Abstract:
An apparatus for electroplating metal on a semiconductor substrate with improved azimuthal uniformity includes in one aspect: a plating chamber configured to contain an electrolyte and an anode; a substrate holder configured to hold the semiconductor substrate; an ionically resistive ionically permeable element (“the element”) configured to be positioned proximate the substrate; and a shield configured for providing azimuthally asymmetrical shielding and positioned between the substrate holder and the element such that the closest distance between the substrate-facing surface of the shield and the working surface of the substrate is less than 2 mm. In some embodiments there is an electrolyte-filled gap between the substrate-facing surface of the element and the shield during electroplating. The substrate-facing surface of the shield may be contoured such that the distance from different positions of the shield to the substrate is varied.

Claim (Index 26):
The electroplating apparatus of  claim 21 , further comprising an ionically resistive ionically permeable element comprising a substrate-facing surface and an opposing surface, wherein the element allows for flow of ionic current through the element towards the substrate during electroplating, wherein the ionically resistive ionically permeable element comprises a plurality of channels, and wherein the ionically resistive ionically permeable element is positioned such that a closest distance between the substrate-facing surface of the element and a working surface of the substrate is about 10 mm or less; and wherein the shield is positioned such that there is an electrolyte-filled gap between the shield and the ionically resistive ionically permeable element during electroplating.
