Abstract

A semiconductor interconnect architecture provides a reduction in the intersection of vias on the last layer ('VL') and holes in the last thin metal layer ('MLHOLE') without degradation of the product yield or robustness, or increases copper dishing. The mutation of some dense redundant VLs to MLHOLEs decreases the number of intersections between VLs and MLHOLEs.
