Abstract: An aluminum-containing material deposition method includes depositing a first precursor on a substrate in the substantial absence of a second precursor. The first precursor can contain a chelate of Al(NR1R2)x(NR3(CH2)zNR4R5)y or Al(NR1R2)x(NR3(CH2)zOR4)y; where x is 0, 1, or 2; y is 3−x; z is an integer 2 to 8; and R1 to R5 are independently selected from among hydrocarbyl groups containing 1 to 10 carbon atoms with silicon optionally substituted for one or more carbon atoms. The method includes depositing the second precursor on the first deposited precursor, the second precursor containing a nitrogen source or an oxidant. A deposition product of the first and second precursors includes at least one of an aluminum nitride or an aluminum oxide. The deposition method can be atomic layer deposition where the first and second precursors are chemisorbed or reacted as monolayers. The first precursor can further be non-pyrophoric.

Abstract: In one aspect, the invention encompasses a semiconductor processing method of forming a metal-comprising layer over a substrate. A substrate is provided within a reaction chamber, and a source of a metal-comprising precursor is provided external to the reaction chamber. The metal-comprising precursor comprises a metal coordinated with at least one Lewis base to form a complex having a stoichiometric ratio of the at least one Lewis base to the metal. An amount of the at least one Lewis base is distributed within the source to an amount that is in excess of the stoichiometric ratio. At least some of the metal-comprising precursor is transported from the source to the reaction chamber. A metal is deposited from the metal-comprising precursor and onto the substrate within the reaction chamber. In another aspect, the invention encompasses a method of storing a metal-comprising material. A metal-comprising material is dispersed within a solution.

At least a fragment of a precursor material is chemisorbed on a substrate within the reaction chamber while not exposing the precursor material to microwave radiation from the source. Excess precursor material is removed from the chamber, and the chemisorbed material is subsequently exposed to microwave radiation from the source within the reaction chamber.

Abstract: 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.
