A method is provided for removing conductive material from a metal layer
deposited on a wafer having die level thickness variations on its
surface. The method includes contacting the metal layer with a
composition capable of planarizing die level thickness variations while
using a current having a current density within a range of between about
5 mA/cm.sup.2 and about 40 mA/cm.sup.2, applying a first current to the
wafer having a current density within a range of between about 5
mA/cm.sup.2 and about 20 mA/cm.sup.2 to remove a first portion of the
metal layer to thereby planarize the wafer surface, and administering a
second current to the wafer having a current density within a range of
between about 20 mA/cm.sup.2 and about 40 mA/cm.sup.2 to remove a second
portion of the metal layer and to leave a third portion of the metal
layer on the wafer having a predetermined thickness.
