    Abstract: The aqueous abrasive-free composition is useful for chemical mechanical polishing of a patterned semiconductor wafer containing a nonferrous metal. The composition includes an oxidizer, an inhibitor for the nonferrous metal, 0 to 15 weight percent water soluble modified cellulose, 0 to 15 weight percent phosphorus compound, 0.005 to 5 weight percent of an acidic polymer, and water. The acidic polymer has a methacrylic acid portion having a carbon number of 4 to 250. The methacrylic acid portion includes either methacrylic acid or an acrylic acid/methacrylic acid copolymer. The acidic polymer including a segment from a mercapto-carboxylic acid chain transfer agent.

    Abstract: This invention is directed to a method for eliminating or reducing pinhole defects in cataphoretically deposited films without interfering with the electrolysis of water needed for electrodeposition. This method comprises decreasing the evolution of hydrogen gas at the cathode by adding a compound to the emulsion. This compound is reduced by the hydrogen produced at the cathode during the electrodeposition. The hydrogen reacts with the this non-gaseous compound rather than becoming hydrogen gas and forming bubbles which lead to pinhole defects.
