Abstract:
1. A method for processing a substrate in a substrate processing system, comprising: a) flowing reactant gases into a process chamber; b) supplying, from a first power source, plasma having a first power level; c) dosing the process chamber with precursor, wherein the first power level is sufficient to enhance adsorption of the precursor on a surface of the substrate, and wherein the first power level is insufficient to decompose the precursor that is adsorbed; d) after a first predetermined period, removing a portion of the precursor that does not adsorb onto the substrate from the process chamber while the plasma having the first power level is still being supplied from the first power source; e) activating the precursor that is adsorbed using plasma having a second power level supplied from a second power source while the plasma having the first power level is still being supplied from the first power source, wherein the second power level is greater than the first power level and is sufficient to decompose the precursor that is adsorbed; and f) removing reactants from the process chamber while the plasma having the first power level is still being supplied from the first power source, wherein the first power level is supplied from the first power source from (b) to (f) such that supplying the plasma having the first power level from the first power source occurs at a same time as supplying the plasma having the second power level from the second power source.
