Methods for selective deposition are provided. Material is selectively deposited on a first surface of a substrate relative to a second surface of a different material composition. An inhibitor, such as a polyimide layer, is selectively formed from vapor phase reactants on the first surface relative to the second surface. A layer of interest is selectively deposited from vapor phase reactants on the second surface relative to the first surface. The first surface can be metallic while the second surface is dielectric. Accordingly, material, such as a dielectric transition metal oxides and nitrides, can be selectively deposited on metallic surfaces relative dielectric surfaces using techniques described herein.

Selective passivation and selective deposition

The present disclosure relates to methods and apparatuses for the manufacture of semiconductor devices. More particularly, the disclosure relates to methods and apparatuses for depositing an organic layer selectively on a substrate comprising at least two different surfaces. The process comprises providing a substrate in a reaction chamber, providing a first vapor-phase precursor in the reaction chamber, and providing a second vapor-phase precursor in the reaction chamber. In the method, the first and second vapor-phase precursors form the organic material selectively on the first surface relative to the second surface, and the first vapor-phase precursor comprises a diamine compound comprising at least five carbon atoms and the amine groups being attached to non-adjacent carbon atoms.

Selective deposition of organic material

The disclosure relates to the manufacture of semiconductor devices, especially to methods and processing assemblies for forming a patterned structure on a substrate. The methods comprise providing the substrate comprising a first structure into a reaction chamber, wherein a surface of the first structure comprises a first material and the substrate comprises a second material, and selectively depositing a conformal passivation layer on the first material relative to the second material to cover the first structure, and selectively depositing an etch-stop layer on the second material relative to the passivation layer. In some embodiments, a multiple patterning or a tone reversal of a pattern may be performed using the methods and deposition assemblies of the disclosure.

Method and apparatus for forming a patterned structure on a substrate

Methods and vapor deposition assemblies of selectively depositing material comprising silicon and oxygen on a first surface of a substrate relative to a second surface of the substrate by a cyclic deposition process are disclosed. The methods comprise providing a substrate into a reaction chamber, providing a metal or metalloid catalyst into the reaction chamber in a vapor phase, providing a silicon precursor comprising an alkoxy silane compound into the reaction chamber in a vapor phase and providing a plasma into the reaction chamber to form a reactive species for forming a material comprising silicon and oxygen on the first surface. The methods may comprise subcycles for, for example, adjusting the proportions of material components.

Selective deposition of material comprising silicon and oxygen using plasma

Methods for cleaning a substrate are disclosed. The substrate comprises a dielectric surface and a metal surface. The methods comprise providing a cleaning agent to the reaction chamber.

Method of cleaning a surface

Methods for selective deposition, and structures thereof, are provided. Material is selectively deposited on a first surface of a substrate relative to a second surface of a different material composition. A passivation layer is selectively formed from vapor phase reactants on the first surface while leaving the second surface without the passivation layer. A layer of interest is selectively deposited from vapor phase reactants on the second surface relative to the passivation layer. The first surface can be metallic while the second surface is dielectric, or the second surface is dielectric while the second surface is metallic. Accordingly, material, such as a dielectric, can be selectively deposited on either metallic or dielectric surfaces relative to the other type of surface using techniques described herein. Techniques and resultant structures are also disclosed for control of positioning and shape of layer edges relative to boundaries between underlying disparate materials.

The current disclosure generally relates to the manufacture of semiconductor devices. Specifically, the disclosure relates to methods of depositing a layer on a substrate comprising a recess. The method comprises providing the substrate comprising a recess in a reaction chamber, depositing inhibition material on the substrate to fill the recess with inhibition material, removing the inhibition material from the substrate for exposing a deposition area and depositing a layer on the deposition area by a vapor deposition process. A vapor deposition assembly for performing the method is also disclosed.

Toposelective vapor deposition using an inhibitor

Methods for selective deposition of metal oxide films on metal or metallic surfaces relative to oxide surfaces are provided. An oxide surface of a substrate may be selectively passivated relative to the metal or metallic surface, such as by exposing the substrate to a silylating agent. A metal oxide is selectively deposited from vapor phase reactants on the metal or metallic surface relative to the passivated oxide surface.

Selective deposition of metal oxides on metal surfaces

Methods for selectively forming a target film on a substrate comprising a first dielectric surface and a second metallic surface are disclosed. The methods may include: contacting the substrate with a plasma generated from a hydrogen containing gas, selectively forming a passivation film from vapor phase reactants on the first dielectric surface while leaving the second metallic surface free from the passivation film, and selectively depositing the target film from vapor phase reactants on the second metallic surface relative to the passivation film.

Methods for selectively forming a target film on a substrate comprising a first dielectric surface and a second metallic surface

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.

Selective deposition of silicon oxide on dielectric surfaces relative to metal surfaces

Methods for selective deposition of silicon oxide films on metal or metallic surfaces relative to dielectric surfaces are provided. A dielectric surface of a substrate may be selectively passivated relative to a metal or metallic surface, such as by exposing the substrate to a silylating agent. Silicon oxide is then selectively deposited on the metal or metallic surface relative to the passivated oxide surface by contacting the metal surface with a metal catalyst and a silicon precursor comprising a silanol.
