Abstract:
A semiconductor device structure is 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. The semiconductor device structure further includes a conductive via surrounded by the dielectric layer and electrically connected to the conductive feature. The conductive via has a lower end and an upper end larger than the lower end, and the conductive via has a side surface curved inward.

Claim (Index 1):
A semiconductor device structure, comprising:\n a semiconductor substrate; a conductive feature over the semiconductor substrate, wherein the conductive feature is a conductive line; a first dielectric layer over the conductive feature and the semiconductor substrate, wherein the first dielectric layer is made of silicon oxide, carbon-containing silicate glass, hydrogen-containing silicate glass, fluorine-containing silicate glass, or a combination thereof; and a conductive via surrounded by the first dielectric layer and electrically connected to the conductive feature, wherein the conductive via has a lower end in contact with the conductive feature and an upper end larger than the lower end, the conductive via has a side surface with a surrounded portion extending from a topmost surface of the first dielectric layer to a bottommost surface of the first dielectric layer, the entire surrounded portion of the side surface of the conductive via curves inward, the entire surrounded portion of the side surface is in direct contact with the first dielectric layer, the lower end of the conductive via has a width smaller than a width of the conductive feature, the conductive via comprises a first seed layer and a first conductive layer, the first seed layer is between the first conductive layer and the first dielectric layer, and a top surface of the first seed layer is substantially coplanar with a surface of the first conductive layer.
