Electroplating wafers having a pattern induced non-uniformity

An electroplating apparatus has a vessel for holding electrolyte. A head has a rotor including a contact ring for holding a wafer having a notch. The contact ring includes a perimeter voltage ring having perimeter contact fingers for contacting the wafer around the perimeter of the wafer, except at the notch. The contact ring also has a notch contact segment having one or more notch contact fingers for contacting the wafer at the notch. The perimeter voltage ring is insulated from the notch contact segment. A negative voltage source is connected to the perimeter voltage ring, and a positive voltage source connected to the notch contact segment. The positive voltage applied at the notch reduces the current crowding effect at the notch. The wafer is plated with a film having more uniform thickness.
