Patent ID: 8546276

Claim:
A method for depositing a group IV metal-containing film onto one or more substrates, comprising: a) providing a reactor and at least one substrate disposed in the reactor; b) providing a metal-containing precursor having the general formula: M(NR)X1 m X2 n (I) wherein: M is titanium, hafnium, or zirconium; R is selected from H; a C 1 -C 4 linear, branched, or cyclic alkyl or perfluoroalkyl group; or a C 1 -C 4 linear, branched, or cyclic alkylsilyl or perfluoroalkylsilyl group; X1 is selected from the group consisting of cyclopentadienyl, pentadienyl, cyclohexadienyl, hexadienyl, cycloheptadienyl, heptadienyl, cyclooctadienyl, and octadienyl, which may be substituted by a C 1 -C 4 linear, branched, or cyclic alkyl group; C 1 -C 4 linear, branched, or cyclic alkylsilyl group; C 1 -C 4 alkylamino group; a C 1 -C 4 linear, branched, or cyclic fluoroalkyl group; or combinations thereof; X2 is independently selected from the group consisting of hydrogen; oxygen; a linear, branched, or cyclic C 1 -C 8 alkyl; linear, branched, or cyclic C 1 -C 8 alkoxy; linear, branched, or cyclic C 1 -C 8 alkylamino; linear, branched, or cyclic C 1 -C 8 perfluoroalkyl; C 1 -C 4 linear, branched, or cyclic alkylsilyl; linear, branched, or cyclic C 1 -C 8 perfluoroalkoxy; C 1 -C 8 alkene; formamidinate; amidinate; guamidinate; carbonyl; nitrile; isocyanate; ethylene; halogen; alkyldienes; cycloalkyldienes; norbornadiene; diazabutadiene; ethylenediamine; ethanolamine; β-diketonate; β-diketiminate; and β-enaminoketonate, which may be substituted by C 1 -C 4 linear, branched, or cyclic alkyl group; C 1 -C 4 alkylamino group; a C 1 -C 4 linear, branched, or cyclic fluoroalkyl group; or combinations thereof; m=1; and n=1; c) vaporizing the metal-containing precursor to form a vaporized precursor; d) introducing the vaporized precursor into the reactor; and e) depositing at least part of the vaporized precursor onto the substrate to form a group IV metal-containing film.
