    Abstract: The present invention relates to chemical compositions and methods of use for cleaning CMP equipment, including the interiors of delivery conduits carrying CMP slurry to the necessary sites. The chemical compositions of the present invention are also useful for post-CMP cleaning of the wafer itself. Three classes of cleaning compositions are described, all of which are aqueous solutions. One class operates in a preferable pH range from about 11 to about 12 and preferably contains one or more non-ionic surfactants, one or more simple amines, a surfactant or sticking agent such as one or more soluble dialcohol organic compounds and one or more quaternary amines. A second class of cleaning composition operates in a preferable pH range of approximately 8.5 and contains citric acid and oxalic acid. A third class of compositions is acidic, having a preferable pH range from about 1.5 to about 3, preferably containing at least one oxidizing acid, at least one chelating agent, at least one sticking agent and at least one anionic surfactant. HF and KOH are substantially absent from the preferred compositions of the present invention. Some compositions of the present invention are shown to be advantageously used for cleaning the slurry distribution system of CMP apparatus.

    Abstract: An aqueous cleaning composition for post copper chemical mechanical planarization is provided. The composition comprises an organic base, a copper etchant, an organic ligand, a corrosion inhibitor, and water, wherein the organic base is in a concentration of at least 200 ppm, the copper etchant is in a concentration of at least 200 ppm, the organic ligand is in a concentration of at least 50 ppm, and the corrosion inhibitor is in a concentration of at least 10 ppm. When used in the post copper chemical mechanical planarization cleaning procedure, the aqueous cleaning composition can effectively remove the residual contaminants from the wafer surface and reduce the defect counts on the wafer surface, while simultaneously, impart the wafers with a better surface roughness.

    Abstract: In one embodiment, a metal loss inhibitor concentrate is provided which contains water, (A) an amount of a component of dissolved organic compounds and polymers that contain at least two hydroxy moieties per molecule and an average of at least 0.4 hydroxy moieties per carbon atom: (B) an amount of a thiourea component; and (C) an amount of a dissolved component containing aryl and quaternary ammonium moieties; and, optionally: (D) an amount of a wetting agent, such as a component of an ethoxylate of an alcohol having Formula R?1#191-OH wherein R?1#191 is a saturated or unsaturated, straight-chain or branched aliphatic having from 12 to 80 carbon atoms. Such solutions form useful inhibitor concentrates when combined with aqueous chelating cleaning solutions, wherein such solutions, when contacted with a metal surface, are effective in removing scale, smut and other deposits from the metal surface but exhibit a reduced tendency to attack or unduly etch the metal itself, or to inhibit the subsequent desired oxidation and dissolution of metallic copper deposits.
