Abstract:
An aluminum-containing material deposition method comprising:depositing a first precursor on a substrate in the substantial absence of a second precursor, the first precursor exhibiting gas phase reactivity with the second precursor, the first precursor comprising 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 3âˆ’x; z is an integer from 2 to 8; and R1 to R5 are independently selected from among hydrocarbyl groups comprising 1 to 10 carbon atoms with silicon optionally substituted for one or more carbon atoms; and depositing the second precursor on the first deposited precursor in the substantial absence of a non-deposited first precursor, the second precursor comprising at least one of a nitrogen source and an oxidant, and a deposition product of the first and second precursors comprising at least one of an aluminum nitride or an aluminum oxide.
