Organic aluminum precursor and method of manufacturing a metal wiring using the same

A method of manufacturing a metal wiring, comprising:

• applying an organic aluminum precursor to a substrate, the organic aluminum precursor having aluminum as a central metal;
• thermally decomposing the organic aluminum precursor over the substrate;
• and
• depositing the thermally decomposed organic aluminum precursor on the substrate to form an aluminum layer on the substrate,
• wherein the organic aluminum precursor includes dimethylamino-2-methylpropyl methyl aluminum hydride,
• wherein the organic aluminum precursor is contained in a canister at a temperature of about 60° C. to about 65° C. prior to application of the organic aluminum precursor to the substrate,
• wherein the organic aluminum precursor is decomposed on the substrate supported by a suscepter having a temperature of about 120° C. to 220° C., and
• wherein the aluminum layer has a resistance of less than about 2 ohm/sq, and
• wherein the organic aluminum precursor has a vapor pressure of about 1.1 torr to about 1.3 torr in the canister at a temperature of about 60° C.
