摘要:
Systems and methods for preparing inorganic-organic interfaces using organo-transition metal complexes and self-assembled monolayers as organic surfaces. In one embodiment, a silicon wafer is cleaned and reacted with stabilized pirhana etch to provide an oxide surface. The surface is reacted with the trichlorosilyl end of alkyltrichlorosilanes to prepare self assembling monomers (SAMs). The alkyltrichlorosilanes have the general formula R1-R—SiCl3, where R1 is —OH, —NH2, —COOH, —SH, COOCH3, —CN, and R is a conjugated hydrocarbon, such as (CH2)n where n is in the range of 3 to 18. The functionalized end of the SAM can optionally modified chemically as appropriate, and is then reacted with metal-bearing species such as tetrakis(dimethylamido)titanium, Ti[N(CH3)2]4, (TDMAT) to provide a titanium nitride layer.

Provided are methods of forming a ternary metal nitride film and more specifically, a TaSiN film. A metal nitride film, or TaN film, is deposited on a substrate with plasma treatment. A SiN layer is deposited on the metal nitride, or TaN, film to form a metal-SiN, or TaSiN, film. The film is then annealed to provide a metal nitride film with stable resistivity.

Embodiments of the invention relate to apparatuses and methods for depositing materials on substrates during atomic layer deposition processes. In one embodiment, a chamber for processing substrates is provided which includes a chamber lid assembly containing an expanding channel extending along a central axis at a central portion of the chamber lid assembly and a tapered bottom surface extending from the expanding channel to a peripheral portion of the chamber lid assembly. The tapered bottom surface may be shaped and sized to substantially cover the substrate receiving surface. The chamber lid assembly further contains a conduit coupled to a gas passageway, another conduit coupled to another gas passageway, and both gas passageways circumvent the expanding channel. Each of the passageways has a plurality of inlets extending into the expanding channel and the inlets are positioned to provide a circular gas flow through the expanding channel.

Embodiments of the invention generally provide methods for depositing metal-containing materials and compositions thereof. The methods include deposition processes that form metal, metal carbide, metal silicide, metal nitride, and metal carbide derivatives by a vapor deposition process, including thermal decomposition, CVD, pulsed-CVD, or ALD. In one embodiment, a method for processing a substrate is provided which includes depositing a dielectric material having a dielectric constant greater than 10, forming a feature definition in the dielectric material, depositing a work function material conformally on the sidewalls and bottom of the feature definition, and depositing a metal gate fill material on the work function material to fill the feature definition, wherein the work function material is deposited by reacting at least one metal-halide precursor having the formula MXY, wherein M is tantalum, hafnium, titanium, and lanthanum, X is a halide selected from the group of fluorine, chlorine, bromine, or iodine, and y is from 3 to 5.
