Abstract
In one embodiment, a semiconductor device includes one or more metallizations, such as, e.g., Cu-RDL metallizations, provided on a passivation layer over a dielectric layer. A via is provided through the passivation layer and the dielectric layer in the vicinity of the corners of the metallization. The via may be a 'dummy' via without electrical connections to an active device and may be provided at a distance between approximately 1 micron (10m.) and approximately 10 micron (10m.) from each one of said converging sides landing on an underlying metal layer.
