Methods are provided herein for deposition of oxide films. Oxide films may be deposited, including selective deposition of oxide thin films on a first surface of a substrate relative to a second, different surface of the same substrate. For example, an oxide thin film such as an insulating metal oxide thin film may be selectively deposited on a first surface of a substrate relative to a second, different surface of the same substrate. The second, different surface may be an organic passivation layer.

A semiconductor component is disclosed. The semiconductor component can include: a semiconductor layer injected with a same type of dopant; a gate electrode formed above the semiconductor layer with a gate insulation film positioned in-between; a dielectric layer formed on the semiconductor layer at both sides of the gate electrode; and source/drain electrodes each formed on the dielectric layer.

A method includes depositing a first work-function layer and a second work-function layer in a first device region and a second device region, respectively, and depositing a first fluorine-blocking layer and a second fluorine-blocking layer in the first device region and the second device region, respectively. The first fluorine-blocking layer is over the first work-function layer, and the second fluorine-blocking layer is over the second work-function layer. The method further includes removing the second fluorine-blocking layer, and forming a first metal-filling layer over the first fluorine-blocking layer, and a second metal-filling layer over the second work-function layer.

A method of processing a substrate includes: providing a substrate having one or more mandrels comprising a mandrel material, wherein a layer of a spacer material coats horizontal surfaces and sidewalls of the one or more mandrels; and etching and completely removing the layer of the spacer material from the horizontal surfaces of the one or more mandrels and thereby exposing the mandrel material, without completely removing the spacer material residing at the sidewalls of the one or more mandrels. The etching includes exposing the substrate to a plasma formed using a mixture comprising a first gas and a polymer-forming gas, and wherein the etching comprises forming a polymer on the substrate. Polymer-forming gas may include carbon (C) and hydrogen (H).

Techniques herein provide methods for depositing spin-on metal materials for creating metal hard mask (MHM) structures without voids in the deposition. This includes effective spin-on deposition of TiOx, ZrOx, SnOx, HFOx, TaOx, et cetera. Such materials can help to provide differentiation of material etch resistivity for differentiation. By enabling spin-on metal hard mask (MHM) for use with a multi-line layer, a slit-based or self-aligned blocking strategy can be effectively used. Techniques herein include identifying a fill material to fill particular openings in a given relief pattern, modifying a surface energy value of surfaces within the opening such that a contact angle value of an interface between the fill material in liquid form and the sidewall or floor surfaces enables gap-free or void-free filling.

In some aspects, methods of forming a metal sulfide thin film are provided. According to some methods, a metal sulfide thin film is deposited on a substrate in a reaction space in a cyclical process where at least one cycle includes alternately and sequentially contacting the substrate with a first vapor-phase metal reactant and a second vapor-phase sulfur reactant. In some aspects, methods of forming a three-dimensional architecture on a substrate surface are provided. In some embodiments, the method includes forming a metal sulfide thin film on the substrate surface and forming a capping layer over the metal sulfide thin film. The substrate surface may comprise a high-mobility channel.

According to various aspects, a thermal-aware finned field-effect transistor (FinFET) may have a design that can substantially reduce hot spot temperatures and resolve other self-heating problems. More particularly, the FinFET design may use aluminum nitride (AlN) fins that can provide a main thermal exit and a source, drain, and channel formed from materials that can spread or dissipate heat, wherein AlN has a high thermal conductivity compared to silicon such that using AlN to form the fins may substantially increase heat flux to a silicon substrate relative to silicon fins. Furthermore, thermal-efficient materials may be used to form the source, drain, and channel structures to further spread heat and decrease hot spot temperatures.

Methods and apparatuses suitable for depositing low hydrogen content, hermetic, thin encapsulation layers at temperatures less than about 300° C. are provided herein. Methods involve pulsing plasma while exposing a substrate to deposition reactants, and post-treating deposited encapsulation films to densify and reduce hydrogen content. Post-treatment methods include periodic exposure to inert plasma without reactants and exposure to ultraviolet radiation at a substrate temperature less than about 300° C.

A peeling method of one embodiment of the present invention includes a first step of forming a first insulating layer over a substrate; a second step of forming a second insulating layer over the first insulating layer; a third step of forming a peeling layer over the second insulating layer; a fourth step of performing plasma treatment on a surface of the peeling layer; a fifth step of forming a third insulating layer over the peeling layer; a sixth step of performing heat treatment; and a seventh step of separating the peeling layer and the third insulating layer from each other. The first insulating layer and the third insulating layer each have a function of blocking hydrogen and for example, include a silicon nitride film or the like. The second insulating layer has a function of releasing hydrogen by heating and for example, includes a silicon oxide film.

A heating device for heating the surface of a substrate. The heating device comprises a gas source comprising an inert material supply inert under the operating conditions of the heating device, the gas source being adapted for supplying a hot jet of a gas comprising at least elements of said inert material on the substrate.
