摘要： A deposition process including a dry etch process, followed by a deposition process of a high-k dielectric is disclosed. The dry etch process involves placing a substrate to be cleaned into a processing chamber to remove surface oxides. A gas mixture is energized to form a plasma of reactive gas which reacts with an oxide on the substrate, forming a thin film. The substrate is heated to vaporize the thin film and expose a substrate surface. The substrate surface is substantially free of oxides. Deposition is then used to form a layer on the substrate surface.

摘要： Methods for preparing a substrate for a subsequent film formation process are described. Methods for preparing a substrate for a subsequent film formation process, without immersion in an aqueous solution, are also described. A process is described that includes disposing a substrate into a process chamber, the substrate having a thermal oxide surface with substantially no reactive surface terminations. The thermal oxide surface is exposed to a partial pressure of water below the saturated vapor pressure at a temperature of the substrate to convert the dense thermal oxide with substantially no reactive surface terminations to a surface with hydroxyl surface terminations. This can occur in the presence of a Lewis base such as ammonia.

摘要： Embodiments of the invention provide methods for forming a material on a substrate which includes exposing a plurality of substrates within a batch process chamber to a first oxidizing gas during a pretreatment process, exposing the substrates sequentially to a precursor and a second oxidizing gas during an ALD cycle and repeating the ALD cycle to form a material on the substrates. In one example, a hafnium precursor is used during the ALD process to form a hafnium-containing material, such as hafnium oxide. In another example, the first and second oxidizing gases are the same oxidizing gases. In another example, the first and second oxidizing gases are different oxidizing gases, such that the pretreatment process contains ozone and the ALD process contains water vapor.

摘要： Atomic layer deposition methods of forming one or more of a mixed silicon oxide/silicon nitride film or a mixed silicon oxide/silicon film are described in which the substrate is exposed sequentially to a first reactant gas comprising a silicon species and a second reactant gas comprising an oxygen species to form at least a partial layer of silicon oxide on the substrate during a first atomic layer deposition process. The substrate is then exposed sequentially to a third reactant gas comprising a silicon species and a fourth reactant gas comprising a species sufficient to form at least a partial layer of one or more of silicon nitride or silicon on the substrate during a second atomic layer deposition process. The process can be repeated multiple times to deposit one or more of a mixed silicon oxide/silicon nitride film and a mixed silicon oxide/silicon film.
