Abstract: Apparatus and methods for electroplating metal onto substrates are disclosed. The electroplating apparatus comprise an electroplating cell and at least one oxidization device. The electroplating cell comprises a cathode chamber and an anode chamber separated by a porous barrier that allows metal cations to pass through but prevents organic particles from crossing. The oxidation device (ODD) is configured to oxidize cations of the metal to be electroplated onto the substrate, which cations are present in the anolyte during electroplating. In some embodiments, the ODD is implemented as a carbon anode that removes Cu(I) from the anolyte electrochemically. In other embodiments, the ODD is implemented as an oxygenation device (OGD) or an impressed current cathodic protection anode (ICCP anode), both of which increase oxygen concentration in anolyte solutions. Methods for efficient electroplating are also disclosed.

Abstract: The working electrode in the flow channel of a flow-through electrolytic detection cell is preconditioned by flowing a preconditioning electroplating solution with preconditioner species through the flow channel while applying a negative potential. Flow of liquid through the flow channel is rapidly switched from preconditioning solution to a target solution containing an organic target solute to be measured. The transient response of the system resulting from exposure of the working electrode to organic target solute is detected by measuring current density during an initial transient time period. An unknown concentration of target solute is determined by comparing the transient response with one or more transient responses characteristic of known concentrations. A preferred measuring system is operable to switch flow from preconditioning solution to target solution in about 200 milliseconds or less.

Abstract: A method for electrofilling large, high aspect ratio recessed features with copper without depositing substantial amounts of copper in the field region is provided. The method allows completely filling recessed features having aspect ratios of at least about 5:1 such as at least about 10:1, and widths of at least about 1 μm in a substantially void-free manner without depositing more than 5% of copper in the field region (relative to the thickness deposited in the recessed feature). The method involves contacting the substrate having one or more large, high aspect ratio recessed features (such as a TSVs) with an electrolyte comprising copper ions and an organic dual state inhibitor (DSI) configured for inhibiting copper deposition in the field region, and electrodepositing copper under potential-controlled conditions, where the potential is controlled not exceed the critical potential of the DSI.

Abstract: Methods of electroplating metal on a substrate while controlling azimuthal uniformity, include, in one aspect, providing the substrate to the electroplating apparatus configured for rotating the substrate during electroplating, and electroplating the metal on the substrate while rotating the substrate relative to a shield such that a selected portion of the substrate at a selected azimuthal position dwells in a shielded area for a different amount of time than a second portion of the substrate having the same average arc length and the same average radial position and residing at a different angular (azimuthal) position. For example, a semiconductor wafer substrate can be rotated during electroplating slower or faster, when the selected portion of the substrate passes through the shielded area.
