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 35):
The method of  claim 29 , wherein the electroplating comprises rotating the semiconductor substrate bidirectionally.
