Abstract:
A method includes forming a first dielectric layer over a wafer, etching the first dielectric layer to form an opening, filling a tungsten-containing material into the opening, and performing a Chemical Mechanical Polish (CMP) on the wafer. After the CMP, a cleaning is performed on the wafer using a weak base solution.

Claim (Index 16):
A structure comprising:\n a conductive feature comprising:\n a first metal layer; \n a metal nitride layer between opposing portions of the first metal layer; and \n a second metal layer between opposing portions of the metal nitride layer; \n a dielectric region, with the conductive feature being located in the dielectric region; a first dielectric layer over and contacting the dielectric region; and a second dielectric layer between the conductive feature and the first dielectric layer, and a bottom surface of the first dielectric layer is in contact with top surfaces of both the conductive feature, the second dielectric layer, and the dielectric region, wherein the second dielectric layer comprises organic amin.
