    摘要: The present invention generally comprises a silicon dioxide atomic layer deposition method. By providing pyridine as a catalyst, water may be utilized as the oxidization source while depositing at a low temperature. Prior to exposing the substrate to the water, the substrate may be exposed to a pyridine soak process. Additionally, the water may be co-flowed to the chamber with the pyridine through separate conduits to reduce interaction prior to entering the chamber. Alternatively, the pyridine may be co-flowed with a silicon precursor that does not react with pyridine.

    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 a preferred example, a hafnium precursor is used during the ALD process to form a hafnium-containing material, such as hafnium oxide. In one example, the first and second oxidizing gases are the same oxidizing gases. In a preferred 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: A method for forming a refractory metal layer that features two-stage nucleation prior to bulk deposition of the same. The method includes placing a substrate in a deposition zone, flowing, into the deposition zone during a first deposition stage, a silicon source, such as a silane gas, and a tungsten source, such as tungsten-hexafluoride gas, so as to obtain a predetermined ratio of the two gases therein. During a second deposition stage, subsequent to the first deposition stage, the ratio of the two gases is varied. Specifically, in the first deposition stage there is a greater quantity of silane gas than tungsten-hexafluoride gas. In the second deposition stage there may be a greater quantity of tungsten-hexafluoride than silane.

    摘要: An apparatus and process for limiting residue remaining after the etching of metal in a semiconductor manufacturing process by injecting a halogen-containing gas without a plasma into a processing chamber. The wafer is then exposed to the remnants of the halogen-containing gas in the chamber before the metal is deposited on the wafer. The exposure can occur in the same chamber as the metal deposition, or a different chamber. The wafer can remain in the chamber or be moved to another chamber for etching after exposure and deposition.
