  • Publication number: 20100276656
    Abstract: Some embodiments include devices that contain bundles of CNTs. An undulating topography extends over the CNTs and within spaces between the CNTs. A global maximum lateral width is defined as the greatest lateral width of any of the spaces. A material is directly over the CNTs, with the material being a plurality of particles that have minimum cross-sectional equatorial widths exceeding the global maximum lateral width. Some embodiments include methods in which a plurality of crossed carbon nanotubes are formed over a semiconductor substrate. The CNTs form an undulating upper topography extending across the CNTs and within spaces between the CNTs. A global maximum lateral width is defined as the greatest lateral width of any of the spaces. A material is deposited over the CNTs, with the material being deposited as particles that have minimum cross-sectional equatorial widths exceeding the global maximum lateral width.

  • Publication number: 20100267246
    Abstract: Embodiments disclosed herein pertain to silicon dioxide deposition methods using at least ozone and tetraethylorthosilicate (TEOS) as deposition precursors. In one embodiment, a silicon dioxide deposition method using at least ozone and TEOS as deposition precursors includes flowing precursors comprising ozone and TEOS to a substrate under subatmospheric pressure conditions effective to deposit silicon dioxide-comprising material having an outer surface onto the substrate. The outer surface is treated effective to one of add hydroxyl to or remove hydroxyl from the outer surface in comparison to any hydroxyl presence on the outer surface prior to said treating. After the treating, precursors comprising ozone and TEOS are flowed to the substrate under subatmospheric pressure conditions effective to deposit silicon dioxide-comprising material onto the treated outer surface of the substrate. Other embodiments are contemplated.

  • Publication number: 20100258903
    Abstract: Strontium ruthenium oxide provides an effective interface between a ruthenium conductor and a strontium titanium oxide dielectric. Formation of the strontium ruthenium oxide includes the use of atomic layer deposition to form strontium oxide and subsequent annealing of the strontium oxide to form the strontium ruthenium oxide. A first atomic layer deposition of strontium oxide is preformed using water as an oxygen source, followed by a subsequent atomic layer deposition of strontium oxide using ozone as an oxygen source.

  • Publication number: 20100230813
    Abstract: The invention includes methods of forming layers conformally over undulating surface topographies associated with semiconductor substrates. The undulating surface topographies can first be exposed to one or more of titanium oxide, neodymium oxide, yttrium oxide, zirconium oxide and vanadium oxide to treat the surfaces, and can be subsequently exposed to a material that forms a layer conformally along the treated surfaces. The material can, for example, comprise one or both of aluminum silane and aluminum silazane. The invention also includes semiconductor constructions having conformal layers formed over liners containing one or more of titanium oxide, yttrium oxide, zirconium oxide and vanadium oxide.

  • Publication number: 20100227281
    Abstract: Some embodiments include methods of forming patterns of openings. The methods may include forming spaced features over a substrate. The features may have tops and may have sidewalls extending downwardly from the tops. A first material may be formed along the tops and sidewalls of the features. The first material may be formed by spin-casting a conformal layer of the first material across the features, or by selective deposition along the features relative to the substrate. After the first material is formed, fill material may be provided between the features while leaving regions of the first material exposed. The exposed regions of the first material may then be selectively removed relative to both the fill material and the features to create the pattern of openings.

  • Publication number: 20100221920
    Abstract: Methods are disclosed, such as those involving increasing the density of isolated features in an integrated circuit. Also disclosed are structures associated with the methods. In one or more embodiments, contacts are formed on pitch with other structures, such as conductive interconnects. The interconnects may be formed by pitch multiplication. To form the contacts, in some embodiments, a pattern corresponding to some of the contacts is formed in a selectively definable material such as photoresist. The features in the selectively definable material are trimmed to desired dimensions. Spacer material is blanket deposited over the features in the selectively definable material and the deposited material is then etched to leave spacers on sides of the features. The selectively definable material is removed to leave a mask defined by the spacer material. The pattern defined by the spacer material may be transferred to a substrate, to form on pitch contacts.

  • Patent number: 7659181
    Abstract: A method of depositing dielectric material into sub-micron spaces and resultant structures is provided. After a trench is etched in the surface of a wafer, an oxygen barrier is deposited into the trench. An expandable, oxidizable liner, preferably amorphous silicon, is then deposited. The trench is then filled with a spin-on dielectric (SOD) material. A densification process is then applied, whereby the SOD material contracts and the oxidizable liner expands. Preferably, the temperature is ramped up while oxidizing during at least part of the densification process. The resulting trench has a negligible vertical wet etch rate gradient and a negligible recess at the top of the trench.
