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 15):
A semiconductor device structure, comprising:\n a semiconductor substrate; a conductive feature over the semiconductor substrate; a dielectric layer over the conductive feature and the semiconductor substrate, wherein the 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 and an upper end larger than the lower end, the conductive via has a side surface extending from a topmost surface of the dielectric layer to a bottommost surface of the dielectric layer, the side surface of the conductive via curves inward, and an entirety of the side surface is in direct contact with the first dielectric layer.
