Abstract

A structure and a formation method of a semiconductor device are provided. The semiconductor device structure includes an interconnection structure over a semiconductor substrate. The semiconductor device structure includes a conductive pillar over the interconnection structure. The conductive pillar has a protruding portion extending towards the semiconductor substrate. The semiconductor device structure includes an upper conductive via between the conductive pillar and the interconnection structure. A center of the upper conductive via is laterally separated from a center of the protruding portion by a first distance. The semiconductor device structure includes a lower conductive via between the upper conductive via and the interconnection structure. The lower conductive via is electrically connected to the conductive pillar through the upper conductive via. A center of the lower conductive via is laterally separated from the center of the protruding portion by a second distance that is shorter than the first distance.
