  • Publication number: 20150060264
    Abstract: Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.

  • Patent number: 8518221
    Abstract: Certain example embodiments of this invention relate to techniques for making a coated article including a transparent conductive indium-tin-oxide (ITO) film supported by a heat treated glass substrate. A substantially sub-oxidized ITO or metallic indium-tin (InSn) film is sputter-deposited onto a glass substrate at room temperature. The glass substrate with the as-deposited film thereon is subjected to elevated temperatures. Thermal tempering or heat strengthening causes the as-deposited film to be transformed into a crystalline transparent conductive ITO film. Advantageously, this may reduce the cost of touch panel assemblies, e.g., because of the higher rates of the ITO deposition in the metallic mode. The cost of touch-panel assemblies may be further reduced through the use of float glass.
