    摘要: 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.

    摘要: An atomic layer deposition method includes positioning a semiconductor substrate within an atomic layer deposition chamber. A first precursor gas is flowed to the substrate within the atomic layer deposition chamber effective to form a first monolayer on the substrate. The first precursor gas flowing comprises a plurality of first precursor gas pulses. The plurality of first precursor gas pulses comprises at least one total period of time between two immediately adjacent first precursor gas pulses when no gas is fed to the chamber. After forming the first monolayer on the substrate, a second precursor gas different in composition from the first is flowed to the substrate within the deposition chamber effective to form a second monolayer on the first monolayer. Other aspects and implementations are contemplated.

    摘要: The invention includes methods of forming metal oxide and/or semimetal oxide. The invention can include formation of at least one metal-and-halogen-containing material and/or at least one semimetal-and-halogen-containing material over a semiconductor substrate surface. The material can be subjected to aminolysis followed by oxidation to convert the material to metal oxide and/or semimetal oxide. The aminolysis and oxidation can be separate ALD steps relative to one another, or can be conducted in a reaction chamber in a common processing step.

    摘要: Isolated conductive nanoparticles on a dielectric layer and methods of fabricating such isolated conductive nanoparticles provide charge storage units in electronic structures for use in a wide range of electronic devices and systems. The isolated conductive nanoparticles may be used as a floating gate in a flash memory. In an embodiment, conductive nanoparticles are deposited on a dielectric layer by a plasma-assisted deposition process such that each conductive nanoparticle is isolated from the other conductive nanoparticles to configure the conductive nanoparticles as charge storage elements.
