Abstract
A method for fabricating a passivation layer and a liquid crystal display. For the fabrication method, a substrate is provided. An oxide layer, a first silicon nitride layer, a spin-on-glass (SOG) layer, and a second silicon nitride layer are sequentially formed over the substrate. The liquid crystal display has a controller, a dielectric layer, a metal layer, an oxide layer, a first silicon nitride layer, a spin-on-glass layer, and a second silicon nitride layer. The dielectric layer is positioned over the controller. A metal layer is positioned over the dielectric layer. An oxide layer is formed over the metal layer. A first silicon nitride layer is formed over the oxide layer. A spin-on-glass (SOG) layer is formed over the first silicon nitride layer. A second silicon nitride layer is formed over the SOG layer.
