Method of making thermally tempered coated article with transparent conductive oxide (TCO) coating and product made using same
First Claim
1. A method of making a thermally tempered coated article including a transparent conductive film on a tempered glass substrate, the method comprising:
- providing a glass substrate;
sputter-depositing an amorphous film comprising Sn and Sb on the glass substrate;
thermally tempering the glass substrate with the amorphous film comprising Sn and Sb thereon; and
wherein heat used in said tempering causes the amorphous film to transform into a crystalline film, and wherein the crystalline film is transparent to visible light and electrically conductive.

Abstract
A method of making a coated article including a transparent conductive oxide (TCO) film supported by a tempered glass substrate is provided. Initially, an amorphous metal oxide film is sputter-deposited onto a non-tempered glass substrate, either directly or indirectly. The glass substrate with the amorphous film thereon is then thermally tempered using high temperatures. The thermal tempering causes the amorphous film to be transformed into a crystalline transparent conductive oxide (TCO) film. The heat used in the thermal tempering of the glass substrate causes the amorphous film to turn into a crystalline film, causes the visible transmission of the film to increase, and/or causes the film to become electrically conductive.
