Methods for producing halosilazane comprise halogenating a hydrosilazane with a halogenating agent to produce the halosilazane, the halosilazane having a formula

(SiH.sub.a(NR.sub.2).sub.bX.sub.c).sub.(n+2)N.sub.n(SiH.sub.(2−d)X.sub.d).sub.(n−1),

wherein each a, b, c is independently 0 to 3; a+b+c=3; d is 0 to 2 and n≥1; wherein X is selected from a halogen atom selected from F, Cl, Br or I; each R is selected from H, a C.sub.1-C.sub.6 linear or branched, saturated or unsaturated hydrocarbyl group, or a silyl group [SiR′.sub.3]; further wherein each R′ of the [SiR′.sub.3] is independently selected from H, a halogen atom selected from F, Cl, Br or I, a C.sub.1-C.sub.4 saturated or unsaturated hydrocarbyl group, a C.sub.1-C.sub.4 saturated or unsaturated alkoxy group, or an amino group [—NR.sup.1R.sup.2] with each R.sup.1 and R.sup.2 being further selected from H or a C.sub.1-C.sub.6 linear or branched, saturated or unsaturated hydrocarbyl group, provided that when c=0, d≠0; or d=0, c≠0.

A method for forming a silicon nitride film that may be carbon doped via a plasma ALD process includes introducing a substrate into a reactor, which is heated to up to about 600° C. At least one silicon precursor as defined herein and having one or two Si—C—Si linkages is introduced to form a chemisorbed film on the substrate. The reactor is then purged of any unconsumed precursors and/or reaction by-products with a suitable inert gas. A plasma comprising nitrogen is introduced into the reactor to react with the chemisorbed film to form the silicon nitride film that may be carbon doped. The reactor is again purged of any reaction by-products with a suitable inert gas. The steps are repeated as necessary to bring the deposited silicon nitride film that may be carbon doped to a predetermined thickness.

There is included (a) loading a substrate where a conductive metal-element-containing film is exposed on a surface of the substrate into a process chamber under a first temperature; (b) supplying a reducing gas to the substrate while raising a temperature of the substrate to a second temperature higher than the first temperature in the process chamber; (c) forming a first film on the metal-element-containing film, by supplying a first process gas, which does not include an oxidizing gas, to the substrate under the second temperature in the process chamber; and (d) forming a second film on the first film such that the second film is thicker than the first film, by supplying a second process gas, which includes an oxidizing gas, to the substrate under a third temperature higher than the first temperature in the process chamber.

Disclosed is a degradable film (1) in which a barrier layer (3) is disposed on a surface of a water-soluble polymer layer (2). The water-soluble polymer layer (2) is made of a water-soluble polymer such as polyvinyl alcohol or polyvinyl pyrrolidone. The barrier layer (3) is made of silicon oxide or silicon oxynitride. The barrier layer (3) is formed on the water-soluble polymer layer (2) by a CVD process with the supply of a raw material gas containing a precursor of a substance that forms the barrier layer (3), an ozone gas with an oxygen concentration of 20 vol % or higher and an unsaturated hydrocarbon gas to the water-soluble polymer layer (2).

A doped or undoped silicon carbide (SiC.sub.xO.sub.yN.sub.z) film can be deposited in one or more features of a substrate for gapfill. After a first thickness of the doped or undoped silicon carbide film is deposited in the one or more features, the doped or undoped silicon carbide film is exposed to a remote hydrogen plasma under conditions that cause a size of an opening near a top surface of each of the one or more features to increase, where the conditions can be controlled by controlling treatment time, treatment frequency, treatment power, and/or remote plasma gas composition. Operations of depositing additional thicknesses of silicon carbide film and performing a remote hydrogen plasma treatment are repeated to at least substantially fill the one or more features. Various time intervals between deposition and plasma treatment may be added to modulate gapfill performance.

Provided is a plasma enhanced atomic layer deposition (PEALD) process for depositing etch-resistant SiOCN films. These films provide improved growth rate, improved step coverage and excellent etch resistance to wet etchants and post-deposition plasma treatments containing O.sub.2 and NH.sub.3 co-reactants. This PEALD process relies on one or more precursors reacting in tandem with the plasma exposure to deposit the etch-resistant thin-films of SiOCN. The films display excellent resistance to wet etching with dilute aqueous HF solutions, both after deposition and after post-deposition plasma treatment(s). Accordingly, these films are expected to display excellent stability towards post-deposition fabrication steps utilized during device manufacturing and build.

A process is provided for depositing a substantially amorphous titanium oxynitride thin film that can be used, for example, in integrated circuit fabrication, such as in forming spacers in a pitch multiplication process. The process comprises contacting the substrate with a titanium reactant and removing excess titanium reactant and reaction byproducts, if any. The substrate is then contacted with a second reactant which comprises reactive species generated by plasma, wherein one of the reactive species comprises nitrogen. The second reactant and reaction byproducts, if any, are removed. The contacting and removing steps are repeated until a titanium oxynitride thin film of desired thickness has been formed.

Provided herein are low resistance metallization stack structures for logic and memory applications and related methods of fabrication. In some embodiments, thin metal oxynitride or metal nitride nucleation layers are deposited followed by deposition of a pure metal conductor. The nucleation layer is amorphous, which templates large pure metal film grain growth and reduced resistivity. Further, certain embodiments of the methods described below convert most or all of the metal oxynitride nucleation layer to a pure metal layer, further lowering the resistivity.

Included are the steps of: forming a laminated body (7) by disposing a resin layer (12), an inorganic layer (3) having mean stress (Px) of 0 (zero) or having tensile stress, a TFT layer (4), an OLED element layer (5), and a sealing layer (6) in this order on an upper side of a supporting substrate (50); and separating the supporting substrate (50) from the laminated body (7).
