Abstract

Transparent conductive coatings are polished using particle slurries in combination with mechanical shearing force, such as a polishing pad. Substrates having transparent conductive coatings that are too rough and/or have too much haze, such that the substrate would not produce a suitable optical device, are polished using methods described herein. The substrate may be tempered prior to, or after, polishing. The polished substrates have low haze and sufficient smoothness to make high-quality optical devices.
