The compositions and methods herein relate to the method for the removal of residues and contaminants from metal or dielectric surfaces. Particularly, a composition and method of cleaning residues after chemical mechanical polishing of a copper or aluminum surface of the semiconductor substrates. A method of cleaning semiconductor substrates comprising contacting the substrates with a solution of water, and sufficient amount of alkyl diphosphonic acid comprising alkyl diphosphonic acid selected from the group of 1 hydroxyethane 1,1 diphosphonic acid, methylene disphosphonic acid, hydroxymethylene diphosphonic acid, dichloromethylene disphosphonic acid, hydroxycyclohexylmethylene disphosphonic acid, 1-hydroxy-3-aminopropane 1,1 diphosphonic acid, 1-hydroxy-4-aminobutane 1,1 diphosphonic acid mixed with dodecylbenzenesulfonic acid, xylenesulfonic acid, toluenesulfonic acid, phosphonoformic acid, sulfamic acid, 2-amino ethane sulfonic acid, or fluoroboric acid or an organic carboxylic acid and pH is adjusted to from greater than 6 to about 10 with a metal ion free base, and a surfactant. |
