    摘要: This invention includes methods of depositing a silicon dioxide comprising layer in the fabrication of integrated circuitry, and to methods of forming trench isolation in the fabrication of integrated circuitry. In one implementation, a method of depositing a silicon dioxide comprising layer in the fabrication of integrated circuitry includes flowing an aluminum containing organic precursor to a chamber containing a semiconductor substrate effective to deposit an aluminum comprising layer over the substrate. An alkoxysilanol is flowed to the substrate comprising the aluminum comprising layer within the chamber effective to deposit a silicon dioxide comprising layer over the substrate. At least one halogen is provided within the chamber during at least one of the aluminum containing organic precursor flowing and the alkoxysilanol flowing under conditions effective to reduce rate of the deposit of the silicon dioxide comprising layer over the substrate than would otherwise occur under identical conditions but for providing the halogen. Other implementations are contemplated.

    摘要: CVD, ALD, and other vapor processes used in processing semiconductor workpieces often require volatilizing a liquid or solid precursor. Certain embodiments of the invention provide improved and/or more consistent volatilization rates by moving a reaction vessel. In one exemplary embodiment, a reaction vessel is rotated about a rotation axis which is disposed at an angle with respect to vertical. This deposits a quantity of the reaction precursor on an interior surface of the vessel's sidewall which is exposed to the headspace as the vessel rotates. Other embodiments employ drivers adapted to move the reaction vessel in other manners, such as a pendulum arm to oscillate the vessel along an arcuate path or a mechanical linkage which moves the vessel along an elliptical path.

    摘要: Chemical vapor deposition systems include elements to preheat reactant gases prior to reacting the gases to form layers of a material on a substrate, which provides devices and systems with deposited layers substantially free of residual compounds from the reaction process. Heating reactant gases prior to introduction to a reaction chamber may be used to improve physical characteristics of the resulting deposited layer, to improve the physical characteristics of the underlying substrate and/or to improve the thermal budget available for subsequent processing. One example includes the formation of a titanium nitride layer substantially free of ammonium chloride using reactant gases containing a titanium tetrachloride precursor and a ammonia precursor.

    摘要: The invention includes methods of forming films over substrates. A substrate is provided within a reaction chamber, and a mixture is also provided within the chamber. The mixture comprises a precursor of a desired material within a supercritical fluid. The precursor is relatively reactive under one set of conditions and is relatively non-reactive under another set of conditions. The precursor and supercritical fluid mixture is initially provided in the chamber under the conditions at which the precursor is relatively non-reactive. Subsequently, and while maintaining the supercritical state of the supercritical fluid, the conditions within the reaction chamber are changed to the conditions under which the precursor is relatively reactive. The precursor reacts to form the desired material, and at least some of the desired material forms a film on the substrate.

    摘要: An MIS capacitor with low leakage and high capacitance is disclosed. A layer of hemispherical grained polysilicon (HSG) is formed as a lower electrode. Prior to the dielectric formation, the hemispherical grained polysilicon layer may be optionally subjected to a nitridization or anneal process. A dielectric layer of aluminum oxide (Al2O3), or a composite stack of interleaved layers of aluminum oxide and other metal oxide dielectric materials, is fabricated over the hemispherical grained polysilicon layer and after the optional nitridization or anneal process. The dielectric layer of aluminum oxide (Al2O3) or the aluminum oxide composite stack may be optionally subjected to a post-deposition treatment to further increase the capacitance and decrease the leakage current. A metal nitride upper electrode is formed over the dielectric layer or the composite stack by a deposition technique or by atomic layer deposition.

The masking material comprises at least one of tungsten, titanium nitride and amorphous carbon. An opening is formed through the masking material and into the semiconductor substrate effective to form an isolation trench within semiconductive material of the semiconductor substrate. A trench isolation material is formed within the isolation trench and over the masking material outside of the trench effective to overfill the isolation trench. The trench isolation material is polished at least to an outermost surface of the at least one of tungsten, titanium nitride and amorphous carbon of the masking material. The at least one of tungsten, titanium nitride and amorphous carbon is/are etched from the substrate. Other implementations and aspects are contemplated.

    摘要: A method of depositing a thin film on a substrate in a semiconductor device using Atomic Layer Deposition (ALD) process parameters exposes the substrate to at least one adherent material in a quantity sufficient for the material to adsorb onto the substrate and thereby form an initiation layer. The initiation layer presents at least one first reactive moiety which is then chemically reacted with at least one first reaction material using atomic layer deposition conditions to form a second reactive moiety. The second reactive moiety is then chemically reacted with at least one second reaction material under process conditions sufficient to form a reaction layer over the initiation layer. The process may be repeated to form successive reaction layers over the initiation layer. The adherent material constituting the initiation layer is preferably one which is not substantially degraded by the atomic layer deposition parameters. The initiation layer together with one or more reaction layer(s) constitutes the final film.
