Methods of selectively inhibiting deposition of silicon-containing films deposited by atomic layer deposition are provided. Selective inhibition involves exposure of an adsorbed layer of a silicon-containing precursor to a hydrogen-containing inhibitor, and in some instances, prior to exposure of the adsorbed layer to a second reactant. Exposure to a hydrogen-containing inhibitor may be performed with a plasma, and methods are suitable for selective inhibition in thermal or plasma enhanced atomic layer deposition of silicon-containing films. |
