Abstract
A method of depositing a material film on a substrate within a reaction chamber by a cyclical deposition process is disclosed. The method may include: contacting the substrate with a first vapor phase reactant and purging the reaction chamber with a first main purge. The method also includes: contacting the substrate with a second vapor phase reactant by two or more micro pulsing processes, wherein each micro pulsing process comprises: contacting the substrate with a micro pulse of a second vapor phase reactant; and purging the reaction chamber with a micro purge, wherein each of the micro pulses of the second vapor phase reactant provides a substantially constant concentration of the second vapor phase reactant into the reaction chamber. The method may also include; purging the reaction chamber with a second main purge. Device structures including a material film deposited by the methods of the disclosure are also disclosed.
