Patent number: 10577712Abstract: 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.Type: GrantFiled: January 29, 2019Date of Patent: March 3, 2020Assignee: APPLIED MATERIALS, INC.Inventors: Gregory J.
