Uniformity across a 4" wafer is around 5% for the standard processes (the edge being slightly thicker than the center of the sample). Running at high current densities will deposit a nickel layer that is quite soft. Decreasing current density will increase tensile strength of the deposited nickel. | Uniformity across a 4" wafer is around 5% for the standard processes (the edge being slightly thicker than the center of the sample).
