Abstract: An apparatus for electroplating a metal on a semiconductor substrate with high control over plated thickness on a die-level includes an ionically resistive ionically permeable element (e.g., a plate with channels), where the element allows for flow of ionic current through the element towards the substrate during electroplating, where the element includes a plurality of regions, each region having a pattern of varied local resistance, and where the pattern of varied local resistance repeats in at least two regions.

Abstract: Various embodiments described herein relate to methods and apparatus for electroplating material onto a semiconductor substrate. In some cases, one or more membrane may be provided in contact with an ionically resistive element to minimize the degree to which electrolyte passes backwards from a cross flow manifold, through the ionically resistive element, and into an ionically resistive element manifold during electroplating. The membrane may be designed to route electrolyte in a desired manner in some embodiments. In these or other cases, one or more baffles may be provided in the ionically resistive element manifold to reduce the degree to which electrolyte is able to bypass the cross flow manifold by flowing back through the ionically resistive element and across the electroplating cell within the ionically resistive element manifold. These techniques can be used to improve the uniformity of electroplating results.

Abstract: An active (consumable) anode includes, in one aspect, a generally annular body and a protrusion used for connecting the anode to the power supply, where the protrusion extends outward from the generally annular body of the anode. The compositions of the generally annular body and of the protrusion are the same, and, in some embodiments, the anode is a one-piece anode that does not include any welding seams. Such structure results in reduced voltage fluctuations during plating and in improved control over plating uniformity. In some embodiments, the anode is a copper anode, a cobalt anode, or a nickel anode machined from a single sheet of anode-grade metal. The provided anode can be used in an electroplating apparatus as a secondary, peripherally disposed anode, in conjunction with a more centrally located primary anode. The provided anode is configured to modulate electroplating at the edge of the substrate.

Abstract: The embodiments herein relate to methods and apparatus for electroplating one or more materials onto a substrate. In many cases the material is a metal and the substrate is a semiconductor wafer, though the embodiments are no so limited. Typically, the embodiments herein utilize a channeled plate positioned near the substrate, creating a cross flow manifold defined on the bottom by the channeled plate, on the top by the substrate, and on the sides by a cross flow confinement ring. Also typically present is an edge flow element configured to direct electrolyte into a corner formed between the substrate and substrate holder. During plating, fluid enters the cross flow manifold both upward through the channels in the channeled plate, and laterally through a cross flow side inlet positioned on one side of the cross flow confinement ring. The flow paths combine in the cross flow manifold and exit at the cross flow exit, which is positioned opposite the cross flow inlet.

Abstract: Methods and apparatus for electroplating substrates are described herein. In some cases, an ionically resistive element is positioned near the substrate, creating a cross flow manifold between the ionically resistive element and the substrate. During plating, fluid may enter the cross flow manifold upward through the channels in the ionically resistive element, and (optionally) laterally through a cross flow side inlet. The flow paths combine in the cross flow manifold and exit at the cross flow outlet, which may be positioned opposite the cross flow inlet. In some embodiments, the ionically resistive element may include two or more flow regions, where the flow through each flow region is independently controllable. In these or other embodiments, an electrolyte jet may be included to flow additional electrolyte toward the substrate at a particular radial location or locations during plating. In some embodiments, the ionically resistive element may be omitted.

Also disclosed herein are apparatuses for electroplating which may include one or more seals for substantially sealing a subset of the pores in a fluidically-permeable plate whose sealing configuration affects a rate of electroplating in an edge region of the substrate.
