    摘要: The invention includes methods of forming conductive metal silicides by reaction of metal with silicon. In one implementation, such a method includes providing a semiconductor substrate comprising an exposed elemental silicon containing surface. At least one of a crystalline form TiN, WN, elemental form W, or SiC comprising layer is deposited onto the exposed elemental silicon containing surface to a thickness no greater than 50 Angstroms. Such layer is exposed to plasma and a conductive reaction layer including at least one of an elemental metal or metal rich silicide is deposited onto the plasma exposed layer. At least one of metal of the conductive reaction layer or elemental silicon of the substrate is diffused along columnar grain boundaries of the crystalline form layer effective to cause a reaction of metal of the conductive reaction layer with elemental silicon of the substrate to form a conductive metal silicide comprising contact region electrically connecting the conductive reaction layer with the substrate. Other aspects and implementations are contemplated.

    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. After forming the first monolayer, a reactive intermediate gas is flowed to the substrate within the deposition chamber. The reactive intermediate gas is capable of reaction with an intermediate reaction by-product from the first precursor flowing under conditions of the reactive intermediate gas flowing. After flowing the reactive intermediate gas, a second precursor gas 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 films over substrates. A substrate is provided within a reaction chamber, and a mixture is also provided within the chamber. The mixture includes a precursor of a desired material within a supercritical fluid. The precursor is relatively reactive under one set of conditions and is relatively non-reactive under another set of conditions. The precursor and supercritical fluid mixture is initially provided in the chamber under the conditions at which the precursor is relatively non-reactive. Subsequently, and while maintaining the supercritical state of the supercritical fluid, the conditions within the reaction chamber are changed to the conditions under which the precursor is relatively reactive. The precursor reacts to form the desired material, and at least some of the desired material forms a film on the substrate.

    摘要: The invention includes methods of forming regions of differing composition over a substrate. A first material having a pattern of at least one substantially amorphous region and at least one substantially crystalline region is provided over the substrate. The at least one substantially amorphous region of the first material replaced with a second material, while the at least one substantially crystaline region is not replaced. The invention also includes a circuit construction comprising an electrically conductive material extending within openings in a substantially crystalline electrically insulative material, and in which the electrically conductive material corresponds to quantum dots.
