Redundant Via Insertion in Restricted Topology Layouts

  title={Redundant Via Insertion in Restricted Topology Layouts},
  author={Kevin W. McCullen},
  journal={8th International Symposium on Quality Electronic Design (ISQED'07)},
In this paper, the authors describe the application of redundant via insertion (RV) to the restricted topologies proposed for gridded and alternating phase shift mask layouts. Adding redundant vias has been shown to improve the yield and reliability of designs. The paper shows that it is possible to successfully add redundant vias, provided that the gridded layer is adjacent to a layer that can receive the additional layout complexity of the off-direction routing necessary to add additional… CONTINUE READING
