Claim:
1. A method for processing a substrate in a substrate processing system, comprising: a) flowing reactant gases into a process chamber including a substrate; b) supplying, to the process chamber, a first power level sufficient to promote rearrangement of molecules adsorbed from the reactant gases onto a surface of the substrate, wherein the first power level is supplied in a first predetermined period where (i) the reactant gases are flowing into the process chamber and (ii) a second power level is not supplied to the process chamber; c) waiting a second predetermined period subsequent to flowing the reactant gases and supplying the first power level and prior to supplying the second power level to the process chamber; d) after the second predetermined period, performing plasma-enhanced, pulsed chemical vapor deposition of film on the substrate by supplying one or more precursors while supplying the second power level to the process chamber for a third predetermined period, wherein performing the pulsed chemical vapor deposition includes providing a pulse train including a sequence of pulses supplying the one or more precursors while the second power level is continuously supplied, and wherein the second power level is greater than the first power level; and e) removing reactants from the process chamber, wherein the first power level is supplied from (b) to (e).
