be fulfilled efficiently by integrating an SPQR-tree-graph-division-based bi-coloring method. In addition, to prevent the solution getting stuck in the local minima, an adaptive multi-start (AMS) approach is incorporated. Adaptive starting points are generated according to the vote of previous solutions. The experimental results show that our method is competitive with other works on both solution quality and runtime performance.
