  • Acid copper electroplating solutions
    Publication number: 20040187731
    Abstract: Improved acid copper electroplating bath compositions are disclosed. The improved bath solutions contain at least one of a carrier; a water-soluble, mercapto-containing organic brightener; and a leveler which comprises an organic compound containing single or multiply charged centers in acidic bath solution. These electroplating bath compositions are used to copper plate advanced interconnects on semiconductor devices.
