Abstract
Apparatus and methods for uniform metal plating onto a semiconductor wafer, such as GaAs wafer, are disclosed. One such apparatus can include an anode and a showerhead body. The anode can include an anode post and a showerhead anode plate. The showerhead anode plate can include holes sized to dispense a particular plating solution, such as plating solution that includes gold, onto a wafer. The showerhead body can be coupled to the anode post and the showerhead anode plate. The showerhead body can be configured to create a seal sufficient to substantially prevent a reduction of pressure in the plating solution flowing from the anode post to holes of the showerhead anode plate.
