Diazadienyl compound, raw material for forming thin film, and method for manufacturing thin film
A diazadienyl compound represented by General Formula (I) below: wherein R 1 represents a C 1-6 linear or branched alkyl group, and M represents nickel atom or manganese atom. In particular, since a compound in which R 1 in General Formula (I) is a methyl group has a high vapor pressure and a high thermal decomposition starting temperature, the compound is useful as a raw material for forming a thin film by a CVD method or ALD method.
1. A method for manufacturing a thin film, comprising the steps of:
introducing a vapor including a diazadienyl compound obtained by vaporizing a raw material for forming a thin film comprising the diazadienyl compound and a reactive gas into a film formation chamber in which a substrate is disposed, wherein the diazadienyl compound is represented by Formula (I) below:
wherein R 1 represents a C 1-6 linear or branched alkyl group, and M represents nickel atom or manganese atom; and
forming, on a surface of the substrate, a thin film including at least one atom selected from nickel atom and manganese atom by inducing decomposition and/or chemical reaction of the diazadienyl compound.
2. The method for manufacturing a thin film according to claim 1 , wherein the reactive gas is hydrogen.
3. The method for manufacturing a thin film according to claim 1 , wherein R 1 in Formula (I) is a methyl group.
4. The method for manufacturing a thin film according to claim 3 , wherein the reactive gas is hydrogen.
