Cleaning solutions for removing residuals from the surface of an integrated
circuit device. Such cleaning solutions find particular application in the fabrication
of a dual damascene structure following removal of excess portions of a silver-containing
metal layer from a device surface. The cleaning solutions facilitate removal of
particulate residuals as well as unremoved portions of the metal layer in a single
cleaning process. The cleaning solutions are dilute aqueous solutions containing
hydrogen peroxide and at least one acidic component and are substantially free
of particulate material. Acidic components include carboxylic acids and their salts.
