    Abstract: Systems and methods for electroplating are described. The electroplating system may include a vessel configured to hold a first portion of a liquid electrolyte. The system may also include a substrate holder configured for holding a substrate in the vessel. The system may further include a first reservoir in fluid communication with the vessel. In addition, the system may include a second reservoir in fluid communication with the vessel. Furthermore, the system may include a first mechanism configured to expel a second portion of the liquid electrolyte from the first reservoir into the vessel. The system may also include a second mechanism configured to take in a third potion of the liquid electrolyte from the vessel into the second reservoir when the second portion of the liquid electrolyte is expelled from the first reservoir. Methods may include oscillating flow of the electrolyte within the vessel.

    Abstract: Exemplary methods of producing a semiconductor substrate may include characterizing a substrate pattern to identify a zonal distribution of a plurality of vias and a height and a radius of each via of the plurality of vias. The methods may include determining a fill rate for each via within the zonal distribution of the plurality of vias. The methods may include modifying a die pattern to adjust via fill rates between two zones of vias. The methods may also include producing a substrate according to the die pattern.

    Abstract: An electroplating processor has a head including a wafer holder, with the head movable to position a wafer in the wafer holder into a vessel holding a first electrolyte and having one or more anodes. A thief electrode assembly may be positioned adjacent to a lower end of the vessel, or below the anode. A thief current channel extends from the thief electrode assembly to a virtual thief position adjacent to the wafer holder. A thief electrode in the thief electrode assembly is positioned within a second electrolyte which is separated from the first electrolyte by a membrane. Alternatively, two membranes may be used with an isolation solution between them. The processor avoids plating metal onto the thief electrode, even when processing redistribution layer and wafer level packaging wafers having high amp-minute electroplating characteristics.

    Abstract: Electroplating apparatus agitates electrolyte to provide high velocity fluid flows at the surface of a wafer. The apparatus includes a paddle which provides uniform high mass transfer over the entire wafer, even with a relatively large gap between the paddle and the wafer. Consequently, the processor may have an electric field shield positioned between the paddle and the wafer for effective shielding at the edges of the wafer. The influence of the paddle on the electric field across the wafer is reduced as the paddle is spaced relatively farther from the wafer.

    Abstract: An electroplating apparatus has a vessel for holding electrolyte. A head has a rotor including a contact ring for holding a wafer having a notch. The contact ring includes a perimeter voltage ring having perimeter contact fingers for contacting the wafer around the perimeter of the wafer, except at the notch. The contact ring also has a notch contact segment having one or more notch contact fingers for contacting the wafer at the notch. The perimeter voltage ring is insulated from the notch contact segment. A negative voltage source is connected to the perimeter voltage ring, and a positive voltage source connected to the notch contact segment. The positive voltage applied at the notch reduces the current crowding effect at the notch. The wafer is plated with a film having more uniform thickness.

    Abstract: An electrochemical processor may include a head having a rotor configured to hold a workpiece, with the head moveable to position the rotor in a vessel. Inner and outer anodes are in inner and outer anolyte chambers within the vessel. An upper cup in the vessel, has a curved upper surface and inner and outer catholyte chambers. A current thief is located adjacent to the curved upper surface. Annular slots in the curved upper curved surface connect into passageways, such as tubes, leading into the outer catholyte chamber. Membranes may separate the inner and outer anolyte chambers from the inner and outer catholyte chambers, respectively.
