Abstract:
1. A method of forming a thin film containing a metal oxide as a main component on a substrate using a mixed gas stream containing a metal chloride, an oxidizing material, and hydrogen chloride by a thermal decomposition method at a film deposition rate of 4500 nm/min. or greater, the method characterized by performing at least one selected from: 1) prior to mixing the metal chloride and the oxidizing material in the mixed gas stream, contacting the hydrogen chloride with at least one selected from the metal chloride and the oxidizing material; and 2) forming a buffer layer in advance on a surface of the substrate on which the thin film containing a metal oxide as the main component is to be formed.
