A method includes forming a first layer and a second layer on a substrate, forming a passivation layer on a surface of the first layer without forming the passivation layer on a surface of the second layer by exposing the first layer and the second layer to a benzyl compound, and after forming the passivation layer on the first layer, performing at least one of: depositing a third layer on the second layer, or etching the second layer.

Benzyl compound passivation for selective deposition and selective etch protection

Embodiments generally relate to methods for depositing silicon-phosphorous materials, and more specifically, relate to using silicon-phosphorous compounds in vapor deposition processes (e.g., epitaxy, CVD, or ALD) to deposit silicon-phosphorous materials. In one or more embodiments, a method for forming a silicon-phosphorous material on a substrate is provided and includes exposing the substrate to a deposition gas containing one or more silicon-phosphorous compounds during a deposition process and depositing a film containing the silicon-phosphorous material on the substrate. The silicon-phosphorous compound has the chemical formula [(RHSi)—(RHSi)]PHR', where each instance of R and each instance of R′ are independently an alkyl or a halogen, n is 0, 1, or 2; v is 0, 1, 2, or 3; w is 0, 1, or 2; x is 1, 2, or 3; y is 0, 1, or 2; z is 0, 1, or 2, and where x+y+z=3.

Method for forming silicon-phosphorous materials

Methods and apparatus for processing a substrate are provided herein. For example, a method of processing a substrate comprises a) removing oxide from a metal layer disposed in a dielectric layer on the substrate disposed in a processing chamber, b) selectively depositing a self-assembled monolayer (SAM) on the metal layer using atomic layer deposition, c) depositing a precursor while supplying water to form one of an aluminum oxide (AlO) layer on the dielectric layer or a low-k dielectric layer on the dielectric layer, d) supplying at least one of hydrogen (H) or ammonia (NH) to remove the self-assembled monolayer (SAM), and e) depositing one of a silicon oxycarbonitride (SiOCN) layer or a silicon nitride (SiN) layer atop the metal layer and the one of the aluminum oxide (AlO) layer on the dielectric layer or the low-k dielectric layer on the dielectric layer.

Methods and apparatus for selective etch stop capping and selective via open for fully landed via on underlying metal

A method includes performing a dry etch process to remove a portion of a first layer disposed on a second layer of a stack of alternating layers. The first layer includes a first material and the second layer includes a second material different from the first material, and the dry etch process forms a passivation layer including a byproduct on surfaces of the second material. A amount of first material of the portion of the first layer remains after performing the dry etch process, The method further includes introducing a halide gas to enhance the passivation layer on the surfaces of the second material.

Enhanced etch selectivity using halides

Disclosed is a coated chamber component comprising a body having a reduced metal surface such that the reduced metal surface has less metal oxide as compared to an amount of metal oxide on a metal surface that has not been reduced. The metal surface may be reduced by pulsing a reducing alcohol thereon. The reduced metal surface may be coated with a corrosion resistant film that may be deposited onto the reduced metal surface by a dry atomic layer deposition process.

Corrosion resistant film on a chamber component and methods of depositing thereof

Embodiments disclosed herein include methods of depositing a metal oxo photoresist using dry deposition processes. In an embodiment, the method comprises forming a first metal oxo film on the substrate with a first vapor phase process including a first metal precursor vapor and a first oxidant vapor, and forming a second metal oxo film over the first metal oxo film with a second vapor phase process including a second metal precursor vapor and a second oxidant vapor.

Deposition of semiconductor integration films

Embodiments of this disclosure provide methods for etching oxide materials. Some embodiments of this disclosure provide methods which selectively etch oxide materials over other materials. In some embodiments, the methods of this disclosure are performed by atomic layer etching (ALE). In some embodiments, the methods of this disclosure are performed within a processing chamber comprising a nickel chamber material.

Etching of metal oxides using fluorine and metal halides

Methods of depositing a film selectively onto a first substrate surface relative to a second substrate surface are described. The methods include exposing the substrate surfaces to a blocking compound to selectively form a blocking layer on at least a portion of the first surface over the second surface. The substrate is sequentially exposed to a metal precursor with a kinetic diameter in excess of 21 angstroms and a reactant to selectively form a metal-containing layer on the second surface over the blocking layer or the first surface. The relatively larger metal precursors of some embodiments allow for the use of blocking layers with gaps or voids without the loss of selectivity.

Methods of selective atomic layer deposition

Organometallic precursors and methods of depositing high purity metal films are discussed. Some embodiments utilize a method comprising exposing a substrate surface to an organometallic precursor comprising one or more of molybdenum (Mo), tungsten (W), osmium (Os), technetium (Tc), manganese (Mn), rhenium (Re) or ruthenium (Ru), and an iodine-containing reactant comprising a species having a formula RI, where R is one or more of a C-Calkyl, C-Ccycloalkyl, C-Calkenyl, or C-Calkynyl group, I is an iodine group and x is in a range of 1 to 4 to form a carbon-less iodine-containing metal film. Some embodiments advantageously provide methods of forming metal films having low carbon content (e.g., having greater than or equal to 95% metal species on an atomic basis), without using an oxidizing agent or a reductant.

Method of depositing metal films

Methods of selectively depositing blocking layers on conductive surfaces over dielectric surfaces are described. In some embodiments, a 4-8 membered substituted heterocycle is exposed to a substrate to selectively form a blocking layer. In some embodiments, a layer is selectively deposited on the dielectric surface after the blocking layer is formed. In some embodiments, the blocking layer is removed.

Methods for depositing blocking layers on conductive surfaces

Some embodiments include a method of depositing a photoresist onto a substrate in a processing chamber. In an embodiment, the method comprises flowing an oxidant into the processing chamber through a first path in a showerhead, and flowing an organometallic into the processing chamber through a second path in the showerhead. In an embodiment, the first path is isolated from the second path so that the oxidant and the organometallic do not mix within the showerhead. In an embodiment, the method further comprises that the oxidant and the organometallic react in the processing chamber to deposit the photoresist on the substrate.

Photoresist deposition using independent multichannel showerhead

Embodiments of the disclosure relate to methods for selectively removing metal material from the top surface and sidewalls of a feature. The metal material which is covered by a flowable polymer material remains unaffected. In some embodiments, the metal material is formed by physical vapor deposition resulting in a relatively thin sidewall thickness. Any metal material remaining on the sidewall after removal of the metal material from the top surface may be etched by an additional etch process. The resulting metal layer at the bottom of the feature facilitates selective metal gapfill of the feature.

Selective metal removal with flowable polymer

Described herein is a method for selectively cleaning and/or etching a sample. The method includes selectively forming a film in a trench of a substrate such that the trench may be selectively etched. A polymer film is deposited on the bottom surface of the trench without being deposited on the side wall. A second film is selectively formed in the trench without forming the second film on the polymer film. The polymer is then removed from the bottom surface of the trench and then etching is performed on the bottom surface of the trench using an etch chemistry, wherein the second film protects the side wall from being etched.

Selective etch of a substrate

Methods of enhancing selective deposition are described. In some embodiments, a blocking layer is deposited on a metal surface before deposition of a dielectric. In some embodiments, a metal surface is functionalized to enhance or decrease its reactivity.

Methods for depositing blocking layers on metal surfaces

Transition metal dichalcogenide films and methods for depositing transition metal dichalcogenide films on a substrate are described. Methods for converting transition metal oxide films to transition metal dichalcogenide films are also described. The substrate is exposed to a precursor and a chalcogenide reactant to form the transition metal dichalcogenide film. The exposures can be sequential or simultaneous.
