  • Multi-compartment electrochemical replenishment cell
    Patent number: 11697887
    Abstract: Electroplating systems may include an electroplating chamber. The systems may also include a replenish assembly fluidly coupled with the electroplating chamber. The replenish assembly may include a first compartment housing anode material. The first compartment may include a first compartment section in which the anode material is housed and a second compartment section separated from the first compartment section by a divider. The replenish assembly may include a second compartment fluidly coupled with the electroplating chamber and electrically coupled with the first compartment. The replenish assembly may also include a third compartment electrically coupled with the second compartment, the third compartment including an inert cathode.
    Type: Grant

  • ELECTROPLATING SYSTEM
    Publication number: 20230167573
    Abstract: An electroplating system has a vessel assembly holding an electrolyte. A weir thief electrode assembly in the vessel assembly includes a plenum inside of a weir frame. The plenum divided into at least a first, a second and a third virtual thief electrode segment. A plurality of spaced apart openings through the weir frame lead out of the plenum. A weir ring is attached to the weir frame and guides flow of current during electroplating. The electroplating system provides process determined radial and circumferential current density control and does not require changing hardware components during set up.
