Abstract: In a method of depositing a silicon oxide film using bis(diethylamino)silane (BDEAS) on a substrate in a reaction space by plasma-enhanced atomic layer deposition (PEALD), each repeating deposition cycle of PEALD includes steps of: (i) adsorbing BDEAS on the substrate placed on a susceptor having a temperature of higher than 400° C. in an atmosphere substantially suppressing thermal decomposition of BDEAS in the reaction space; and (ii) exposing the substrate on which BDEAS is adsorbed to an oxygen plasma in the atmosphere in the reaction space, thereby depositing a monolayer or sublayer of silicon oxide.

Abstract: Methods are provided herein for deposition of oxide films. Oxide films may be deposited, including selective deposition of oxide thin films on a first surface of a substrate relative to a second, different surface of the same substrate. For example, an oxide thin film such as an insulating metal oxide thin film may be selectively deposited on a first surface of a substrate relative to a second, different surface of the same substrate. The second, different surface may be an organic passivation layer.

Abstract: In accordance with some embodiments herein, apparatuses for deposition of thin films are provided. In some embodiments, a plurality of stations is provided, in which each station provides a different reactant or combination of reactants. The stations can be in gas isolation from each other so as to minimize or prevent undesired chemical vapor deposition (CVD) and/or atomic layer deposition (ALD) reactions between the different reactants or combinations of reactants.

Abstract: Processes are provided herein for deposition of organic films. Organic films can be deposited, including selective deposition on one surface of a substrate relative to a second surface of the substrate. For example, polymer films may be selectively deposited on a first metallic surface relative to a second dielectric surface. Selectivity, as measured by relative thicknesses on the different layers, of above about 50% or even about 90% is achieved. The selectively deposited organic film may be subjected to an etch process to render the process completely selective. Processes are also provided for particular organic film materials, independent of selectivity.

Abstract: A process is provided for depositing a substantially amorphous titanium oxynitride thin film that can be used, for example, in integrated circuit fabrication, such as in forming spacers in a pitch multiplication process. The process comprises contacting the substrate with a titanium reactant and removing excess titanium reactant and reaction byproducts, if any. The substrate is then contacted with a second reactant which comprises reactive species generated by plasma, wherein one of the reactive species comprises nitrogen. The second reactant and reaction byproducts, if any, are removed. The contacting and removing steps are repeated until a titanium oxynitride thin film of desired thickness has been formed.
