Abstract :
In this investigation the stress-induced voiding (SIV) behavior of via structures with different geometries was tested. A variation of via sizes, aspect ratios, and widths of connected metal lines was studied. The resistance drift and its temperature dependence behavior showed sensitivity to the structure size. This can be explained by the size-dependence of mechanical stress in the metallization
