Patent ID: 8093490

Claim:
A method of forming a transparent conductive film that is a thin film containing a crystalline metal oxide as a main component on a glass substrate by a thermal decomposition method, comprising: forming an undercoating film containing silicon oxide as a main component on the glass substrate; forming the transparent conductive film by supplying a first raw material that is a gas containing a chloride of a metal through a first coater; and prior to the forming of the transparent conductive film, forming on the undercoating film, at a film deposition rate slower than a film deposition rate for the transparent conductive film, a buffer layer that is a metal-containing thin film by a thermal decomposition method including supplying a second raw material containing a chloride of a metal through a second coater, wherein the transparent conductive film is formed directly on the buffer layer, the thickness of the buffer layer is 10 to 250 nm, the thickness of the transparent conductive film is 500 to 1000 nm, the film deposition rate for the buffer layer is 1250 to 2850 nm/min., the film deposition rate for the transparent conductive film is 6300 nm/min. or greater and, the haze ratio of the glass substrate having formed thereon the undercoating film, the buffer layer and the transparent conductive film is 29% or lower.
