Patent ID: 7608294

Claim:
A method of manufacturing a transparent substrate with a transparent conductive film, comprising a process of forming a transparent conductive film containing crystalline metal oxide as its main component on a transparent substrate by a pyrolytic oxidation method, in the method, a gaseous material containing a metal compound, an oxidizing material, and hydrogen chloride being supplied onto the transparent substrate, wherein the process comprises sequentially: a first step in which a mole ratio of the hydrogen chloride to the metal compound in the gaseous material is 0.5 to 5 and crystalline initial grains are formed on the transparent substrate; a second step in which the mole ratio is 2 to 10 and is higher than the mole ratio to be employed in the first step, and crystals of the metal oxide grow with the crystalline initial grains serving as starting points; and a third step in which the mole ratio is lower than 1.5 and the crystal growth is promoted.
