Patent ID: 8357614

Claim:
A method of forming a ruthenium-containing layer on a substrate, the method comprising: a) providing a reaction chamber having at least one substrate disposed therein; b) introducing into the reaction chamber a vapor comprising at least one compound having the formula [L] m Ru(CO) 3 , wherein L is selected from the group consisting of ethylene, propylene, butene, 2,4-pentadiene, 2-methyl-2,4-pentadiene, 1,4-pentadiene, 2,4-hexadiene, 2,4-hexadienal, 2,4-heptadiene, 1,4-dimethyl-1,3-cyclohexadiene, 1-methyl-4-ethyl-1,3-cyclohexadiene, 1-methyl-4-n-propyl-1,3-cyclohexadiene, 1-methyl-4-isopropyl-1,3-cyclohexadiene, 1-methyl-5-methyl-1,4-cyclohexadiene, 1-methyl-5-ethyl-1,4-cyclohexadiene, 1-methyl-5-n-propyl-1,4-cyclohexadiene, and 1-methyl-5-isopropyl-1,4-cyclohexadiene and m is 1 or 2; and c) contacting the vapor with the substrate to form the ruthenium-containing layer on at least one surface of the substrate using a vapor deposition process.
