Title:
CHEMICAL VAPOR DEPOSITION MATERIAL FORMED OF RUTHENIUM COMPLEX, METHOD FOR PRODUCING SAME AND CHEMICAL VAPOR DEPOSITION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/030609
Kind Code:
A1
Abstract:
The present invention is a chemical vapor deposition material for producing a ruthenium thin film or a ruthenium compound thin film by a chemical vapor deposition method, said chemical vapor deposition material being formed of a ruthenium complex which is represented by the formula described below and in which a carbonyl group and a fluoroalkyl derivative of a polyene are coordinated to ruthenium. The present invention provides a chemical vapor deposition material which is formed of a ruthenium complex that is produced at low cost and has a suitable decomposition temperature. (nR-L)Ru(CO)3 (In the formula, L represents a polyene having 4-8 carbon atoms and 2-4 double bonds; the polyene L has an n-number (n ≥ 1) of substituent R; and each substituent R represents a fluoroalkyl group having 1-6 carbon atoms and 1-13 fluorine atoms. In cases where the polyene L has two or more substituents R (n ≥ 2), the substituents R may have different numbers of carbon atoms and different numbers of fluorine atoms in each molecule.)
