  • Patent number: 7144849
    Abstract: A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined. Following use of the composition, the non-used portion of the composition can be disposed of or be reactivated by the addition of a chelating agent.

  • Patent number: 6306201
    Abstract: This invention relates to a bivalent iron compound comprising a bivalent iron salt, an amino acid and a reducing material. It is known that bivalent iron salts exhibit specific effects in wide applications, for example, agricultural applications such as modification of soil quality, fishing applications such as quality preservation of fishes, medical applications such as treatment of diseases and industrial applications such as prevention of metal corrosion and purification of waste water and exhaust gas. However, the conventional bivalent iron salts suffer a problem that they cannot exhibit such effect for extended periods. This invention was successful in chemically stabilizing the bivalent iron salts by adding amino acids and reducing materials so as to sustain the effects inherent in the bivalent iron salts and to enable utilization thereof in industrial applications.

  • Patent number: 5698512
    Abstract: Water soluble polymers are prepared from an allyloxybenzenesulfonic acid monomer, a methallyl sulfonic acid monomer, a copolymerizable nonionic monomer, and a copolymerizable olefinically unsaturated carboxylic acid monomer. Aqueous compositions containing the water soluble polymers and nonionic surfactants are stable to phase separation of the polymer from the nonionic surfactant.

  • Patent number: 5672577
    Abstract: A stripping and cleaning composition for removing resists and etching residue from substrates containing hydroxylamine and at least one alkanolamine is described. Further, a cleaning composition for removing etching residue from semiconductor substrates containing hydroxylamine, at least one alkanolamine, at least one chelating agent, and water is described. The preferred chelating agent is 1,2-dihydroxybenzene or a derivative thereof. The chelating agent provides added stability and effectiveness to the cleaning composition.

  • Patent number: 5531934
    Abstract: The present invention provides a method of inhibiting corrosion of ferrous metals in aqueous systems. The corrosion is inhibited by adding an effective amount of one or more poly(amino acids) to the aqueous system. Aqueous systems include for example water treatment systems and equipment used for detergent applications. The poly(amino acids) comprise a reaction product of at least one compound selected from amino acids, amic acids, ammonium salts of monoethylenically unsaturated dicarboxylic acids, ammonium salts of hydroxypolycarboxylic acids and combinations thereof.In one embodiment the poly(amino acids) are added to detergent solutions to inhibit corrosion in equipment for detergent applications. In another embodiment, corrosion inhibitors comprising one or more homopolymers of amino acids and one or more pyrophosphates are added to aqueous systems to inhibit corrosion.
