1. A process for depositing a transparent conductive oxide film on a substrate placed inside a chamber, said process comprising:

  • providing sources containing an oxygen-based liquid compound, a liquid compound of the metal intended to form the transparent conductive oxide film, and a dopant in gaseous or liquid form;

    establishing a temperature between 130 and 300°

    C. and a pressure between 0.01 and 2 mbar in said chamber; and

    thenbringing said sources into direct communication with said chamber, which has the effect of vaporizing said oxygen-based liquid compound, said liquid compound of the metal, and said dopant if the source of dopant is in liquid form at their surface, of drawing said vaporized compounds and said vaporized or gaseous form dopant up into the chamber without having to use a carrier gas, and of making said vaporized oxygen-based compound and said vaporized compound of the metal react therein with the dopant so that said oxide film is formed on the substrate.
