Claim 0:
1. A pretreatment process for metal nitride nucleation on the surface of a microelectronic device substrate in a reaction zone, which comprises:
I. introducing compounds chosen from A, B, and C into a reaction zone under pulsed vapor deposition conditions, wherein said pulsed vapor deposition conditions comprise a plurality of pulse sequences, wherein at least two of compounds, A, B, and C are introduced into said reaction zone, one of which is A, sequentially and in any order, each optionally followed by a purge step with an inert gas, to define a cycle of pulse sequences, wherein said plurality comprises at least three cycles, wherein A, B, and C are defined as:
A. a precursor chosen from silicon-containing halides and silicon-containing amides, wherein A is bis-t-amyl ethylene silylene;
B. a metal precursor, wherein said metal is chosen from titanium, tantalum, molybdenum, tungsten, and niobium; and
C. a nitrogen-containing reducing gas, wherein said nitrogen-containing reducing gas is introduced into said reaction zone once or twice per cycle of each pulse sequence.
