Abstract
Group 4 transition metal-containing film forming compositions are disclosed. The Group 4 transition metal-containing film forming compositions comprise Group 4 transition metal precursors having the formula L-M-CR-[(ER)—NR]—, wherein M is Ti, Zr, or Hf bonded in an ηbonding mode to the Cp group; each E is independently C, Si, B or P; each R is independently a hydrogen or a C-Chydrocarbon group; and each L is independently a −1 anionic ligand selected from the group consisting of NR', OR′, Cp, amidinate, β-diketonate, or keto-iminate, wherein R′ is a H or a C-Chydrocarbon group and adjacent R′s may be joined to form a hydrocarbyl ring; provided that at least one R on the Cp is Cto C. Also disclosed are methods of synthesizing and using the disclosed precursors to deposit Group 4 transition metal-containing films on one or more substrates via vapor deposition processes.
