  • Patent number: 6596151
    Abstract: The present invention provides plating solutions, particularly copper plating solutions, designed to provide uniform coatings on substrates and to provide substantially defect free filling of small features formed on substrates with none or low supporting electrolyte, i.e., which include no acid, low acid, no base, or no conducting salts, and/or high metal ion, e.g., copper, concentration. Defect free filling of features is enhanced by a plating solution containing blends of polyethers (“carrier”) and organic divalent sulfur compounds (“accelerator”), wherein the concentration of the carrier ranges from about 0.1 ppm to about 2500 ppm of the plating solution, and the concentration of the accelerator ranges from about 0.05 ppm to about 1000 ppm of the plating solution. The plating solution is further improved by adding an organic nitrogen compound at a concentration from about 0.01 ppm to about 1000 ppm to improve the filling of vias on a resistive substrate.

  • Publication number: 20020063064
    Abstract: The present invention provides plating solutions, particularly metal plating solutions, designed to provide uniform coatings on substrates and to provide substantially defect free filling of small features, e.g., micron scale features and smaller, formed on substrates with none or low supporting electrolyte, i.e., which include no acid, low acid, no base, or no conducting salts, and/or high metal ion, e.g., copper, concentration. Additionally, the plating solutions may contain small amounts of additives which enhance the plated film quality and performance by serving as brighteners, levelers, surfactants, grain refiners, stress reducers, etc.

  • Patent number: 6379522
    Abstract: The present invention provides plating solutions, particularly metal plating solutions, designed to provide uniform coatings on substrates and to provide substantially defect free filling of small features formed on substrates with none or low supporting electrolyte, i.e., which include no acid, low acid, no base, or no conducting salts, and/or high metal ion, e.g., copper, concentration. Defect free filling of features is enhanced by a plating solution containing blends of polyalkylene glycols (“carrier”) and organic divalent sulfur compounds (“accelerator”), wherein the concentration of the carrier ranges from about 10 ppm to about 2000 ppm of the plating solution, and the concentration of the accelerator ranges from about 0.1 ppm to about 1000 ppm of the plating solution. The plating solution may be further improved by adding 2-amino-5-methyl-1,3,4-thiadiazole which is used at concentrations from 0 ppm to about 20 ppm of the plating solution.
