Abstract

A method of forming a textured layer of tin oxide on a vitreous substrate in which the thickness and degree of texture of the layer can be controlled independently of one another. The method comprises the steps of depositing a first film of tin oxide on the substrate by chemical vapor deposition from a first reactant mixture of tin chloride, water, and an alcohol and depositing a second film of tin oxide on the first tin oxide film by chemical vapor deposition from a second reactant mixture of tin chloride and water. Where the substrate is ordinary soda lime glass, it preferably is first coated with a film of silicon dioxide. The method permits deposition of substantially uniform layers of tin oxide in a continuous deposition process.
