Patent ID: 7867896

Claim:
A method for processing a substrate comprising: forming a tantalum-containing material on the substrate by a process comprising: flowing a tantalum precursor gas through a conduit and into a process chamber while maintaining the conduit at a temperature within a range from about 50° C. to about 170° C.; and exposing the substrate to at least sequential pulses of the tantalum precursor gas and a nitrogen precursor during an atomic layer deposition process to deposit a tantalum nitride material thereon; and depositing a nucleation layer on the tantalum nitride layer by a process selected from the group of an atomic layer deposition technique, a physical vapor deposition technique, a chemical vapor deposition technique, or combinations thereof; and depositing a bulk layer on the nucleation layer by a process selected from the group of an atomic layer deposition technique, a physical vapor deposition technique, a chemical vapor deposition technique, an electroplating technique, or combinations thereof.
