Popis: Thin-film transistor liquid crystal display (TFT-LCD) panels of a high transmittance structure were fabricated by using a low-/spl kappa/ dielectric film as a passivation layer. The low-dielectric films were successfully deposited and patterned using a conventional plasma-enhanced chemical vapor deposition (PECVD) and plasma-assisted etching techniques. The interface between the a-Si channel and the overlaying passivation was modified by appropriate plasma treatment prior to the low-/spl kappa/ deposition. TFTs having the a-Si:C:O:H passivation showed a transfer characteristics similar to that of conventional TFTs. The high transmittance panel showed brightness approximately 30% higher than that of a standard panel without degrading other display characteristics, such as crosstalk.
