摘要:
Methods and devices for controlling a growth rate of films in semiconductor structures are shown. Chemical vapor deposition methods and devices include the use of a reaction inhibitor that selectively varies a deposition rate along a surface. One specific method includes atomic layer deposition. One method shown provides high step coverage over features such as trenches in trench plate capacitors. Also shown are methods and devices to provide uniform batch reactor layer thicknesses. Also shown are methods for forming alloy layers with high control over composition. Also shown are methods to selectively control growth rate to provide growth only on selected surfaces.

A capacitor includes a first capacitor electrode which includes conductive metal. A second capacitor electrode is spaced from the first capacitor electrode. A capacitor dielectric region is received between the first and second capacitor electrodes. Such region comprising a first portion oxide material of a first density over the first capacitor electrode, and a second portion oxide material of a second density received over the first portion. The oxide-comprising material of the first portion and the oxide-comprising material of the second portion are the same in chemical composition and the second density is greater than the first density.

The invention includes a method of depositing a noble metal. A substrate is provided. The substrate has a first region and a second region. The first and second regions are exposed to a mixture comprising a precursor of a noble metal and an oxidant. During the exposure, a layer containing the noble metal is selectively deposited onto the first region relative to the second region. In particular applications, the first region can comprise borophosphosilicate glass, and the second region can comprise either aluminum oxide or doped non-oxidized silicon. The invention also includes capacitor constructions and methods of forming capacitor constructions.
摘要:
The invention includes constructions having two dielectric layers over a conductively-doped semiconductive material. One of the dielectric layers contains aluminum oxide, and the other contains a metal oxide other than aluminum oxide (such metal oxide can be, for example, one or more of hafnium oxide, tantalum oxide, titanium oxide and zirconium oxide). The layer containing aluminum oxide is between the layer containing metal oxide and the conductively-doped semiconductive material. The invention includes capacitor devices having one electrode containing conductively-doped silicon and another electrode containing one or more metals and/or metal compounds. At least two dielectric layers are formed between the two capacitor electrodes, with one of the dielectric layers containing aluminum oxide and the other containing a metal oxide other than aluminum oxide. The invention also includes methods of forming capacitor constructions.
摘要:
The invention includes an atomic layer deposition method of forming a layer of a deposited composition on a substrate. The method includes positioning a semiconductor substrate within an atomic layer deposition chamber. On the substrate, an intermediate composition monolayer is formed, followed by a desired deposited composition from reaction with the intermediate composition, collectively from flowing multiple different composition deposition precursors to the substrate within the deposition chamber. A material adheres to a chamber internal component surface from such sequentially forming. After such sequentially forming, a reactive gas flows to the chamber which is different in composition from the multiple different deposition precursors and which is effective to react with such adhering material. After the reactive gas flowing, such sequentially forming is repeated. Further implementations are contemplated.
