摘要:
A unique electrochemical process fills oxygen vacancies in dielectrics while reducing oxidation of nearby electrodes and conductors. Preferably, an electromagnetic field or bias is applied to a dielectric. The bias causes oxygen vacancies in the dielectric to migrate to the surface of the dielectric. As the oxygen vacancies migrate toward the surface, oxygen ions fill the oxygen vacancies. In one embodiment, a unique plasma treatment provides the oxygen ions that react with the oxygen vacancies. In another embodiment, a unique electrolysis treatment provides the oxygen ions that react with the oxygen vacancies.

The invention comprises methods of forming pluralities of capacitors. In one implementation, metal is formed over individual capacitor storage node locations on a substrate. A patterned masking layer is formed over the metal. The patterned masking layer comprises openings therethrough to an outer surface of the metal. Individual of the openings are received over individual of the capacitor storage node locations. A pit is formed in the metal outer surface within individual of the openings. After forming the pits, the metal is anodically oxidized through the openings effective to form a single metal oxide-lined channel in individual of the openings over the individual capacitor storage nodes. Individual capacitor electrodes are formed within the channels in electrical connection with the individual capacitor storage node locations. At least some of the metal oxide is removed from the substrate, and the individual capacitor electrodes are incorporated into a plurality of capacitors. Other aspects and implementations are contemplated.

One-transistor memory devices facilitate nonvolatile data storage through the manipulation of oxygen vacancies within a trapping layer of a field-effect transistor (FET), thereby providing control and variation of threshold voltages of the transistor. Various threshold voltages may be assigned a data value, providing the ability to store one or more bits of data in a single memory cell. To control the threshold voltage, the oxygen vacancies may be manipulated by trapping electrons within the vacancies, freeing trapped electrons from the vacancies, moving the vacancies within the trapping layer and annihilating the vacancies.

Chemical vapor deposition methods of forming titanium suicide including layers on substrates are disclosed. TiCl4 and at least one silane are first fed to the chamber at or above a first volumetric ratio of TiCl4 to silane for a first period of time. The ratio is sufficiently high to avoid measurable deposition of titanium silicide on the substrate. Alternately, no measurable silane is fed to the chamber for a first period of time. Regardless, after the first period, TiCl4 and at least one silane are fed to the chamber at or below a second volumetric ratio of TiCl4 to silane for a second period of time. If at least one silane was fed during the first period of time, the second volumetric ratio is lower than the first volumetric ratio. Regardless, the second feeding is effective to plasma enhance chemical vapor deposit a titanium silicide including layer on the substrate.

In one implementation, a method of forming epitaxial silicon-comprising material includes providing a substrate comprising monocrystalline material. A first portion of the monocrystalline material is outwardly exposed while a second portion of the monocrystalline material is masked. A first silicon-comprising layer is epitaxially grown from the exposed monocrystalline material of the first portion and not from the monocrystalline material of the masked second portion. After growing the first silicon-comprising layer, the second portion of the monocrystalline material is unmasked. A second silicon-comprising layer is then epitaxially grown from the first silicon-comprising layer and from the unmasked monocrystalline material of the second portion. Other aspects and implementations are contemplated.

The invention includes methods in which metal oxide dielectric materials are deposited over barrier layers. The barrier layers can comprise compositions of metal and one or more of carbon, boron and nitrogen, and the metal oxide of the dielectric material can comprise the same metal as the barrier layer. The dielectric material/barrier layer constructions can be incorporated into capacitors. The capacitors can be used in, for example, DRAM cells, which in turn can be used in electronic systems.
