Patent ID: 7374701

Claim:
A composition for forming a metal film or pattern, which comprises (i) an organometallic precursor represented by the following Formula 1 and (ii) an organometallic compound of a main group metal not represented by the following Formula 1: L n M m L′ p X q Formula 1 wherein, M is a transition metal; L′ is a neutral ligand; X is an anion that may or may not coordinate to the transition metal; m is an integer of 1 to 10, provided that when m is two or more, each M is independently the same or different; n is an integer of 1 to 40, provided that when n is two or more, each L is independently the same or different; p is an integer of 0 to 40; q is an integer of 0 to 10, provided that when p or q is two or higher, each L′ or each X is independently the same or different, and p and q are not zero at the same time; and L is a hydrazine compound coordinating with the transition metal, and is represented by the following Formula 2: R 1 R 2 NNR 3 R 4 Formula 2 wherein, R 1 , R 2 , R 3 and R 4 are independently hydrogen, C 1 ˜C 20 alkyl group, C 1 ˜C 20 aryl group, or [in which, R 5 is R′, R′ 2 N, or R′O (wherein R′ is hydrogen, or C 1 ˜C 20 alkyl or aryl group)], provided that the alkyl and aryl group may or may not have one or more substituent which is selected from the group consisting of halogen, amine group, —OH, —SH, —CN, —SO 3 H, R 6 S—, R 6 O—, and nitrile groups (in which, R 5 is defined as above and R 6 is C 1 ˜C 20 alkyl or aryl group).
