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 16):
The method of  claim 11 , wherein the lower plug is a first lower plug, the via hole is a first via hole, and the recess is a first recess, the method further comprising etching a second via hole into the at least one ILD layer to at least partially expose a top surface of a second lower plug, wherein the wet cleaning process creates a second recess on the second lower plug, and wherein dimensions of the second recess are substantially equal to corresponding dimensions of the first lower plug.
