Abstract:
In one exemplary aspect, a method comprises providing a semiconductor structure having a substrate, one or more first dielectric layers over the substrate, a first metal plug in the one or more first dielectric layers, and one or more second dielectric layers over the one or more first dielectric layers and the first metal plug. The method further comprises etching a via hole into the one or more second dielectric layers to expose the first metal plug, etching a top surface of the first metal plug to create a recess thereon, and applying a metal corrosion protectant comprising a metal corrosion inhibitor to the top surface of the first metal plug.

Claim (Index 23):
The method of  claim 21 , wherein the metal corrosion protectant is applied to the top surface of the first metal plug after the recess has reached a pre-defined target profile.
