Abstract:
Cleaning substrates or electroplating system components may include methods of rinsing a substrate at a semiconductor plating chamber. The methods may include moving a head from a plating bath to a first position. The head may include a substrate coupled with the head. The methods may include rotating the head for a first period of time to sling bath fluid back into the plating bath. A residual amount of bath fluid may remain. The methods may include delivering a first fluid to the substrate from a first fluid nozzle to at least partially expel the residual amount of bath fluid back into the plating bath. The methods may include moving the head to a second position. The methods may include rotating the head for a second period of time. The methods may also include delivering a second fluid across the substrate from a second fluid nozzle.
