Abstract: A method and apparatus for removing conductive material from a microelectronic substrate is disclosed. One method includes disposing an electrolytic liquid between a conductive material of a substrate and at least one electrode, with the electrolytic liquid having about 80% water or less. The substrate can be contacted with a polishing pad material, and the conductive material can be electrically coupled to a source of varying electrical signals via the electrolytic liquid and the electrode. The method can further include applying a varying electrical signal to the conductive material, moving at least one of the polishing pad material and the substrate relative to the other, and removing at least a portion of the conductive material while the electrolytic liquid is adjacent to the conductive material. By limiting/controlling the amount of water in the electrolytic liquid, an embodiment of the method can remove the conductive material with a reduced downforce.

Abstract: In one aspect, a substrate is positioned within a deposition chamber. Gaseous precursors comprising TaF5 and at least one of H2O and O3 are fed to the deposition chamber under conditions effective to deposit a Ta2O5 comprising layer on the substrate. In one implementation, a substrate is positioned within a deposition chamber. A first species is chemisorbed onto the substrate within the chamber to form a first species monolayer from a gaseous first precursor comprising TaF5. The chemisorbed first species is contacted with a gaseous second precursor comprising at least one of H2O and O3 to react with the first species to form a monolayer comprising Ta and O. The chemisorbing and contacting are successively repeated under conditions effective to form a mass of material on the substrate comprising Ta2O5.
