  • Limiting the loss of tin through oxidation in tin or tin alloy electroplating bath solutions
    Patent number: 6923899
    Abstract: Provided for is a solution for use in the electroplating of tin and tin alloys comprising a basis solution comprising an acid, optionally a salt thereof, the acid selected from the group consisting of fluoboric acid, an organic sulfonic acid, a mineral acid, or a combination thereof; divalent tin ions; and an antioxidant comprising a hydroxy benzene sulfonic acid or salt thereof, in an amount effective to prevent the oxidation of divalent tin ions. Also provided for is a method for electroplating comprising electroplating a substrate using an electroplating solution comprising a hydroxy benzene sulfonic acid or salt thereof in an amount effective to decrease the oxidation of tin ions.
