    Abstract: Provided is a plating method of a circuit substrate comprising a conductive pattern in which a metal layer containing at least silver and copper is exposed on an outer surface. The plating method comprises: step (A) of treating the circuit substrate with a first liquid agent containing an oxidizing agent; step (B) of treating the circuit substrate after the step (A) with a second liquid agent which dissolves copper oxide, and thereby removing copper oxide from the conductive pattern's surface; step (C) of treating the circuit substrate after the step (B) with a third liquid agent whose rate of dissolving silver oxide (I) at 25° C. is 1000 times or more faster than its rate of dissolving copper (0) at 25° C., and thereby removing silver oxide from the conductive pattern's surface; and step (D) of performing electroless plating on the conductive pattern of the circuit substrate after the step (C).

    Abstract: An environmentally acceptable and comparatively safe acid cleaning solution containing sulfuric acid, water and amine containing inhibitors that adequately remove oxidation or contaminants from surfaces without excessively damaging equipment. The sulfuric acid is effective in removing impurities and contaminants, while the amine moieties or amine salts reduce the otherwise damaging effect of sulfuric acid on equipment and on human skin and tissue.

    Abstract: The various embodiments described in the specification provide improved mechanisms of removal of unwanted deposits on the bevel edge to improve process yield. The embodiments provide apparatus and methods of treating the bevel edge of a copper plated substrate to convert the copper at the bevel edge to a copper compound that can be wet etched with a fluid at a high etch selectivity in comparison to copper. In one embodiment, the wet etch of the copper compound at high selectivity to copper allows the removal of the non-volatile copper at substrate bevel edge in a wet etch processing chamber. The plasma treatment at bevel edge allows the copper at bevel edge to be removed at precise spatial control to about 2 mm or below, such as about 1 mm, about 0.5 mm or about 0.25 mm, to the very edge of substrate. In addition, the apparatus and methods described above for bevel edge copper removal do not have the problems of copper etching fluid being splashed on the device regions to cause defects and thinning of copper films. Therefore, device yield can be greatly improved.

    Abstract: This disclosure discusses cleaning of semiconductor wafers after the Chemical-Mechanical Planarization (CMP) of the wafer during the manufacturing of semiconductor devices. Disclosed is an acidic chemistry for the post-CMP cleaning of wafers containing metal, particularly copper, interconnects. Residual slurry particles, particularly copper or other metal particles, are removed from the wafer surface without significantly etching the metal, leaving deposits on the surface, or imparting significant organic (such as carbon) contamination to the wafer while also protecting the metal from oxidation and corrosion. Additionally, at least one strong chelating agent is present to complex metal ions in solution, facilitating the removal of metal from the dielectric and preventing re-deposition onto the wafer. Using acidic chemistry, it is possible to match the pH of the cleaning solution used after CMP to that of the last slurry used on the wafer surface.
