Abstract

The invention is a method of making a coated glass substrate having a low haze. A soda-lime glass substrate having at least one surface upon which a coating may be deposited is provided. The glass substrate is heated and maintained at a temperature sufficient to volatilize salts that may be formed during the depositing of a first coating on the glass substrate. A first gaseous precursor mixture including a halogen containing precursor, a metal precursor, an oxidizing agent, and an inert to carrier gas is directed toward and along the surface to be coated and reacting the mixture at or near the surface of the glass substrate to form a first coating containing a metal oxide coating. The glass substrate is cooled to a temperature to reduce crystalline growth in a second coating to be applied over the first coating. A second gaseous precursor mixture including a second metal precursor, an oxidizing agent, and an inert carrier gas is directed toward and along the coated surface of the glass substrate and reacting the mixture at or near the coated surface to form a metal containing coating. The glass substrate is cooled to an ambient temperature. The invention also includes a coated glass substrate produced in accordance with the aforementioned method.
