Abstract:
In a semiconductor device, through hole vias or through silicon vias (TSV) may be formed so as to include an efficient stress relaxation mechanism, for instance provided on the basis of a stress relaxation layer, in order to reduce or compensate for stress forces caused by a pronounced change in volume of the conductive fill materials of the through hole vias. In this manner, the high risk of creating cracks and delamination events in conventional semiconductor devices may be significantly reduced.
