Claim 4:
5. A process for metal nitride nucleation on the surface of a microelectronic device substrate in a reaction zone, the process comprising the process of claim 1, further comprising:
introducing into said reaction zone a second cycle of pulse sequences comprising introducing compounds D and E into said reaction zone, in either order, each optionally followed by purging with an inert gas:
D. a metal precursor, wherein said metal is chosen from titanium, tantalum, molybdenum, tungsten, and niobium; and
E. a nitrogen-containing reducing gas; and
repeating said second cycle of pulse sequences for a sufficient number of iterations to establish a metal nitride nucleation on a substrate to afford a coverage representing less than about 1% of void areas in a film having a thickness of about 10 Å to about 15 Å.
