Patent ID: 8163342

Claim:
A method of making a low-resistivity, doped zinc oxide coated glass article by chemical vapor deposition comprising: providing a hot glass substrate having a surface on which a coating is to be deposited, the surface being at a temperature of at least 400° C. and atmospheric pressure; controlling the premixing time of a zinc containing compound, water, and a dopant compound, wherein the dopant compound is an aluminum- or gallium-containing compound, and wherein the zinc containing compound and water are fed separately into a mixing chamber to form a gaseous precursor mixture; and directing the gaseous precursor mixture to the surface on which the coating is to be deposited as the substrate moves past the mixing chamber, wherein the gaseous precursor mixture is premixed in the mixing chamber for less than 1 second such that an aluminum- or gallium-doped zinc oxide coating is formed on the surface at a deposition rate of greater than 5 nm/second.
