Abstract
Exemplary methods of electroplating may include delivering a current from a power supply through a plating bath of an electroplating chamber for a first period of time. The current delivered may be or include a pulsed current at a duty cycle of less than or about 50%. The methods may include plating a first amount of metal on a substrate within the plating bath. The substrate may define a via within the substrate. The methods may include, subsequent the first period of time, transitioning the power supply to a continuous DC current delivery for a second period of time. The methods may include plating a second amount of metal on the substrate.
