Abstract: Chromium containing precursors and methods of forming chromium-containing thin films are described. The chromium precursor has a chromium-diazadiene bond or cyclopentadienyl ligand and is homoleptic or heteroleptic. A suitable reactant is used to provide one of a metallic chromium film or a film comprising one or more of an oxide, nitride, carbide, boride and/or silicide. Methods of forming ternary materials comprising chromium with two or more of oxygen, nitrogen, carbon, boron, silicon, titanium, ruthenium and/or tungsten are also described. Methods of filling gaps in a substrate with a chromium-containing film are also described.

Abstract: Methods of improved selectively for SAM-based selective depositions are described. Some of the methods include forming a SAM on a second surface and a carbonized layer on the first surface. The substrate is exposed to an oxygenating agent to remove the carbonized layer from the first surface, and a film is deposited on the first surface over the protected second surface. Some of the methods include overdosing a SAM molecule to form a SAM layer and SAM agglomerates, depositing a film, removing the agglomerates, reforming the SAM layer and redepositing the film.

Abstract: 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.

Abstract: Methods for depositing protective coatings on aerospace components are provided and include sequentially exposing the aerospace component to a chromium precursor and a reactant to form a chromium-containing layer on a surface the aerospace component by an atomic layer deposition process. The chromium-containing layer contains metallic chromium, chromium oxide, chromium nitride, chromium carbide, chromium silicide, or any combination thereof.

Abstract: Methods for depositing film comprising exposing a substrate surface to an organic-based poisoning agent to preferentially inhibit film growth at the top of a feature relative to the bottom of the feature and depositing a film. The substrate can be exposed to the poisoning agent any number of times to promote bottom-up growth of the film in the feature.

Abstract: Using the systems and methods discussed herein, CMAS corrosion is inhibited via CMAS interception in an engine environment and/or is prevented or reduced by the formation of a metal oxide protective coating on a hot engine section component. The CMAS interception can occur while the engine is in operation in flight or in a testing or quality control environment. The metal oxide protective coating can be applied over other coatings, including Gd-zirconates (GZO) or yttria-stabilized zirconia (YSZ). The metal oxide protective coating is applied at original equipment manufacturers (OEM) and can also be applied in-situ using a gas injection system during engine use in-flight or during maintenance or quality testing. The metal oxide protective coating contains a rare earth element, aluminum, zirconium, chromium, or combinations thereof, and is from 1 nm to 3 microns in thickness.
