Patent number: 11982008Abstract: 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.Type: GrantFiled: January 24, 2023Date of Patent: May 14, 2024Assignee: APPLIED Materials, Inc.Inventors: Paul R. McHugh, Gregory J. Wilson, Kyle M. Hanson, John L. Klocke, Paul Van Valkenburg, Eric J. Bergman, Adam Marc McClure, Deepak Saagar Kalaikadal, Nolan Layne Zimmerman, Michael Windham, Mikael R.

Patent number: 11697887Abstract: 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: GrantFiled: October 23, 2020Date of Patent: July 11, 2023Assignee: Applied Materials, Inc.Inventors: Nolan L. Zimmerman, Charles Sharbono, Gregory J. Wilson, Paul R. McHugh, Paul Van Valkenburg, Deepak Saagar Kalaikadal, Kyle M. Hanson
