Patent ID: 7105444

Claim:
A method for forming a wiring of a semiconductor device, the method comprising: a) forming an first insulating interlayer on a substrate; b) introducing tantalum amine derivatives onto the first insulating interlayer, the tantalum amine derivatives comprising Ta(NC(CH 3 ) 2 C 2 H 5 )(N(CH 3 ) 2 ) 3 ); c) chemisorbing a portion of the tantalum amine derivatives on a surface of the first insulating interlayer; d) removing non-chemisorbed tantalum amine derivatives from the surface of the first insulating interlayer; e) introducing a reacting gas onto the first insulating interlayer; and f) removing a ligand in the tantalum amine derivatives chemisorbed on the first insulating interlayer from the tantalum amine derivatives.
