Abstract: A method for depositing a metal on a substrate is provided. The metal is deposited by sequentially applying a electrodeposition pulse followed by an electrodissolution pulse to the substrate. After each electrodissolution pulse an before the next electrodeposition pulse there is provided at least one time interval of zero electrical voltage or current, also known as an “off-time”, between the pulses. The first two electrodeposition pulses should preferably have the same time durations. Thereafter, the time durations of subsequent electrodeposition pulses are gradually decreased to provide a void-free and seam-free deposition of metal in high aspect ratio features.

Abstract: A system for supplying processing fluid to a substrate processing chamber. The system consists of a number of fluid storages each which stores a separate processing fluid; at least two fluid conduits along which processing fluid flows from the fluid storages to the processing apparatus; and a fluid inlet which connects the fluid conduits to the processing chamber. The inlet has a separate fluid passage, corresponding to each of the fluid conduits, formed along it. Each fluid passage opens at or near an inner surface of a wall of the chamber into a mixing zone, so that fluid moving along one fluid passage is prevented from mixing with fluid moving along any other passage until reaching the mixing zone. Typically at least two of the fluid passages are vertically displaced from one another to, at least partially, define upper and lower fluid flow paths.

The second conductive material may comprise nickel, tin, or combinations thereof. The substrate may then be further processed by electroplating a third conductive material on the second conductive material and/or annealing the substrate.
