Patent ID: 8309174

Claim:
A process for the deposition of a iridium containing film on a substrate, the process comprising the steps of: A) providing at least one substrate in a reactor; B) introducing into the reactor at least one iridium containing precursor having the formula: XIrY A , i) when A is 1, (a) X is a dienyl ligand selected from 6,6-dimethylcyclohexadienyl, 2,6,6-trimethylcyclohexadienyl, or 6-oxo-2-methylcyclohexadienyl; Y is a diene ligand selected from butadiene, cyclopentadiene, pentadiene, hexadiene, 1,3-cyclohexadiene, 1,4-cyclohexadiene, and oxocyclohexadiene, each diene ligand optionally substituted with one or more substituents R2, each R2 being independently selected from H, O, C 1 to C 4 linear or branched alkyl, C 1 to C 4 linear or branched alkylamides, C 1 to C 4 linear or branched alkoxides, C 1 to C 4 linear or branched alkylsilyls, C 1 to C 4 linear or branched alkylsilylamides, and C 1 to C 4 linear or branched fluoroalkyl; or (b) X is a cyclopentadienyl (Cp) substituted with 1 to 3 C 1 to C 4 alkyl groups; Y is a substituted 1,4-cyclohexadiene; C) reacting the at least one iridium containing precursor in the reactor at a temperature equal to or greater than 100° C.; and D) depositing an iridium containing film formed from the reaction of the at least one iridium containing precursor onto the at least one substrate.
