In this study, a low-k material, siloxane-based hydrogen silsesquioxane (HSQ) has been investigated for a passivation dielectric between the transistor and pixel levels in thin-film transistor (TFT) arrays. The characteristics of low-k dielectric film have been studied, especially under visible light illumination and electric operation. Compared with the conventional nitride film (k ∼ 7), the HSQ passivation layer (k ∼ 2.8) not only lowers the RC time delay in device, but also enhances the brightness of thin-film transistors liquid crystal displays (TFT-LCDs).
