ABSTRACT:
A method and apparatus for redirecting void diffusion away from vias in an integrated circuit design includes steps of forming an electrical conductor in a first electrically conductive layer of an integrated circuit design, forming a via between a distal end of the electrical conductor and a second electrically conductive layer of the integrated circuit design, and reducing tensile stress in the electrical conductor to divert void diffusion away from the via.
