  • Publication number: 20190341245
    Abstract: Methods and systems for selectively depositing dielectric films on a first surface of a substrate relative to a passivation layer previously deposited on a second surface are provided. The methods can include at least one cyclical deposition process used to deposit material on the first surface while the passivation layer is removed, thereby preventing deposition over the passivation layer.

  • Publication number: 20190267231
    Abstract: Methods of producing metal-containing thin films with low impurity contents on a substrate by atomic layer deposition (ALD) are provided. The methods preferably comprise contacting a substrate with alternating and sequential pulses of a metal source chemical, a second source chemical and a deposition enhancing agent. The deposition enhancing agent is preferably selected from the group consisting of hydrocarbons, hydrogen, hydrogen plasma, hydrogen radicals, silanes, germanium compounds, nitrogen compounds, and boron compounds. In some embodiments, the deposition-enhancing agent reacts with halide contaminants in the growing thin film, improving film properties.

  • Publication number: 20190172701
    Abstract: 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/H2 plasma. 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.

  • Patent number: 10204790
    Abstract: In accordance with some embodiments herein, methods for deposition of thin films are provided. In some embodiments, thin film deposition is performed in a plurality of stations, 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.

  • Publication number: 20190017170
    Abstract: Passivation layers to inhibit vapor deposition can be used on reactor surfaces to minimize deposits while depositing on a substrate housed therein, or on particular substrate surfaces, such as metallic surfaces on semiconductor substrates to facilitate selective deposition on adjacent dielectric surfaces. Passivation agents that are smaller than typical self-assembled monolayer precursors can have hydrophobic or non-reactive ends and facilitate more dense passivation layers more quickly than self-assembled monolayers, particularly over complex three-dimensional structures.

  • Publication number: 20180350587
    Abstract: 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.
