Abstract:
The present disclosure provides example embodiments relating to conductive features, such as metal contacts, vias, lines, etc., and methods for forming those conductive features. In some embodiments, a structure includes a first dielectric layer over a substrate, a first conductive feature through the first dielectric layer, the first conductive feature comprising a first metal, a second dielectric layer over the first dielectric layer, and a second conductive feature through the second dielectric layer having a lower convex surface extending into the first conductive feature, wherein the lower convex surface of the second conductive feature has a tip end extending laterally under a bottom boundary of the second dielectric layer.

Claim (Index 30):
The method of  claim 21 , wherein immersing the first conductive feature in the solution comprising DI water removes a native oxide on the surface of the first conductive feature exposed by the opening to define the top surface of the first conductive feature extending directly under the bottommost surface of the second dielectric layer.
