Methods for controlling the formation of oxygen containing thin films, such as silicon oxycarbide (SiOC) and silicon oxycarbonitride (SiOCN) thin films, on a substrate in a reaction space are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a silicon precursor that comprises oxygen and a second reactant that does not include oxygen. In some embodiments the plasma power can be selected from a range to achieve a desired step coverage or wet etch rate ratio (WERR) for films deposited on three dimensional features.

Plasma enhanced deposition processes for controlled formation of oxygen containing thin films

Methods for selectively depositing oxide thin films on a dielectric surface of a substrate relative to a metal surface are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a first precursor comprising oxygen and a species to be included in the oxide, such as a metal or silicon, and a second plasma reactant. In some embodiments the second plasma reactant comprises a plasma formed in a reactant gas that does not comprise oxygen. In some embodiments the second plasma reactant comprises plasma generated in a gas comprising hydrogen.

Selective PEALD of oxide on dielectric

Methods for depositing oxide thin films, such as metal oxide, metal silicates, silicon oxycarbide (SiOC) and silicon oxycarbonitride (SiOCN) thin films, on a substrate in a reaction space are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a first reactant that comprises oxygen and a component of the oxide, and a second reactant comprising reactive species that does not include oxygen species. In some embodiments the plasma power used to generate the reactive species can be selected from a range to achieve a desired step coverage or wet etch rate ratio (WERR) for films deposited on three dimensional features. In some embodiments oxide thin films are selectively deposited on a first surface of a substrate relative to a second surface, such as on a dielectric surface relative to a metal or metallic surface.

Plasma enhanced deposition processes for controlled formation of metal oxide thin films

Plasma enhanced atomic layer deposition (PEALD) processes for simultaneously depositing SiOC on two or more different surfaces of a substrate are provided. For example, SiOC may be deposited simultaneously on a first dielectric surface and a second metal or metallic surface. The PEALD processes can comprise two or more deposition cycles for forming SiOC on the two surfaces. The deposition cycles may comprise alternately and sequentially contacting the substrate with a first precursor comprising silicon and a second plasma reactant, such as an Ar/Hplasma. In some embodiments, a PEALD process further comprises contacting the substrate with a plasma reactant prior to beginning the deposition cycle. In some embodiments, the deposition cycle is repeated more than 500 times and a uniform SiOC film may be formed on the two different surfaces.

Uniform deposition of SiOC on dielectric and metal surfaces

A method of processing a substrate by omitting a photolithographic process is disclosed. The method includes forming at least one layer on a stepped structure having an upper surface, a lower surface, and a side surface that connects the upper surface to the lower surface, selectively densifying portions of the at least one layer respectively on the upper surface and the lower surface via asymmetric plasma application, and performing an isotropic etching process on the at least one layer. During the isotropic etching process, the portion of the at least one layer formed on the upper surface is separated from the portion of the at least one layer formed on the lower surface.

Method of processing a substrate and a device manufactured by using the method

A method of processing a substrate to enable selective doping without a photolithography process is provided. The method includes forming a diffusion barrier on the substrate having a patterned structure using plasma deposition method, removing the diffusion barrier except for part of the diffusion barrier using wet etching, forming a diffusion source layer on the patterned structure and the part of the diffusion barrier, and applying energy to the diffusion source layer.

Method of processing substrate

A semiconductor manufacturing method includes depositing a low-k dielectric layer, forming a trench in the low-k dielectric layer, forming a barrier layer in the trench, filling a metal on the barrier layer, planarizing the metal, and forming a capping layer on the planarized metal, wherein the capping layer includes at least two layers.
