Patent ID: 6869515

Claim:
A method for electrochemical deposition (ECD) on a substrate with a metal or alloy, the substrate comprising an electrically conductive surface, the method comprising steps of: immersing the substrate in an electrolyte contained in an electrochemical deposition (ECD) cell, the ECD cell comprising at least one anode and a cathode, wherein the cathode comprises at least a portion of the conductive surface of the substrate, and wherein the electrolyte comprises plating metallic ions and at least one inhibitor additive, said plating metallic ions having concentration; providing substantially uniform agitation of the electrolyte across the electrically conductive surface of the substrate, the agitation having an agitation strength; and applying current between the at least one anode and the cathode to generate an electroplating current density; wherein the agitation strength and the concentration of the plating metallic ions have values adequate to provide that the electroplating current density has a limiting current density of about an order of magnitude higher than 55 mA/cm 2 .
