Abstract:
A structure and a formation method of a semiconductor device structure are provided. The semiconductor device structure includes a semiconductor substrate and a conductive feature over the semiconductor substrate. The semiconductor device structure also includes a dielectric layer over the conductive feature and the semiconductor substrate and a via hole in the dielectric layer. The via hole has an oval cross section. The semiconductor device structure further includes a trench in the dielectric layer, and the via hole extends from a bottom portion of the trench. The trench has a trench width wider than a hole width of the via hole. In addition, the semiconductor device structure includes one or more conductive materials filling the via hole and the trench and electrically connected to the conductive feature.

Claim (Index 23):
The method of  claim 21 , further comprising:\n removing the mask layer before filling the via hole with protective material.
