  • Corrosion-resistant electrode structure for integrated circuit decoupling capacitors
    Patent number: 6555912
    Abstract: A corrosion resistant electrode structure for interconnecting a decoupling capacitor to a substrate is disclosed. In an exemplary embodiment of the invention, the electrode structure includes a first chromium layer formed upon the capacitor and a first nickel layer formed upon the first chromium layer. A noble metal conductive layer is then formed upon the first nickel layer and a second nickel layer is formed upon said noble metal conductive layer. The second nickel layer has a thickness which is greater than a thickness of the first nickel layer. A second chromium layer is then formed upon the nickel layer.
    Type: Grant
