Abstract

Disclosed are Germanium- and Zirconium-containing precursors having one of the following formulae:wherein each R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 is independently selected from H; a C1-C5 linear, branched, or cyclic alkyl group; and a C1-C5 linear, branched, or cyclic fluoroalkyl groups. Also disclosed are methods of synthesizing the disclosed precursors and using the same to deposit Zirconium-containing films on substrates via vapor deposition processes.
