Patent ID: 7077902

Claim:
An aluminum-containing material deposition method comprising: depositing a first precursor on a substrate while preventing gas phase reaction of the first precursor and a second precursor with which the first precursor otherwise exhibits gas phase reactivity, the first precursor comprising a chelate of Al(NR 1 R 2 ) x (NR 3 (CH 2 ) z NR 4 R 5 ) y or Al(NR 1 R 2 ) x (NR 3 (CH 2 ) z OR 4 ) y ; where x is 0, 1, or 2; y is 3−x; z is an integer from 2 to 8; and R 1 to R 5 are independently selected from among hydrocarbyl groups comprising 1 to 10 carbon atoms with silicon optionally substituted for one or more carbon atoms; and reacting the deposited first precursor with the second precursor and forming an aluminum-containing material.
