Claim Text:
1. A method of electroplating on a substrate comprising features having a width and/or depth of at least about 2 micrometers, the method comprising: (a) providing the substrate to a plating chamber, wherein the plating chamber is configured to contain an electrolyte and an anode during electroplating of metal onto the substrate, wherein the plating chamber comprises: (b) electroplating a metal onto the substrate plating surface while rotating the substrate and while flowing the electrolyte in the plating chamber in the direction of the substrate plating face and creating an impinging flow of the electrolyte in a direction substantially perpendicular to the plating face of the substrate, wherein the impinging flow of the electrolyte exits the holes of the flow shaping element and while applying a shearing force to the electrolyte flowing at the plating face of the substrate to divert the impinging flow of the electrolyte in a direction that is substantially parallel to the plating face of the substrate and to thereby create a transverse flow of the electrolyte across the center of the plating face of the substrate, wherein the shearing force is applied using the flow diverter that is configured to divert the impinging electrolyte flow into the transverse electrolyte flow flowing towards its vent region.
