  • Publication number: 20210351031
    Abstract: Vapor deposition processes are provided in which a material is selectively deposited on a first surface of a substrate relative to a second organic surface. In some embodiments a substrate comprising a first surface, such as a metal, semi-metal or oxidized metal or semi-metal is contacted with a first vapor phase hydrophobic reactant and a second vapor phase reactant such that the material is deposited selectively on the first surface relative to the second organic surface. The second organic surface may comprise, for example, a self-assembled monolayer, a directed self-assembled layer, or a polymer, such as a polyimide, polyamide, polyurea or polystyrene. The material that is deposited may be, for example, a metal or metallic material. In some embodiments the material is a metal oxide, such as ZrO2 or HfO2. In some embodiments the vapor deposition process is a cyclic chemical vapor deposition (CVD) process or an atomic layer deposition (ALD) process.

  • Publication number: 20210301392
    Abstract: Methods for selective deposition of silicon oxide films on dielectric surfaces relative to metal surfaces are provided. A metal surface of a substrate may be selectively passivated relative to the dielectric surface, such as with a polyimide layer or thiol SAM. Silicon oxide is selectively deposited on the dielectric surface relative to the passivated metal surface by contacting the dielectric surface with a metal catalyst and a silicon precursor comprising a silanol.

  • Publication number: 20210301391
    Abstract: In some embodiments, methods are provided for simultaneously and selectively depositing a first material on a first surface of a substrate and a second, different material on a second, different surface of the same substrate using the same reaction chemistries. For example, a first material may be selectively deposited on a metal surface while a second material is simultaneously and selectively deposited on an adjacent dielectric surface. The first material and the second material have different material properties, such as different etch rates.

  • Patent number: 10991573
    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: 10964534
    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.

  • Patent number: 10900120
    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.
