Abstract:
1. A method for forming a TiSiN thin film on a substrate according to atomic layer deposition (ALD), the method comprising: a first process of preheating the substrate while supplying Ar or N a second process of forming a TiN film on the substrate, the second process comprising a first plurality of steps: a third process of forming a SiN film, the third process comprising a second plurality of steps: a fourth process of forming a TiSiN film having a desired thickness by repeating the second and third processes at least one time, wherein a partial pressure range of the gas used in forming the TiSiN thin film is Ti containing gas: 9×10 the method characterized in that in the second process, the first plurality of steps are repeated at least one time prior to the third process, and that in the third process, the second plurality of steps are repeated at least one time prior to the fourth process.
