Abstract:
1. A method for forming a tantalum-containing material on a substrate, comprising: heating a substrate to a deposition temperature within a process chamber; heating a tantalum precursor within an ampoule to a predetermined temperature in a range from about 65° C. to about 150° C. to form a heated tantalum precursor; flowing the heated tantalum precursor into a vaporizer to form a tantalum-containing gas; flowing the tantalum-containing gas through a conduit and into the process chamber while maintaining the conduit at a temperature in a range from about 65° C. to about 150° C.; and exposing the substrate to at least sequential pulses of the tantalum-containing gas and a nitrogen precursor gas during an ALD process to deposit a tantalum nitride material thereon.
