    摘要: In some embodiments of the present invention, methods of forming a tantalum carbon nitride layer include introducing a source gas including a tantalum metal complex onto a substrate, wherein one or more of the ligands of the tantalum metal complex include nitrogen and one or more of the ligands of the tantalum metal complex include carbon; and thermally decomposing the tantalum metal complex to form a tantalum carbon nitride layer on the substrate. In some embodiments, the tantalum metal complex includes Ta(NR1)(NR2R3)3, wherein R1, R2 and R3 are each independently H or a C1-C6 alkyl group. In some embodiments, the tantalum metal complex may be [Ta(═NC(CH3)2C2H5)(N(CH3)2)3]. Methods of forming a gate structure, methods of manufacturing dual gate electrodes and methods of manufacturing a capacitor including tantalum carbon nitride are also provided herein.
