There Is Sio2 Overlay Under Ito Coating,What Is That?

Si02 layer:
(1) The role of the SiO2 layer:
The main purpose is to prevent the metal ions in the soda-calcium substrate from diffusing into the ITO layer. It affects the conductivity of the ITO layer.

(2) Film thickness of SiO2 layer:
The standard film thickness is generally 250 ± 50 Å

(3) Other components in the SiO2 layer:
Usually, in order to improve the transmittance of ITO glass, a certain proportion of SiN4 is doped into SiO2.
