Raw material for forming thin film, and method for manufacturing thin film
A raw material for forming a thin film that includes a compound represented by General Formula (1) below. In the formula, R 1 represents a linear or branched alkyl group having 2 to 4 carbon atoms; R 2 to R 5 each independently represent a linear or branched alkyl group having 1 to 4 carbon atoms; A represents an alkanediyl group having 1 to 4 carbon atoms; and M represents titanium, zirconium or hafnium. Provided that when M represents zirconium, A represents an alkanediyl group having 3 or 4 carbon atoms. When M represents titanium or hafnium, it is preferred that A represents an alkanediyl group having 2 or 3 carbon atoms. When M represents zirconium, it is preferred that A represent an alkanediyl group having 3 carbon atoms.
1. A method for manufacturing a thin film, comprising: introducing a vapor including at least one compound selected from the group consisting of Compound No. 34 and Compound No. 66, which is obtained by vaporizing a raw material for forming a thin film that includes the at least one compound, into a film formation chamber in which a substrate is disposed; and forming, on a surface of the substrate, a thin film including at least one atom selected from the group consisting of zirconium and hafnium by inducing decomposition and/or chemical reaction of the at least one compound:
2. The method for manufacturing a thin film according to claim 1 , wherein a groove having an aspect ratio of 10 to 200 is formed on the substrate.
3. A method for manufacturing a thin film, comprising: introducing a vapor including at least one compound selected from the group consisting of Compound No. 34 and Compound No. 66, which is obtained by vaporizing a raw material for forming a thin film by an ALD method that includes the at least one compound, into a film formation chamber in which a substrate is disposed; and forming, on a surface of the substrate, a thin film including at least one atom selected from the group consisting of zirconium and hafnium by inducing decomposition and/or chemical reaction of the at least one compound:
4. The method for manufacturing a thin film according to claim 3 , wherein a groove having an aspect ratio of 10 to 200 is formed on the substrate.
