ZnO (Zinc Oxide) coated glass substrates are used in various applications in the semiconductor and microelectronics industries. The ZnO coating on the glass substrate provides a wide band gap material that is highly transparent in the visible region and has good electrical conductivity. This makes it suitable for use in applications such as thin film transistors, touch panels, and displays. The ZnO coating can also provide a high surface area, which can enhance the performance of devices that rely on surface reactions. Additionally, ZnO coated glass substrates are relatively inexpensive, making them a cost-effective option for many applications.
