Ti, Ta, Hf, Zr and related metal silicon amides for ALD/CVD of metal-silicon nitrides, oxides or oxynitrides

An organometallic complex represented by the structure: wherein M is a metal selected from Group 4 of the Periodic Table of the Elements and R 1-4 can be same or different selected from the group consisting of dialkylamide, difluoralkylamide, hydrogen, alkyl, alkoxy, fluoroalkyl and alkoxy, cycloaliphatic, and aryl with the additional provision that when R 1 and R 2 are dialkylamide, difluoralkylamide, alkoxy, fluoroalkyl and alkoxy, they can be connected to form a ring. Related compounds are also disclosed. CVD and ALD deposition processes using the complexes are also included.
